When you look at your surrounding environment, it might seem like you’re living on a flat plane. After all, this is why you can navigate a new city using a map: a flat piece of paper that represents all the places around you. This is likely why some people in the past believed the earth to be flat. But most people now know that is far from the truth.

You live on the surface of a giant sphere, like a beach ball the size of the Earth with a few bumps added. The surface of the sphere and the plane are two possible 2D spaces, meaning you can walk in two directions: north and south or east and west.

What other possible spaces might you be living on? That is, what other spaces around you are 2D? For example, the surface of a giant doughnut is another 2D space.

Through a field called geometric topology, mathematicians like me study all possible spaces in all dimensions. Whether trying to design secure sensor networks, mine data or use origami to deploy satellites, the underlying language and ideas are likely to be that of topology.

The Shape of the Universe

When you look around the universe you live in, it looks like a 3D space, just like the surface of the Earth looks like a 2D space. However, just like the Earth, if you were to look at the universe as a whole, it could be a more complicated space, like a giant 3D version of the 2D beach ball surface or something even more exotic than that.

While you don’t need topology to determine that you are living on something like a giant beach ball, knowing all the possible 2D spaces can be useful. Over a century ago, mathematicians figured out all the possible 2D spaces and many of their properties.

In the past several decades, mathematicians have learned a lot about all of the possible 3D spaces. While we do not have a complete understanding like we do for 2D spaces, we do know a lot. With this knowledge, physicists and astronomers can try to determine what 3D space people actually live in.

While the answer is not completely known, there are many intriguing and surprising possibilities. The options become even more complicated if you consider time as a dimension.

To see how this might work, note that to describe the location of something in space – say a comet – you need four numbers: three to describe its position and one to describe the time it is in that position. These four numbers are what make up a 4D space.

Now, you can consider what 4D spaces are possible and in which of those spaces do you live.

Topology in Higher Dimensions

At this point, it may seem like there is no reason to consider spaces that have dimensions larger than four, since that is the highest imaginable dimension that might describe our universe. But a branch of physics called string theory suggests that the universe has many more dimensions than four.

There are also practical applications of thinking about higher dimensional spaces, such as robot motion planning. Suppose you are trying to understand the motion of three robots moving around a factory floor in a warehouse. You can put a grid on the floor and describe the position of each robot by their x and y coordinates on the grid. Since each of the three robots requires two coordinates, you will need six numbers to describe all of the possible positions of the robots. You can interpret the possible positions of the robots as a 6D space.

As the number of robots increases, the dimension of the space increases. Factoring in other useful information, such as the locations of obstacles, makes the space even more complicated. In order to study this problem, you need to study high-dimensional spaces.

There are countless other scientific problems where high-dimensional spaces appear, from modeling the motion of planets and spacecraft to trying to understand the “shape” of large datasets.

Tied Up In Knots

Another type of problem topologists study is how one space can sit inside another.

For example, if you hold a knotted loop of string, then we have a 1D space (the loop of string) inside a 3D space (your room). Such loops are called mathematical knots.

The study of knots first grew out of physics but has become a central area of topology. They are essential to how scientists understand 3D and 4D spaces and have a delightful and subtle structure that researchers are still trying to understand.

In addition, knots have many applications, ranging from string theory in physics to DNA recombination in biology to chirality in chemistry.

What Shape Do You Live On?

Geometric topology is a beautiful and complex subject, and there are still countless exciting questions to answer about spaces.

For example, the smooth 4D Poincaré conjecture asks what the “simplest” closed 4D space is, and the slice-ribbon conjecture aims to understand how knots in 3D spaces relate to surfaces in 4D spaces.

Topology is currently useful in science and engineering. Unraveling more mysteries of spaces in all dimensions will be invaluable to understanding the world in which we live and solving real-world problems.

To help find answers, researchers at the Institute for Neuroscience, Neurotechnology, and Society (INNS) are using math, data, and AI to unlock the secrets of thought. Together they are helping turn the brain’s raw electrical “noise” into real insights about how people think, move, and perceive the world.

Fair warning: Prepare your neurons for the complexity of this brain research ahead.

Building AI Like a Brain

What if artificial neurons in AI programs were arranged as they are in the brain?

AI programs would then help us understand why the brain is organized the way it is. This neuro-AI synthesis would also work faster, use less energy, and be easier to interpret. Creating such systems is the goal of Apurva Ratan Murty, an assistant professor of Psychology who is creating topographic AI models like the one above of three domains — vision, audition, and language inspired by the brain. In the near future, he predicts doctors might be able to use these patterns to predict the effects of brain lesions and other disorders. “We’re not there yet,” he says. “But our work brings us significantly closer to that future than ever before.”

Computing Thought and Movement

How cats walk keeps Chethan Pandarinath on his toes. This biomedical engineer uses sensors to analyze how two sets of feline leg muscles — flexors and extensors — are controlled by the spinal cord. Understanding how that happens could help patients partially paralyzed from spinal cord injuries, strokes, or progressive neuro-degenerative diseases get back on their feet again. “My lab is using AI tools that allow us to turn complex spinal cord activity data into something we can interpret. It tells us there’s a simple underlying structure behind the complex activity patterns,” says the associate professor.

Revealing the Brain’s Spike Patterns

“The brain is like a symphony conductor,” says Simon Sponberg. “Individual instruments have some independent control, but most of the music comes from the brain’s precise coordination of notes among the different players in the body.” This physics professor studies the fantastically fast-beating wings of the hummingbird-sized hawk moth (Manduca sexta). Its agile flight movement comes as a result of spikes in electrical activity in 10 muscles. Sponberg found something that surprised him — the brain focuses less on creating the number of spikes than in orchestrating their precise patterns over time. To Sponberg, every millisecond matters. “We are just beginning to understand how the nervous system first acquires precisely timed spiking patterns during development,” he says.

Predicting Decisions Through Statistics

Put a mouse in a maze with food far away, and it will learn to find it. But life for mice — and people — isn’t so simple. Sometimes they want to explore, only want water, or just want to go home. What’s more, animals make decisions based on their history, not just on how they feel at the moment. To dig deeper into the decision-making process, Anqi Wu, an assistant professor in the School of Computational Science and Engineering, is giving mice more options. By using a new computational framework called SWIRL (Switching Inverse Reinforcement Learning), her findings have outperformed models that fail to take historical behavior into account. “We’re seeking to understand not only animal behavior but also human behavior to gain insight into the human decision-making process over a long period of time,” she says.

Modeling the Mind’s Wiring With Math

Connectivity shapes cognition in the cerebral cortex, a layered structure in the brain. The visual cortex, in particular, processes visual data from the retina relayed through the Lateral Geniculate Nucleus (LGN) in the thalamus, and directs it to the correct cognitive domain in the brain. How it does this is the mystery that computational neuroscientist Hannah Choi wants to solve. “The big question I’m interested in is how network connectivity patterns in the architecture of the LGN are related to computations,” says this assistant math professor. To find answers, she shows mice repeated image patterns such as flower-cat-dog-house and then disrupts the pattern. The goal? To grasp how the thalamus’s nonlinear dynamical system works. If scientists and doctors better understand how brain regions are wired together, such knowledge could lead to better disease treatment.

This story was originally published through the Georgia Tech Alumni Magazine. Read the original publication here.

Caleb Adams, a business administration major, and Marielle Frooman, a biochemistry major, have charted their own distinct paths, yet both equally embody the academic excellence, leadership, and impact at the heart of the Love Family Foundation Award.

The winners are selected by the academic associate deans in coordination with the Office of Undergraduate Education and Student Success, and each recipient will receive a $6,000 monetary award.

“The selection committee felt that both finalists exemplified the spirit and intent of this award,” said Steven Girardot, vice provost for Undergraduate Education and Student Success. “From a pool of six outstanding finalists, it was clear that these two students stood apart. Rather than forcing a distinction between equally exceptional individuals whose achievements span very different disciplines, the committee chose to recognize both. Caleb and Marielle represent an exceptional level of achievement, curiosity, and commitment to impact that defines the very best of Georgia Tech undergraduates.”

Building a Business Career

Finance captured Caleb Adams’ attention early, sparked in part by conversations with his father — a Georgia Tech mechanical engineering alumnus — and solidified when Adams bought his first stock at 13. Captivated by the way investing touches everything and everyone in the economy, Adams set his sights on an education in Georgia Tech’s Scheller College of Business.

A Stamps President’s Scholar, Adams embraced the scholarship’s emphasis on academic excellence, leadership, and service. His academic path was shaped as much by the classroom as by the opportunities he pursued beyond it.

Adams has immersed himself in campus life, seeking experiences that have allowed him to explore finance in academic and extracurricular settings while consistently finding opportunities to give back to his peers. One of the most influential was his role on the Georgia Tech Student Foundation Investments Committee, where he served as technology sector head and managed a $300,000 portfolio. Working with actual money and real stakes, he sharpened his financial modeling and presentation skills while directing funding back to student organizations across campus.

As a Scheller Business Ambassador, Adams welcomed prospective students and families and had the space to share student perspectives with college leadership. That commitment to helping others navigate business and finance also showed up in his participation in the Scheller Mentor Program, hosting personal finance education workshops, and working as a teaching assistant for an accounting course he took as a first-year student. In earlier semesters, Adams explored finance and strategy through the Venture Capital Club, Undergraduate Consulting Club, and Emerging Leaders Advisory Board.

His journey was intentional from the start, and faculty who have worked with him recognize him for his accomplishments and everything it took to get there.

“Even as a first-year student, Caleb wasn’t just chasing the next opportunity,” noted Craig Womack, associate dean for undergraduate programs at Scheller. “He was thoughtful about how each experience connected to the kind of person and leader he wanted to become.”

Womack was instrumental in Adams’ decision to attend Georgia Tech, providing guidance before Adams began as a first-year and helping connect him with professors and organizations that would influence his academic and professional journeys.

Adams’ intentionality extended beyond the classroom, and when finance wasn’t capturing his attention, travel offered another way for him to feed his curiosity of how the world works. In 2025, Adams helped organize the Academic Search for Knowledge trip to Japan for fellow Stamps President’s Scholars, which helped his goal of visiting every continent and further broadened his global perspective.

The focus and discipline characterizing Adams’ academic journey has also guided him through a demanding slate of internships, including roles at Capital One, Airbnb, AeroVect, and ultimately Morgan Stanley, where he earned a full-time offer and will begin his career as an investment banking analyst in New York City after graduation. Working for Morgan Stanley had been his goal long before his first day of college.

“It’s definitely an intense job,” he acknowledged, “but it’s incredibly interesting, high-value work. The exposure you get, the training you get, the skills and networks — they’re unbeatable and unmatched.”

As he prepares to graduate and step into the fast pace of Wall Street, Adams sees the award less as a finish line and more of a reminder of where he started and the community that shaped him along the way.

“More than anything, it’s solidified how connected I feel to Tech,” he said. “I want to stay involved and give back so future students have the same kind of support and opportunity I did.”

Finding Joy — and Purpose — in the Lab

Where Adams found his footing in finance, Marielle Frooman discovered hers in the lab, driven by an insatiable curiosity and infectious enthusiasm for chemistry.

Frooman was drawn to Georgia Tech by its research culture and the energy of its student community. She joined her first lab early in her undergraduate career, unsure of exactly where that path would lead, but eager to get hands-on experience as soon as possible.

For two years, Frooman conducted biochemistry and structural biology research in the McShan Lab, working under Andrew McShan, assistant professor in the School of Chemistry and Biochemistry. Frooman’s time in the McShan Lab was foundational in shaping her technical abilities and preparing her for a research-intensive career.

“I had never done research before, and I wasn’t equipped to handle the amount of failure that comes with it,” Frooman said, reflecting on the formative experience. “Professor McShan really helped me change my outlook, to see failure as a learning experience and to use it to push a project forward.”

McShan described Frooman as an exceptional undergraduate researcher and peer leader.

“Marielle is not only an extremely talented researcher, but also a caring mentor and motivated future leader who wants to change the world,” they said. “She is the best undergraduate researcher I have ever worked with, and I guarantee she will make a big impact in whatever field she chooses to pursue.”

That strong biochemistry foundation gave Frooman the confidence to follow where her curiosity led next. After falling in love with organic chemistry through coursework and serving as a synthesis lab Teaching Assistant and organic chemistry peer tutor, she transitioned into researching with Will Gutekunst, associate professor in the School of Chemistry and Biochemistry. The shift built directly on the skills she developed in the McShan Lab while clarifying her long-term goals of pursuing graduate study and eventually contributing to the synthetic field as an academic researcher.

That trajectory has already earned her national recognition. Frooman is a 2026 recipient of the National Science Foundation Graduate Research Fellowship Program for chemical synthesis and was also named one of the year’s Outstanding Undergraduate Biochemistry or Chemical Biology Students by the American Chemical Society’s (ACS) Division of Biochemistry and Chemical Biology.

Outside of research, Frooman’s energy spills into nearly every corner of campus life. She has served as president of the Student Affiliates of the ACS, president of Cleanup Crew, president of public relations for the GT tour guides, and an active member of Greek life — all while pursuing research and mentoring fellow students.

“Everything I do, I do because I love it,” she said. “If I wasn’t this busy, I’d feel like I was missing out on something that really matters to me.”

As Frooman heads toward graduation and prepares to pursue a Ph.D. in Chemistry at the University of Michigan, receiving the Love Award feels deeply validating, both personally and for those who helped get her here.

“It’s invigorating,” Frooman said, reflecting on the honor. “It’s a culmination of my undergraduate work, but even more, it’s a testament to how supportive this community has been over my four years here. I would not be receiving this award without everyone who was right next to me along the way.”

A Shared Recognition

Adams and Frooman took different routes at Georgia Tech, but each approached their time here with intention. While one followed markets and global finance and the other immersed herself in scientific discovery, their stories converge in the values the Love Family Foundation Award was created to recognize: academic excellence and a commitment to making a difference.

The Truman Scholarship is awarded annually to a select group of students nationwide who demonstrate outstanding leadership potential, academic excellence, and an enduring commitment to making a difference. Named after President Harry S. Truman, the scholarship supports students in their graduate education and careers addressing society’s most pressing challenges.

“Taylor exemplifies the kind of leader we strive to develop,” said Georgia Tech President Ángel Cabrera. “Her commitment to strengthening public institutions reflects our motto of Progress and Service. Her selection as a Truman Scholar, one of the nation’s most prestigious fellowships for public service, is an exceptional achievement, and we are incredibly proud of her.”

A Commitment to Rebuilding Trust in Public Institutions

Witte, who hails from Highlands Ranch, Colorado, is pursuing dual bachelor’s degrees while maintaining a 4.0 GPA. She balances an ambitious academic load with dedicated involvement in campus leadership, undergraduate research, and national public service experiences.

Motivated by the erosion of trust in American public institutions, Witte aims to strengthen government decision-making through rigorous economic analysis, transparent data practices, and effective regulation. Instead of viewing public trust as just another policy area, Witte sees it as the very foundation upon which all governance rests.

“While several social issues, from the climate crisis to criminal justice, demand our attention,” she explains, “our ability to tackle these challenges is only as strong as our collective faith in the institutions meant to do so. Responsible data stewardship is the first step to ensuring that communities see themselves represented in the policies that shape their lives.”

That philosophy was shaped in part by her work at the Federal Reserve Board of Governors, where she served as a statistics and data management intern in 2025. The experience reinforced her belief that sound regulation, grounded in high-quality evidence and community realities, is essential to restoring confidence in government.

It’s a perspective that also guides her long-term goals. As a Truman Scholar, Witte plans to pursue a joint J.D. and Ph.D. in economics. She hopes to work in the U.S. Office of Management and Budget, specifically the Office of Information and Regulatory Affairs, where economic analysis and regulatory oversight intersect.

Leadership at Georgia Tech and Beyond

Witte’s leadership record at Georgia Tech is extensive. She has served as an advisor for the Seek Discomfort First-Year Leadership Organization and is currently a justice on the Undergraduate Judiciary Committee within Georgia Tech’s Student Government Association.

She has also played a key role in institutional service and advocacy. As an ambassador for the Ivan Allen College of Liberal Arts, Witte helps lead Shadow Day, the College’s largest outreach event for prospective students. Previously, she sat on the Ivan Allen College Advisory Board and is now the sole undergraduate member of the School of Economics Chair Search Committee.

In addition, Witte has helped oversee the Georgia Tech Stamps Summit as conference chair, building intellectual community among fellow scholars committed to leadership and service.

Chaffee Viets, executive director of the Office of Scholar Programs, notes that Witte’s leadership is defined as much by reflection as ambition.

“Taylor is a thinker,” Viets said. "Someone who asks the same questions of herself that she might ask of society: How is this path I am on going to lead to real impact? In her answers, I see deliberative leadership and extraordinary potential.”

Bridging Liberal Arts and Technical Education

As a liberal arts student at a leading technical institute, Witte has made it a personal mission to demonstrate the essential role of economics, public policy, and the humanities in shaping technological innovation and governance. She currently serves as a teaching assistant in the School of Mathematics, one of only a handful of liberal arts majors among a large cohort, where she works to make complex mathematical concepts accessible and applicable for all her students.

“In everything I do on campus, I want to show that liberal arts majors can learn alongside STEM-focused students, and also lead among them and contribute meaningfully to the Institute’s mission of advancing technology and improving the human condition,” she said. “My experiences at Tech have left me better prepared to navigate a public-sector career in an increasingly technical world.”

Looking ahead, Witte remains focused on the long-term work of strengthening democratic institutions.

“To say we are navigating difficult and uncertain times would be an understatement,” she says. “But the most powerful force in this moment is one within our control: our collective decision to believe in the institutions we build, and to demand that they rise to meet us. It’s our choice to make.”

GT² is a newly established research initiative at Georgia Tech that focuses on discovery science, engineering innovation, and AI-enabled decision tools to address urgent challenges at the intersection of environmental and community resilience in the Southeast. The initiative fosters research in direct service to regional communities through public-private partnerships, and it provides opportunities for graduate student engagement.

The BHIC-GT² research fund and partnership will pursue shared initiatives in the fields of coastal sustainability, ecosystem health, and environmental resilience. By combining BHIC’s applied, field-based conservation work with Georgia Tech’s expertise in technological innovation and data analysis, new opportunities for impactful research will be created through graduate student projects and community engagement.

About the Partnership
Like the GT² initiative, BHIC’s Johnston Center for Coastal Sustainability was created to translate research into real-world impact. BHIC established the Johnston Center as a research partnership and education hub for sustainability initiatives on Bald Head Island, with the broader goal of advancing coastal sustainability across the Southeast. Seed funding for the Center was provided in 2021 by Dick and Pat Johnston, longtime supporters of BHIC. 

Dick, a Georgia Tech IM 1962 alumnus, and Pat Johnston shared their enthusiasm for the BHIC and Georgia Tech collaboration, noting: 

“We are delighted to see our two favorite institutions come together through this partnership. It brings additional resources, expertise, and leadership to our shared focus on keeping the historic tagline ‘Living in Harmony with Nature’ in the hearts of future generations.”

Joel Kostka, Faculty Director of GT² who also serves as Tom and Marie Patton Distinguished Professor and associate chair for Research in the School of Biological Sciences with a joint appointment in the School of Earth and Atmospheric Sciences at Georgia Tech added:

“The Bald Head Island Conservancy and its Johnston Center for Coastal Sustainability exemplify how place‑based conservation and rigorous science can work together to create real impact. The Bald Head Island Conservancy’s long‑term stewardship, research infrastructure, and commitment to translating science into action make it an ideal partner for Georgia Tech for Georgia’s Tomorrow as we advance collaborative research that strengthens coastal resilience across the Southeast.”

This partnership will focus on Georgia Tech graduate student research projects that use innovative technology and data analyses to directly support the conservation work of BHIC.

Graduate student research already plays an important role in BHIC’s conservation efforts. Gabie Krueger, a Georgia Tech Ph.D. student in Ocean Sciences and Engineering and BHIC’s 2025-26 Johnston Graduate Fellow in Coastal Sustainability, has been working with BHIC scientists on a salt marsh ecology project that examined how ribbed mussels and fiddler crabs influence the health of Bald Head Island’s dominant salt marsh grass Spartina alterniflora. These flora-fauna interactions serve as primary indicators of marsh health, so her research is important for understanding the resilience of Bald Head Island’s salt marsh to environmental concerns such as sea-level rise and development.

Through the BHIC-GT² partnership, Georgia Tech student researchers who work with the Conservancy will also gain invaluable experience with local conservation efforts and community engagement.

G. Christopher Shank, Ph.D., Executive Director of BHIC, commented:

“The Bald Head Island Conservancy is thrilled about this opportunity to create a formal research partnership with Georgia Tech, one of the nation’s most esteemed research universities. It is recognition of the quality of conservation studies we are currently pursuing at the Conservancy and it also augments the impact of our work for BHI and beyond because of the technological and data analysis talent that Georgia Tech for Georgia’s Tomorrow will bring to this partnership.”

Why This Matters
This research fund and partnership represents an important step forward in strengthening connections between academic research and applied conservation institutions. Together, BHIC and GT² aim to inform coastal management decisions, support resilience planning, engage students, and advance research that benefits coastal ecosystems and communities across the southeastern U.S.

Looking Ahead
Additional details about joint initiatives, research priorities, and collaborative opportunities will be shared in the coming months.

The paper, The Borderlands of Foldability: Lessons from Simplified Proteins, is a meta-analysis of six decades of protein research and reveals that ancient proteins may have been far more complicated and dynamic than previously thought. 

Recently published in the journal Trends in Chemistry, the study includes Georgia Tech researchers Lynn Kamerlin, professor in the School of Chemistry and Biochemistry and Georgia Research Alliance Vasser-Woolley Chair in Molecular Design, and Quantitative Biosciences Ph.D. candidate Alfie-Louise Brownless.

Co-authors also include Institute of Science Tokyo graduate student Koh Seya and Liam M. Longo, who serves as a specially appointed associate professor at Science Tokyo and as an affiliate research scientist at the Blue Marble Space Institute of Science.

The research has implications ranging from the origins of life and the search for life in the universe to cutting-edge medical innovation. “One of the biggest unanswered questions in science is how life first began,” says Kamerlin, who is a corresponding author of the study. “Understanding how the first protein-like molecules formed and what the earliest proteins may have been like is a key part of that puzzle.”

“Proteins power our bodies — and all life on Earth,” she adds. “Simply put, the evolution of proteins is the reason that we’re able to have this conversation at all.”

A Protein Folding Paradox

If proteins are the scaffolding of life, amino acids are the components that make up that scaffolding. “Today, an average protein is constructed from a chain of about 300 amino acids, involving 20 different types of amino acids,” Kamerlin shares. Proteins fold when these chains twist into a specific 3-dimensional shape, creating structures critical for biology.

However, while these folds are essential, exactly how a protein knows which way to fold remains a mystery. “We know that proteins didn’t just fold randomly,” Kamerlin shares, “because randomly trying all possible configurations would take a protein longer than the age of the universe.”

It’s a cornerstone problem in biological science called “Levinthal’s Paradox,” and highlights a fundamental mystery: Proteins fold incredibly quickly into very specific combinations — but like a sheet of paper spontaneously folding into an origami swan, researchers don’t know how proteins “choose” the folds they make.

“We can predict what a protein will look like, but can’t tell you how it got there,” Kamerlin adds. “That’s what we’re interested in exploring: how small early proteins developed into the complex proteins that support every living thing on today’s Earth.”

Simple Letters, Sophisticated Structures

Early proteins likely had access to just half of today’s amino acids. “About 10-12 amino acids were likely available on early Earth,” Kamerlin says. Like writing a story with just the letters “A” through “L,” researchers assumed that the ‘vocabulary’ proteins could build from such a limited amino acid alphabet would also be constrained.

“There is a language to protein folding,” Kamerlin explains. “That language is hidden in their structures. Our research is in trying to understand the rules — the grammar and vocabulary that dictate a protein fold.” 

The grammar they discovered was surprising: with a combination of creative techniques and environmental support, complex structures can arise from limited amino acid alphabets. 

“We found that it is possible to develop complex folds with very simple tools — and certain environments, like salty ones, can help support that,” Kamerlin shares. “Early proteins could also cross-link and associate, interacting like LEGO blocks to create more complex structures.”

Pioneering Proteins

Now, the team is conducting research in environments that could mimic conditions on early Earth — aiming to discover more about how these regions could have given rise to today’s complex proteins. “This aspect of our research also ties into the amazing space research happening at Georgia Tech,” Kamerlin says. “While we’re interested in understanding early life on Earth, our work could help inform where best to look for evidence of life beyond our planet.”

Kamerlin specializes in creating computer models that simulate possible scenarios – creating an opportunity to quickly and efficiently test many theories. The most compelling of these can then be tested by her collaborator and co-author at Science Tokyo, Liam Longo, in lab experiments. 

Protein folding is also at the forefront of medical innovation, ranging from diagnostic tools to cancer treatments and neurodegenerative diseases. “In the broader scope, we’re interested in discovering what we can design, what we can stress test, and what we can reconstruct with AI and other computational tools,” Kamerlin says. “Because if you can understand how proteins fold, you gain the ability to design them.”

Georgia Tech's 11th annual Three Minute Thesis (3MT) competition took place on Tuesday, April 7th, where 12 scholars presented their innovative research in just three minutes to a non-specialist audience. After five preliminary rounds and Tuesday’s climactic competition, five graduate students were named winners and awarded research travel grants. 

This year’s selection committee chose projects focused on artificial intelligence, therapeutic drug development, data privacy, energy efficiency, and cancer treatment.

Working with collaborators at University College London (UCL), Georgia Tech researchers used computer models to reveal how, during early development, forces generated by cells physically pull the neural tube closed — like a drawstring. This discovery offers new insight into a critical process that, when disrupted, can result in severe birth defects such as spina bifida.

“Understanding a complex developmental process like neural tube closure requires a highly interdisciplinary approach,” said Shiladitya Banerjee, an associate professor in the School of Physics. “By combining advanced biological imaging with theoretical physics, we were able to uncover the mechanical rules that drive cells to close the tube. My lab builds computational models to uncover the physical rules of living systems. The neural tube is an ideal focus because its formation requires incredible mechanical coordination.”

The researchers presented their findings in Current Biology. 

Closing the Gap

The UCL team studied mouse embryos, which develop similarly to humans, and Georgia Tech researchers used that data to construct their models. From the data, they identified the fundamental physics mechanism that enables neural tube closure in part of the brain. This mechanism, called a “purse string,” is made of actin, a pivotal protein that forms a cell’s skeletal structure. As the purse strings tighten, the tube closes.

“These actin molecules are very important because they give rigidity and shape to cells,” Banerjee said.

“During neural tube closure, actin filaments form a ring around the opening and engage molecular motors — proteins that generate forces inside cells,” he said. “As these motors pull on the actin, they generate tension that tightens the ring and draws the tube closed.”

Stretching to Fit

As the actin ring tightens, cells stretch and elongate, causing them to align and move together in a synchronized pattern, like a school of fish. This coordination allows the cells to move faster and more efficiently, increasing tension and driving a feedback loop that helps seal the neural tube.

The team built a computer model to show how this feedback loop leads to successful neural tube formation. Further research using the model could help explain why the neural tube fails to close.

“Physics-based modeling of cell and tissue mechanics allows us to connect the dots between developmental stages in a way that is both robust and quantitative, simulating experiments that are impossible in biological tissues,” said Gabriel Galea, the study co-author and UCL group leader. “In this case, it allowed us to explain how a cell’s mechanical experience impacts its current and future shapes during a critical step of brain development.”

Beyond neural tube development, the findings highlight the power of physics-based modeling to explain complex biological processes that can’t be observed directly. The researchers say this approach could be applied to other stages of human development where forces, motion, and timing are just as critical.

The computational research at Banerjee Lab is funded by the National Institute of General Medical Sciences

Lloyd George was back in the gym just two weeks after completing 2,002 muscle-ups in 24 hours in July of 2025, which broke the world record. He immediately started training for an even more challenging feat—the world record for the most muscle-ups done on a gymnastic ring in 8, 12, and 24 hours.

On Sunday, April 12, 2026, he surpassed all three, completing 900 ring muscle-ups in 8 hours, 1,100 in 12 hours, and 1,320 in 24 hours. (The records are unofficial until they can be reviewed by Guinness World Records.)

“I’ve sort of got a recipe for these world records now,” says Lloyd George, who used the challenge to raise money for the Wounded Veterans Relief Fund, a charity that helps veterans receive dental care. 

Since the summer of 2025, he steadily increased his training volume, pushing past 17,000 total ring muscle-ups, and completing longer sessions, including a six-hour effort of 722 ring muscle-ups.

A Harder Variant of A Muscle-Up

Ring muscle-ups are a more demanding variant of the standard bar muscle-up. The sway of the rings introduces instability and makes muscles work harder when the ropes move. The grip is also different. 

“You wrap your wrists around the rings almost like you’re trying to arm wrestle them,” Lloyd George says. Put in physics terms—a field he knows well as a doctoral student at Duke University researching trapped ions for quantum computing—the rings introduce four more degrees of freedom. 

The Math Behind His Three Attempts

His decision to attempt three world records came down to simple math. The current 8-hour record is 843, while the 24-hour record is 1,308. No formal record exists for the 12-hour category. 

“I realized that if I do two ring muscle-ups every minute, at that pace I’d get to 960 in 8 hours. There isn’t a 12-hour record, and there are for other calisthenic records, so I thought I could set that one, too,” he says. 

When he broke the bar muscle-up record in 2025, he didn’t know how challenging the final hours would be. The last 50 reps were grueling, and with the support of his friends and family who cheered him on, he pushed past his limits. Knowing what the challenge will feel like changes his mental preparation this time around.

“I think you have to play with the mental game and really ask yourself, ‘Why am I doing this?’ especially on those difficult training days. For those, I think about the charity I’m trying to raise money for that I believe in, and that this is one more opportunity to challenge myself.” 

“There is incredible power in alumni stories,” says Susan Lozier, dean of the College of Sciences and Betsy Middleton and John Clark Sutherland Chair. “It’s inspiring for students to speak with alumni in the workforce, hear how they landed their first jobs, and learn from their successes — and their setbacks.”

Claire Haskell (Mathematics 2025) recently obtained her first job with Deloitte and attended the dinner to offer perspective to current students.

“I want to reassure students still in school that, even in today’s uncertain times, getting a job is still really doable and not as out of reach as it seems. Meeting Tech alumni is a great first step.”

A Night of Networking

College of Sciences Career Educator Program Manager James Stringfellow and Director of Alumni Relations Leslie Roberts organized the annual signature career event.

“We put on events like this because we want all of our students ready for their next opportunity,” says Stringfellow.

Second-year psychology major Aleena Sange attended the event for the first time, and says she will be back next year. “The alumni were really helpful and reassuring,” says Sange. “I learned what employers look for in a resume and even received advice about contract negotiations and retirement.”

First-year astrophysics student Shannon Callahan agrees. “What struck me the most was hearing how well Georgia Tech prepares you for the workforce. It gave me a lot of confidence to hear that Tech alumni hit the ground running because they’re used to learning quickly.”

The evening included casual and more structured networking, with students rotating between tables on topics such as “Using AI in the Workplace,” “Handling Conflict,” and “How to Get Hired in the Real World.”

Janessa Rowland (Earth and Atmospheric Sciences 2014) works as an operations program manager for the Georgia Department of Natural Resources. She encouraged students to think beyond their major

“Sometimes an internship or class outside your major can open up the door for what you can do after Georgia Tech.”

Morgan Foreman (Psychology 2017), a technical product manager at IBM, offered encouraging insight: “People often tell you college is the best years of your life. Georgia Tech also sets you up for your dream life after college.”

2026 Internship Employer of the Year

During the festivities, Stringfellow announced Boehringer Ingelheim as the Internship Employer of the Year. The award honors a company that provides a high-quality learning environment for student interns. 

Arya Akbarshahi, a biochemistry major who spent a semester doing a co-op job at the company, presented the award, thanking the biopharmaceutical company active in both human and animal health for the learning experience provided.

“Co-oping at Boehringer Ingelheim was one of the most formative experiences in my training. From day one, I was trusted as a scientist, which allowed me to formulate hypotheses and execute experiments with direct implications for drug development strategy and decisions,”  says Akbarshahi. 

After presenting the award to Boehringer Ingelheim Senior Scientist Marc Sprouse, Akbarshahi also presented a surprise mentorship award to Sprouse.

“Marc was an exceptional mentor,” says Akbarshahi. “He challenged me to think critically about the biology, not just the assay, and consistently created space for me to take ownership and operate at a higher level.”

Sprouse accepted both awards and spoke of the benefits of working while still in school: “Getting real-world work experience while in school sets students up for success. I encourage all College of Science students to check out our website and apply for future co-ops and internships."

This is the third time the class has been offered, but the first to include an extended community-based learning experience. 

“The students were able to see firsthand how concepts discussed in the classroom translated into real infrastructure decisions shaping vulnerable coastal communities,” says Robel, an associate professor in the School of Earth and Atmospheric Sciences.

In previous years, the course relied on guest speakers, often remote, to provide real-world insights. Robel and Macedo, an associate professor in the School of Civil and Environmental Engineering, advocated for this year’s field trip to give students direct exposure to how the concepts taught in class are used in coastal communities.  

“Places like Savannah, Tybee Island, and Charleston aren’t planning for a distant future; they’re making real infrastructure decisions right now,” explains Robel.

Coastal case studies

On Tybee Island, city leaders and U.S. Army Corps of Engineers staff discussed with students how to balance tourism, environmental protection, and shoreline preservation. Site visits highlighted tide gates and living shorelines as flood mitigation strategies. 

Then, in Savannah, students met with city staff to explore challenges facing historic, low-lying cities and visited the Pin Point Heritage Museum where Gullah-Geechee community leaders spoke about the cultural, environmental, and equity dimensions of flood planning. 

The trip concluded in Charleston with discussions led by the city’s chief resilience officer and tours of the Low Battery Seawall and a neighborhood pump station, illustrating how flood infrastructure can serve both functional and public-facing roles. Students also visited JMT, the engineering firm behind several of the projects studied, where engineers discussed design trade-offs and career paths in coastal and municipal infrastructure.

Regional risks, real responses

“The regional context is especially important because Georgia Tech graduates are heavily concentrated in the Southeast, and many go on to careers designing, managing, or approving infrastructure projects in coastal communities,” says Robel. “With a more concentrated vulnerability to sea-level rise in the Southeast than any other part of the United States, the most potential flooding is likely to occur here in the Atlantic Southeast and Gulf Coast.”

He adds that “if we’re educating the scientists, engineers, and decision-makers who will be working in these communities, they must understand the practicalities of flood resilience and how to make informed decisions based on the best current science.”

Although the idea for the field experience had been years in the making, it became feasible only recently with support from an internal grant on sustainability education and community-based learning administered by the Center for Sustainable Communities Research and Education. Robel also emphasized the importance of long-standing relationships with coastal communities and governments in making the trip a success.

“We reached a point where we had both the resources and the relationships to make the experience meaningful,” he shares.

Career context

The students met professionals from a wide range of career paths, including federal and local government agencies, private engineering firms, and municipal stormwater departments. 

“A major goal of the trip was giving students the chance to see what career paths in coastal resilience really look like,” says Robel. “Those conversations helped students understand not just the technical work, but also the financing, politics, and community concerns that shape infrastructure decisions — parts of the job that are harder to capture in the classroom.”

Students enjoyed the opportunity to get real-world context:

“This trip made me reconsider my post-graduation plans. I used to think the geology industry was just oil and gas, but this trip showed me different ways I can apply my skills to help the environment as well as local communities in their efforts to adapt to sea-level rise concerns,” says Mandala Pham, a Ph.D. student studying geophysics.

“The most valuable part of the experience was observing sea-level rise mitigation infrastructure in-person, and the trip was a great experience overall to make new friends and gain valuable experiences,” adds Alexander Brison, a fourth-year environmental engineering major.

By grounding classroom concepts in real places and real decisions, the Spring Break field experience reinforced the course’s goal: preparing students to engage thoughtfully with the challenges coastal communities are already facing.

The two‑day event took place Feb. 4 – 5, coinciding with the Critical Minerals Ministerial hosted by U.S. Secretary of State Marco Rubio in Washington, D.C., on Feb. 4, which brought together more than 50 nations to strengthen and diversify global critical mineral supply chains. During this ministerial, U.K. Minister Seema Malhotra and U.S. Under Secretary of State Jacob Helberg signed a Critical Minerals Memorandum of Understanding, strengthening bilateral cooperation between the United States and the United Kingdom on critical mineral supply chains. 

These broad efforts are supported by White House Executive Order 14363, which defines the Genesis Mission and aims to accelerate scientific discovery through AI. The order identifies critical minerals supply chain resilience as a national security imperative.

In Atlanta, these themes were brought to life in real time. The GEMs-4 workshop brought together researchers, policymakers, national labs, industry leaders, and workforce organizations from both the U.S. and the U.K. to address shared challenges in technology translation, permitting, investment, and talent development. 

The state of Georgia’s integrated ecosystem, linking research universities, legacy industries, technical colleges, national labs, and public‑private partnerships, served as a case study. Presenters highlighted how existing industrial assets in the Southeast are being incorporated into emerging clean energy and critical minerals supply chains, offering a model for other regions seeking to build capabilities around extraction, processing, and manufacturing.

A U.K. member of Parliament representing Cornwall, where the U.K. has lithium reserves and deep critical mineral expertise, joined the convening, as well as representatives from the U.K. Critical Mineral Association, Camborne School of Mines, and the University of Kent. Together, they explored opportunities and challenges, from a fundamental science to a commercialization perspective grounded in real-world experience. 

The alignment between the ministerial in Washington and the expertise present in Atlanta demonstrated the value of state-level engagement and how national agreements translate into practical collaboration on the ground. 

“The Southeast has the research depth, industrial footprint, and collaborative spirit needed to lead in critical minerals innovation,” said Yuanzhi Tang, Georgia Power Professor in the School of Earth and Atmospheric Sciences, executive director of the Strategic Energy Institute, and founding director of the Center for Critical Mineral Solutions at Georgia Tech. “GEMs‑4 showed what’s possible when universities, industry, and government partners align around shared priorities.” 

Day one featured strategic dialogue on critical mineral resources, innovation pathways, and partnership models. A recurring theme was the co-production of critical minerals alongside major mineral commodities. “Many critical minerals are produced as byproducts of larger mining operations, making it essential to integrate recovery strategies into existing mineral industries rather than developing entirely new extraction systems,” noted Crawford Elliott, professor of geosciences at Georgia State University.

Day two transitioned to field‑based learning, led by Paul Schroeder, professor of geology at the University of Georgia. Participants visited active operations to better understand how regional industrial strengths can support national and international supply chain goals. Schroeder said, “Connecting people to the long-standing mineral extraction economy at the mining and plant sites, where the work gets done with an amazingly skilled workforce, underscores the unique role of Georgia’s place‑based capacity in advancing national and transatlantic supply chain goals.”

Organizers emphasized that resilient supply chains rely on regional capabilities built over time through university collaboration, industry partnerships, and community engagement. With three years of inter‑university coordination now underpinning the GEMS platform, the 2026 workshop demonstrated how the Southeast is contributing actionable models for U.S.-U.K. cooperation.

“Ecosystem-building at this scale requires participation from every part of the value chain, and we are encouraged by the model GEMs presents,” said Rachel Galloway, Consul General at British Consulate General Atlanta. “The collaboration across universities, industry, and government is exactly what enables long‑term impact on both sides of the Atlantic.”

Through focused dialogue and partnership-building, the symposium strengthened transatlantic collaboration, highlighted regional strengths, and accelerated innovation and translation across the critical minerals value chain, from resource characterization and processing to recycling, manufacturing, and deployment.

Though this scholarship is typically given to 50 exceptional incoming first-year students, a select few second- and third-year students are chosen to receive the honor for exemplifying the program’s pillars of scholarship, leadership, progress, and service.

“Annie and Madeline are exemplary campus leaders and will be able to build on their progress and service with the support of the Stamps Program. We are thrilled for the contributions they bring to the environmental science community,” says Linda Green, principal academic professional and interim director of the Environmental Sciences (ENVS) program.

About Annie Lin

Lin is a second-year ENVS major conducting undergraduate research on methane and natural gas in the Glass Research Group. Previous research highlights include quantifying microplastics in Georgia’s coastal water and working with a student group to publish the first publicly available data on microplastics pollution in the Chattahoochee River.

“I hope to build a career in environmental policy and justice — developing and implementing scientific, holistic, and equitable solutions to environmental issues and bridging the gaps between research, policy, and communities,” says Lin.

She is a student coordinator for Georgia Tech’s Center for Sustainable Communities Research and Education and the Georgia Tech student engagement and network coordinator for the United Nations Regional Centre of Expertise Greater Atlanta.

Why environmental science? 

“I was born and raised in Atlanta and grew up close to the Chattahoochee River,” explains Lin. “In high school, I was very involved with Chattahoochee Riverkeeper, including an 11-mile, eight-hour paddling cleanup; field and lab work to track bacterial contamination caused by sewage spills; and speaking to state legislators about environmental bills. These experiences taught me the importance of helping make the necessary systemic changes to address environmental issues.”

About Madeline Weller 

Weller is a second-year ENVS major working in the Tang Research Group, characterizing rare earth elements from Georgia kaolinite clay minerals for renewable energy applications. She also works on the Georgia Tech Methane Vertically Integrated Project to pioneer local methane measurements and in Georgia Tech’s Office of Sustainability to further sustainability efforts and outreach with Solar Stewards.

“Through experiences with Solar Stewards, I saw firsthand how community and rooftop solar can impact people, reducing their energy burden…,” says Weller. "Being at Georgia Tech has provided me with the resources and courage to act on my passion for achieving sustainability through energy equity, ensuring everybody has access to reliable and affordable electricity."

Outside of research, she is a member of Energy Club @ GT; Sigma Gamma Epsilon, the national honor society for the Earth Sciences;  Association of Environmental Engineers and Scientists; Photography @ GT; and Runnin’ Wreck.

Why environmental science?

“I chose environmental science because I was inspired to use my science skills to help find a solution to environmental issues, including climate change,” she explains. “Improving environmental conditions is not just important for biodiversity and ecosystems, but essential for human health and the longevity of future generations.”

“We certainly didn’t think of ourselves as pioneers,” says Whatley. “We were just trying to get through.”

Today, Whatley is no longer a hidden figure as she is now recognized for her trailblazing role.  She has been honored by the Institute’s Pathway of Progress art installation, Women of Distinction Award, and scholarship endowment established by the Georgia Tech Black Alumni Organization.

As Georgia Tech celebrates Women’s History Month, Whatley’s barrier-breaking legacy is a reminder of how women in STEM expand what’s possible, not only for themselves, but for those who follow.

Following the math path

Whatley grew up in Chubbtown, a self-sufficient Black community established pre-Civil War in Cave Spring, Georgia. The first Black valedictorian of Cave Spring High School after desegregation, she loved math from an early age. Whatley often tagged along with her father who was always building or fixing something — inspiring her to use numbers to solve problems.

She majored in math at Clark (now Clark Atlanta University), graduating magna cum laude. Encouraged to attend a predominantly white institution for graduate school by Joseph James Dennis, head of Clark’s Mathematics department, Whatley and Hammonds applied to Georgia Tech and Emory University. Tech responded first with an unexpected bonus: a teaching assistantship.

“Earning money to teach math and help pay for school appealed to me,” she shares.

Finding her footing at Tech

Entering the Institute as one of the few Black women on campus came with challenges. Whatley enrolled only nine years after Georgia Tech became the first university in the Deep South to admit African American students without a court order. 

“I’m not sure they wanted us there,” she admits. “But I wasn’t nervous. I was excited to learn more math — and teach it as well.”

As a graduate teaching assistant, Whatley taught undergraduate calculus, algebra, and trigonometry. Students were often surprised to see her at the front of the classroom, as most instructors were white males. She remembers professors who encouraged her, particularly her advisor Professor Emeritus Robert Kasriel.

“He believed in me, especially my knowledge of math,” Whatley says. “He encouraged me to speak up with confidence.”

Another professor pushed her to contest a grade he felt was unfair. She chose instead to stay focused on completing her degree. Despite the obstacles, Whatley remembers her time at Tech fondly. “I really enjoyed the classroom interaction with the undergraduates and teaching subjects I loved.”

She appreciates the toughness of the education she received. “Georgia Tech rewards tenacity. If you can make it through here, you can make it through just about anything — and that problem‑solving confidence stays with you.”

Choosing to serve

After graduation, Whatley joined BellSouth as a junior engineer, working on depreciation studies and writing early computer programs in Basic and Fortran.

“I took a class at Morehouse to learn programming. We used ticker tape, punch cards, and computers that took up an entire room,” remembers Whatley.  

She spent 22 years at BellSouth, earning frequent promotions. Her career shifted into a new direction when she heard a radio request for tutors at Marietta Junior High School. She volunteered and began working with several students, including a middle school girl who still counted on her fingers. Whatley guided her toward more confident problem-solving. “All she needed was someone to take the time to work with her.”s.

Tutoring became a catalyst for change. Motivated by the difference she could make, she left corporate America.

Expanding her impact

After obtaining certification from Mercer University, she became a high school math teacher. Whatley planned to teach for just three years but stayed for four after her advisement class of ninth graders begged her to stay until they graduated. 

Committed to expanding her impact, Whatley earned an educational specialist degree from the University of West Georgia and a Ph.D. in Educational Studies from Emory University. While at Emory, she began an educational consulting career,  launching Educational Dynamix, a nonprofit firm focused on learning and development for children and educators. Her consulting work also explored the connections between music and mathematics — helping educators and parents use both to strengthen student learning.

“Teaching math was satisfying,” says Whatley. “I enjoyed going into a class where students — or their teachers — didn’t believe in their ability to do math and showing them that they could do it.”

Whatley smiles and clarifies: “When I went into education, whether I was working with students, training teachers, or helping make changes in organizational structures, I found my passion. Looking back, hopefully, I made some lives better overall.”

 Sharing family history

Whatley’s influences are felt beyond the classroom. She is the author of several books, including The Chubbs: A Free Black Family’s Journey From the Antebellum Era to the Mid-1900s, which grew out of her family’s history. Whatley began this research while assisting with media features on her cousin, University of Georgia football star Nick Chubb.

Researching her family’s story led to a surprising discovery: a crumpled bill of sale for an enslaved girl that her son tucked into her grandmother’s old trunk. That document — and the stories surrounding it — propelled her to write the book and preserve Chubbtown’s history for future generations. 

Reflecting on a legacy

Whatley says faith and family are the most important things in her life. She has been married to her husband, Melvin, for 55 years. Her daughter, son, and several relatives also attended Georgia Tech, with her daughter running track and cross country and her son playing football. “We’re a Yellow Jacket family with one Bulldog granddaughter,” she says with a smile.

Today, Whatley is honored to have the recognition that came years after graduation. “What I went through wasn’t in vain. It feels good to know that I opened some doors and helped others along the way.”

As during previous editions, this year’s conference featured more than two dozen scientists, engineers, policy experts, and thought leaders from Georgia Tech and beyond, illustrating how collaboration across fields – from science and engineering to public policy and international affairs – helps to advance strategic research priorities. 

“Frontiers is about discovery and connections across disciplines and generations,” says Susan Lozier, dean of the College of Sciences and Betsy Middleton and John Clark Sutherland Chair. “This edition provided an inspiring glimpse into the future of space exploration and the many ways Georgia Tech is contributing to research and missions seeking answers to what lies beyond our planet.” 

Commitment to Space

Space research is a key institutional priority at Georgia Tech, which is home to numerous academic and research programs in planetary sciences, robotics, mission design, space policy, and other areas. 

The recently established Space Research Institute (SRI) serves as the central hub connecting the broad range of space-related research across campus. Led by Jud Ready, who also serves as principal research engineer at the Georgia Tech Research Institute, SRI has expanded support for space research and commercialization through initiatives such as the CreationsVC Space Fellows Program and Centers, Programs, and Initiatives seed grant program.

SRI’s efforts are in line with Georgia Tech’s long-standing contribution to space exploration. Hundreds of Yellow Jacket alumni work in the space sector, including several graduates who are playing key roles in the Artemis program. To date, more than a dozen Georgia Tech alumni have traveled to space.

Exploring the Final Frontier

The conference featured a series of panels and discussions led by faculty and researchers from the Colleges of Sciences and Engineering as well as the Ivan Allen College of Liberal Arts. 

Sessions explored how researchers are studying the processes and conditions that support planetary habitability, seeking to answer one of humanity’s greatest questions: Does life exist beyond Earth? Speakers also examined how analog fieldwork in Earth’s extreme environments can inform space exploration, and how space research, in turn, can deepen our understanding of our own world.

Additional conversations centered on building better space missions through improved understanding of team and individual resilience, data collection, navigation, and the development of advanced technologies like the robots developed through the NASA LASSIE Project. 

Frontiers also highlighted Georgia Tech’s commitment to preparing the next generation of space scientists, engineers, and leaders. Student training and engagement were recurring themes throughout the day, with speakers emphasizing opportunities for student-led and student-run missions and research. A panel of Georgia Tech alumni shared their own STEM career journeys, challenging the idea of “one right path” to success — and acknowledging the resources and opportunities available at the Institute. 

A highlight of the conference was a fireside chat with Atlanta-native, retired U.S. Army Colonel and NASA Astronaut R. Shane Kimbrough (M.S. Operations Research 1998). Kimbrough, who spent a total of 388 days in space and performed nine spacewalks across three missions, reflected on his career and the evolution of spaceflight. He emphasized the expanding role of public-private and international partnerships in advancing ambitious goals, such as creating a permanent human outpost on the Moon. 

Policy and Public

The conference also explored how policy influences space discovery and innovation, with discussions touching on such issues as space security, access, governance, sustainability — and the influence of technology and science fiction on public perception and policy. 

Panelists described current policy frameworks governing outer space as struggling to keep pace with rapidly advancing technologies and expanding activities. According to these experts, increasing tensions among commercial, research, and recreational uses of space call for greater coordination among private and government entities to balance competing priorities while maximizing opportunities for innovation and exploration. 

The conference was punctuated by a networking lunch connecting attendees with Atlanta’s public astronomy community – including partners at several universities and the Georgia Tech Astronomy Club, which set up telescopes for attendees to safely observe the sun. Later that evening, the Georgia Tech Observatory hosted its Public Night, welcoming the broader Atlanta community to campus for telescope views of Jupiter, the Orion Nebula, and other celestial bodies. 

The Observatory Night was a fitting conclusion to a full day focused on Georgia Tech’s commitment and contributions to inspiring future generations of space explorers through research, education, and outreach.

“Attending the 75th Lindau Nobel Laureate Meeting is both an honor and a responsibility: a chance to represent my academic community which focuses on the study of elusive particles called neutrinos while learning from those who have shaped the field,” says Papadopoulou, who will join Georgia Tech as a School of Physics assistant professor in August 2026. “I hope to come away with a deeper understanding of how transformative ideas emerge and how to cultivate the kind of leadership and vision needed to guide future large-scale scientific efforts that will unravel some of the mysteries of the universe.”

Papadopoulou obtained her Ph.D. in experimental physics from the Massachusetts Institute of Technology. As part of her research, she analyzed neutrino data collected by the MicroBooNE detector at Fermi National Accelerator Laboratory in Illinois and electron scattering data from the Jefferson Lab in Virginia. 

In 2022, she joined Argonne National Laboratory as a Maria Goeppert Mayer Fellow, continuing her research as a member of the MicroBooNE, Short-Baseline Near Detector, Deep Underground Neutrino Experiment, and Jefferson Lab’s Electrons-For-Neutrinos collaborations. Her work focuses on testing the performance of simulation predictions against existing and new neutrino and electron data sets. 

Papadopoulou currently serves as a J. Robert Oppenheimer Fellow at Los Alamos National Laboratory where she is working to better understand neutrino interactions.

Is the whole universe just a simulation? – Moumita B., age 13, Dhaka, Bangladesh

How do you know anything is real? Some things you can see directly, like your fingers. Other things, like your chin, you need a mirror or a camera to see. Other things can’t be seen, but you believe in them because a parent or a teacher told you, or you read it in a book.

As a physicist, I use sensitive scientific instruments and complicated math to try to figure out what’s real and what’s not. But none of these sources of information is entirely reliable: Scientific measurements can be wrong, my calculations can have errors, even your eyes can deceive you, like the dress that broke the internet because nobody could agree on what colors it was.

Because every source of information – even your teachers – can trick you some of the time, some people have always wondered whether we can ever trust any information.

If you can’t trust anything, are you sure you’re awake? Thousands of years ago, Chinese philosopher Zhuangzi dreamed he was a butterfly and realized that he might actually be a butterfly dreaming he was a human. Plato wondered whether all we see could just be shadows of true objects. Maybe the world we live in our whole lives inside isn’t the real one, maybe it’s more like a big video game, or the movie “The Matrix.”

The Simulation Hypothesis

The simulation hypothesis is a modern attempt to use logic and observations about technology to finally answer these questions and prove that we’re probably living in something like a giant video game. Twenty years ago, a philosopher named Nick Bostrom made such an argument based on the fact that video games, virtual reality and artificial intelligence were improving rapidly. That trend has continued, so that today people can jump into immersive virtual reality or talk to seemingly conscious artificial beings.

Bostrom projected these technological trends into the future and imagined a world in which we’d be able to realistically simulate trillions of human beings. He also suggested that if someone could create a simulation of you that seemed just like you from the outside, it would feel just like you inside, with all of your thoughts and feelings.

Suppose that’s right. Suppose that sometime in, say, the 31st century, humanity will be able to simulate whatever they want. Some of them will probably be fans of the 21st century and will run many different simulations of our world so that they can learn about us, or just be amused.

Here’s Bostrom’s shocking logical argument: If the 21st century planet Earth only ever existed one time, but it will eventually get simulated trillions of times, and if the simulations are so good that the people in the simulation feel just like real people, then you’re probably living on one of the trillions of simulations of the Earth, not on the one original Earth.

This argument would be even more convincing if you actually could run powerful simulations today, but as long as you believe that people will run those simulations someday, then you logically should believe that you’re probably living in one today.

Signs We’re Living in a Simulation …Or Not

If we are living in a simulation, does that explain anything? Maybe the simulation has glitches, and that’s why your phone wasn’t where you were sure you left it, or how you knew something was going to happen before it did, or why that dress on the internet looked so weird.

There are more fundamental ways in which our world resembles a simulation. There is a particular length, much smaller than an atom, beyond which physicists’ theories about the universe break down. And we can’t see anything more than about 50 billion light-years away because the light hasn’t had time to reach us since the Big Bang. That sounds suspiciously like a computer game where you can’t see anything smaller than a pixel or anything beyond the edge of the screen.

Of course, there are other explanations for all of that stuff. Let’s face it: You might have misremembered where you put your phone. But Bostrom’s argument doesn’t require any scientific proof. It’s logically true as long as you really believe that many powerful simulations will exist in the future. That’s why famous scientists like Neil deGrasse Tyson and tech titans like Elon Musk have been convinced of it, though Tyson now puts the odds at 50-50.

Others of us are more skeptical. The technology required to run such large and realistic simulations is so powerful that Bostrom describes such simulators as godlike, and he admits that humanity may never get that good at simulations. Even though it is far from being resolved, the simulation hypothesis is an impressive logical and philosophical argument that has challenged our fundamental notions of reality and captured the imaginations of millions.

This Thursday, April 2, the College of Sciences is hosting an inspiring look at the future of space exploration and life beyond Earth. Frontiers in Science: Advancing Space Exploration will convene leading scientists, engineers, policy experts, and thought leaders from across Georgia Tech and beyond to share research that’s guiding discovery and innovation. 

Published today in the journal Nature Communications, the paper “Trivalent Titanium in High-Titanium Lunar Ilmenite” confirms titanium in a reduced, trivalent state in a black, metal-rich lunar mineral called ilmenite. It’s a state only possible in low-oxygen environments, conditions researchers refer to as “reducing.”

“Models have suggested that these reducing conditions may have varied at different locations and times across the surface of the Moon,” says lead author Advik Vira, a graduate student in the School of Physics who recently earned his doctoral degree. “We hope our microscopy technique can be a valuable step in mapping and understanding the Moon’s 4.5-billion-year history.”

The team anticipates that their technique could be used on many of the lunar samples collected more than 50 years ago by the Apollo missions in addition to the Apollo Next Generation Samples — a group of lunar samples that have been stored under pristine conditions — and new samples from the planned Artemis missions, with Artemis II slated for launch this spring. The technique might also be applicable to samples collected from the far side of the Moon and returned in 2024 by the Chang’e-6 mission.

“The Moon holds clues not only to its own past, but also to the earliest eras of Earth’s evolution — history that has long since been erased from our planet,” Vira says. “This study is a step toward understanding the history of both and a reminder that there is still so much left to learn from the lunar rocks we’ve brought back to Earth.”

The School of Physics research team included corresponding authors Vira and Professor Phillip First; in addition to graduate student Roshan Trivedi; undergraduate students Gabriella Dotson, Keyes Eames, Dean Kim, and Emma Livernois; and Professor Zhigang Jiang, along with Institute for Matter and Systems Materials Characterization Facility Senior Research Scientist Mengkun Tian; School of Chemistry and Biochemistry Senior Research Scientist Brant Jones and Thom Orlando, Regents' Professor in the School of Chemistry and Biochemistry with a joint appointment in the School of Physics. 

The Georgia Tech team was joined by Addis Energy Senior Geochemist Katherine Burgess; Macalester College Assistant Professor of Geology Emily First; along with Lawrence Berkeley National Laboratory Research Scientist Harrison Lisabeth, Senior Scientist Nobumichi Tamura, and Postdoctoral Fellow Tyler Farr, who recently earned a Ph.D. from Georgia Tech’s George W. Woodruff School of Mechanical Engineering.

CLEVER research

The investigation began with a dark gray rock called a lunar basalt. Formed when ancient magma erupted on the Moon’s surface, minerals crystallized as it cooled — preserving key information in their structures. Billions of years later, the rock was brought to Earth by the 1972 Apollo 17 mission, where a small piece is now stored at Georgia Tech’s Center for Lunar Environment and Volatile Exploration Research (CLEVER), a NASA Solar System Exploration Research Virtual Institute (SSERVI) center led by Orlando.

As a NASA virtual institute, CLEVER supports researchers exploring lunar conditions and developing tools for the upcoming crewed Artemis missions, and provided the lunar samples for this research. The SSERVI also plays a critical role in training the next generation of planetary researchers: both Vira and Farr earned their Ph.D.s while on the CLEVER team.

“At CLEVER, we are very interested in understanding the impacts of space weathering,” Vira says. “We implemented modern sample preparation and advanced microscopy techniques to image samples at the atomic level, and were curious to apply it more broadly to the collection of Apollo rocks in the Orlando Lab. This sample caught our attention.”

“When we imaged an ilmenite crystal from the lunar basalt, what struck us first was how uniform and perfect the crystal structure was,” he recalls. “We found no defects from space weathering and instead saw an undamaged, pristine crystal — undisturbed for 3.8 billion years.”

To investigate further, the team analyzed small chips of the rock with Burgess, a member of the RISE2 SSERVI team and then a geologist at the U.S. Naval Research Laboratory. Using state-of-the-art electron microscopy and spectroscopy techniques, Vira determined the oxidation state of the elements in the ilmenite present. 

In spectroscopy measurements, each element leaves a distinct ‘signature,’ Vira explains. “When we brought our results back to Georgia Tech’s Materials Characterization Facility, Mengkun (Tian) noticed something unusual: the signature showed titanium might be present in the trivalent state.”

The presence of trivalent titanium had long been suspected in this lunar mineral. The team was intrigued. 

A new window into old rocks

With funding from Georgia Tech’s Center for Space Technology and Research (CSTAR), Vira returned to the U.S. Naval Research Laboratory to analyze additional samples. The results confirmed that more titanium was present than the mineral’s formula (FeTiO₃) predicts — indicating a portion of the titanium present was trivalent.

“That led me to place our measurements in terms of the broader geological context,” Vira shares. Working with First, Vira explored how ilmenite with trivalent titanium could help reconstruct the nature of ancient magmas from the Moon, especially the chemical availability of oxygen.

“Because its location on the Moon was noted during the Apollo mission, we know exactly where this rock is from, and we can determine how old the rock is,” he explains. “When coupled with our trivalent titanium measurements, we can use that information to estimate the reducing conditions for this specific region at the specific time our rock formed.”

If the upcoming Artemis missions return samples suitable for the team’s technique, these rocks could provide a new window into ancient lunar geology. The research also highlights that many lunar samples already on Earth could be reexamined to look for trivalent titanium.

“There is still so much to learn from the lunar samples we have already brought to Earth,” Vira says. “It’s a testament to the long-term value of each sample return mission. As technology continues to advance, this type of work will continue to give us critical insights into our planet and our place in the universe for years to come.”

Funding: This work was directly supported by the NASA SSERVI under CLEVER. Researchers were also supported by the NASA RISE2 SSERVI and the Heising-Simons Foundation. Funding for collaborations between the U.S. Naval Research Laboratory and Georgia Tech for the investigation of lunar minerals was provided by the Georgia Tech Center for Space Technology and Research. Sample preparation was performed at the Georgia Tech Institute for Matter and Systems, which is supported by the National Science Foundation. This work utilized the resources of the Advanced Light Source, a user facility supported by the U.S. Department of Energy, Office of Science, Office of Basic Energy Sciences, and was supported in part by previous breakthroughs obtained through the Laboratory Direct.

Amino acids also play a critical role commercially where they are manufactured and added to pharmaceuticals, dietary supplements, cosmetics, animal feeds, and industrial chemicals — an energy-intensive process leading to greenhouse gas emissions, resource consumption, and pollution.

A landmark new system developed at Georgia Tech could lead to an alternative: a commercially scalable, environmentally sustainable method for amino acid production that is carbon negative, using more carbon than it emits.

The breakthrough builds on a method that the team pioneered in 2024 and solves a key issue – increasing efficiency to an unprecedented 97% and reducing the bioprocess cost by over 40%. It’s the highest reported conversion of CO2 equivalents into amino acids using any synthetic biology system to date.

Published in the journal ACS Synthetic Biology, the study, “Cell-Free-Based Thermophilic Biocatalyst for the Synthesis of Amino Acids From One-Carbon Feedstocks,” was led by Bioengineering Ph.D. student Ray Westenberg and Professor Pamela Peralta-Yahya, who holds joint appointments in the School of Chemistry and Biochemistry and School of Chemical and Biomolecular Engineering. The team also included Shaafique Chowdhury (Ph.D. ChBE 25) and Kimberly Wennerholm (ChBE 23); alongside University of Washington collaborators Ryan Cardiff, then a Ph.D. student and now a Chain Reaction Innovations Fellow at Argonne National Laboratory, and Charles W. H. Matthaei Endowed Professor in Chemical Engineering James M. Carothers; in addition to Pacific Northwest National Laboratory Synthetic Biology Team Leader Alexander S. Beliaev.

"This work shifts the narrative from simply reducing carbon emissions to actually consuming them to create value,” says Peralta-Yahya. “We are taking low-cost carbon sources and building essential ingredients in a truly carbon-negative process that is efficient, effective, and scalable.”

Heat-Loving Organisms

The work builds on the cell-free technology the team used in their earlier study. “Previously, we discovered that a system that uses the machinery of cells, without using actual living cells, could be used to create amino acids from carbon dioxide,” Peralta-Yahya explains. “But to create a commercially viable system, we needed to increase the system’s efficiency and reduce the cost.”

The team discovered that bits of leftover cells were consuming starting materials, and — like a machine with unnecessary gears or parts — this limited the system’s efficiency. To optimize their “machine,” the team would need to remove the extra background machinery.

"Leftover cell parts were using key resources without helping produce the amino acids we were looking for,” says Peralta-Yahya. “We knew that heating the system could be one way to purify it because heat can denature these components.”

The challenge was in how to protect the essential system components from the high temperatures, she adds. “We wondered if introducing enzymes produced by a heat-loving bacterium, Moorella thermoacetica, might protect our system, while still allowing us to denature and remove that inefficient background machinery.”

The results were astounding: after introducing the enzymes, heating and “cleaning” the system, and letting it cool to room temperature, synthesis of the amino acids serine and glycine leaped to 97% yield — nearly three times that of the team’s previous system.

Scaling for Sustainability

To make the system viable for large-scale use, the team also needed to reduce costs. “One of the most costly components in this system is the cofactor tetrahydrofolate (THF),” Peralta-Yahya shares. “Reducing the amount of THF needed to start the process was one way to make the system more inexpensive and ultimately more commercially viable.”

By linking reaction steps so waste from one step fueled the next, the team devised a method to recycle THF within the system that reduces the amount of THF needed by five-fold — lowering bioprocessing costs by 42%.

“This decrease in cost and increase in yield is a critical step forward in creating a method with real potential for use in industry and manufacturing,” Peralta-Yahya says. “This system could pave the way for moving this carbon-negative technology out of the lab and onto the continuous, industrial scale."

The event began with a luncheon for College of Sciences’ faculty and staff where representatives from GTRI provided an overview of its mission and research areas.

“The better our faculty and staff understand GTRI, the better we can support students interested in pursuing careers there,” says James Stringfellow, career education program manager at the College of Sciences, who organized the event.

Stringfellow welcomed attendees and thanked GTRI for creating meaningful opportunities for students. He also emphasized the value of the growing pipeline between the College and GTRI.

Following the luncheon, GTRI recruiters met one‑on‑one with students to discuss available positions and the best methods to find and apply for GTRI research roles.

The event concluded with a GTRI panel featuring Jeremy Brown, director of education and outreach; Eric Klein, senior research associate; and Thomas Martin, (EE 91), chief scientist. The panelists highlighted its broad range of positions and encouraged students to consider internships, co-ops, and long‑term career paths at GTRI.

“We hire around 500 students a year, and many earn security clearances,” explains Brown. “We want students to get connected to GTRI early and understand our mission. Talk to us about your research projects and how you want to contribute.”

Students who attended said the panel’s conversational format helped them better understand how their academic work can translate into research careers.

“The atmosphere was great — more of a conversation than a lecture. I liked that it was tailored for students who are interested in research,” says Txaber Treviño, a first‑year aerospace engineering major.

“I came because I was interested in careers where I can apply a science degree,” shares Aryan Bhakta, a first‑year biology major. “GTRI is a great example of a place where researchers can make a difference.”

Panelists emphasized the GTRI’s mission‑driven work and the importance of curiosity, persistence, and hands‑on experience.

“The work done at GTRI is important,” says Martin. “As a university-affiliated research center, we work on emerging technologies that serve a higher purpose. It’s an exciting and fulfilling place to work.”

Klein encouraged students to explore opportunities early in their academic careers. “Use your co-ops, internships, or research jobs on campus to prepare for a future aligned with what you are passionate about,” he says. “And if you have trouble finding a research position in your area of interest, go to a professor or volunteer. That really stands out on a résumé.”

GTRI Day is part of the College of Sciences Career Education event series. The Students and Alumni Leadership Dinner on Wednesday, April 8th, will close out the semester's events.

But as carbon removal grows, so does a core problem: The carbon removal industry is largely unregulated, particularly for more novel technologies without long-standing norms around reporting and verification. In today’s “voluntary carbon market,” a private company can claim it removed a certain amount of carbon, list that amount for sale, and allow another company to buy it to offset its emissions — with little independent oversight or transparency.

A new Nature NPJ Climate Action article argues that this system isn’t enough to meet global climate goals, and could even end up causing harm. In the paper, Chris Reinhard, Georgia Power Chair and associate professor in Georgia Tech’s School of Earth and Atmospheric Sciences, and Noah Planavsky of the Yale Center for Natural Carbon Capture call for a fundamental shift: Carbon removal should be quantifiable, economically viable, and pursued in ways that create benefits for local communities — and greater transparency in carbon removal practice is necessary.

“We argue that it’s important to understand and quantify carbon removal practices that can benefit local communities, like better crop yields, and that this understanding is really only possible if these practices are pursued transparently,” Reinhard said. “The data used to quantify carbon removal and how much it costs need to be transparent — the surest route toward learning what works and building public trust in carbon removal as a solution.”

Transparency Trouble

Reinhard and Planavsky bring a unique technical and policy perspective to the issue. As geochemists, they study how Earth’s chemical composition and geological processes control the carbon cycle. Reinhard also co-founded a carbon removal startup he has since divested from. That insider experience and academic background helped them see the disconnect between what’s technologically possible and what market logic culturally or commercially incentivizes.

Today’s carbon removal startups often guard their methods and data as proprietary intellectual property. Without regulatory requirements or pressure from corporate carbon buyers, these startups have little reason to disclose carbon accounting practices, cost structures, or actual long-term impacts. The researchers argue that policy guidance and advocacy are needed to shift the industry toward meaningful openness.

“Our expertise is most firmly grounded in the technical dimensions of these carbon removal processes,” Reinhard said, “but we saw an opportunity here to push for better policy and start this dialogue about what transparency really means, in part to foster more public debate about what carbon removal ought to be doing for society.”

Community Beyond Carbon

The authors also stress that carbon removal should deliver benefits beyond atmospheric cleanup that communities can see and advocate for. For example, liming, or adding limestone to soil, can remove carbon while also improving crop yields and reducing erosion. Coastal ecosystem restoration can sequester carbon while strengthening shorelines and supporting fisheries. Georgia Tech’s own direct air capture work builds community engagement into the process to ensure that carbon removal is equitable. 

Reinhard and Planavsky say the next best step for the carbon removal industry is to identify which removal pathways offer the clearest benefits, what they cost, and where transparency gaps are most damaging. This foundation will help create policies that make carbon removal reliable, verifiable, and community-centered. 

Without oversight, they argue, carbon removal risks remaining a niche, market-defined practice — when the climate challenge demands a trusted, scalable, and democratically governed solution.

“This first set of CreationsVC Fellows offers an exciting cross-section of innovative hardware and software technologies built on Georgia Tech’s legacy of space exploration, hardware development, and product commercialization,” said Jud Ready, SRI executive director. 

In the first year of the three-year program, CreationsVC provides $125,000 to promote and accelerate innovations that have both space and terrestrial applications. The series offers participants training focused on customer discovery, engaging and compelling storytelling, value proposition design and quantification, and lean/agile project/product management.

“CreationsVC is centered on a deep appreciation for innovation and big thinking,” said Steve Braverman, co-founder and managing partner of CreationsVC. “We felt this was the right time to align our efforts in sourcing and supporting dual-value technologies that will have an impact on both Earth and space.” 

The six startups tackle real-world space research problems like supply chain management, how artificial intelligence works in space, and navigation.

“We are excited CreationsVC is providing us with an opportunity to try new approaches to accelerate deep tech development,” said Jonathan Goldman, Quadrant-i’s director. “These are the toughest kinds of startups to build, and we look forward to the learning we will gain from forcing our innovators out of their comfort zones to embrace some new and valuable skills.”

Meet the cohort:
 

Company: CIMTech.ai
 

Founders: Shimeng Yu, James Read

School: School of Electrical and Computer Engineering (ECE)

Objective: To develop energy-efficient, radiation-tolerant artificial intelligence processors using a persistent type of ferroelectric memory. The startup aims to improve applications requiring high power efficiency, such as battery-powered devices and space-based systems.

Why Q-i: “The advantage of Q-i is in helping technical founders turn their research into products that solve customers’ problems,” noted James Read. “For us, that means talking with potential customers and hearing their pain points directly from the source. Now we’re use that information to build a convincing narrative around our startup’s value for stakeholders and investors.” 

Company: SkyCT
 

Founders: Morris Cohen, Matthew Strong

School: ECE

Objective: To provide up-to-date mapping of the electrical properties of the upper atmosphere, with applications to GPS-free navigation, long-range communication, and satellite and launch vehicle viability. The startup uses the radio energy released by lightning strikes to create this map. 

Why Q-i: “This weird region about 50 miles up from Earth’s surface is both really hard to track and measure, and also impacts a surprising array of applications,” said Cohen. “It’s sometimes called the `ignorosphere’ because of how difficult it is to measure, and it’s time we change that.”

They have also guided me through the process of obtaining funding through the Georgia Research Alliance for our commercialization effort.”

“Four minutes is too long.”

That’s the note undergraduate Chris Zuo sent me along with photos of countless mosquito bites on his bare skin. This full-body massacre wasn’t the result of a camping trip gone awry. He’d spent that limited amount of time in a room with 100 hungry mosquitoes while wearing nothing but a mesh suit we thought would have protected him.

Thus began our three-year journey trying to understand the behavior of a deceivingly simple insect, the mosquito. It may sound like a professor’s sadistic plan, but, really, we did everything by the book. Our university’s institutional review board approved our procedures, making sure Chris was safe and not coerced in any way. The mosquitoes were disease-free and native to our home state of Georgia. And this session resulted in the first and last bites anyone received during the study.

Besides my role as torturer of students, I am an author and professor at Georgia Tech with over 20 years of experience studying the movement of animals.

Mosquitoes are the world’s most dangerous animal. The diseases they carry, from malaria to dengue, cause over 700,000 deaths per year. More people have died from mosquitoes than wars.

The world spends US$22 billion per year on billions of liters of insecticides, millions of pounds of larvicides, and millions of insecticide-treated bed nets – all to fight a tiny insect that weighs 10 times less than a grain of rice and has only 200,000 neurons.

Yet, people are losing the war on mosquitoes. These insects are evolving to thrive in cities and spreading disease more rapidly with climate change. How can such simple animals find us so easily?

Scientists know mosquitoes have terrible eyesight and depend on chemical cues to make up for it. Knowing what attracts a mosquito, though, isn’t enough to predict its behavior. You can know a heat-seeking missile is drawn to heat, but you still won’t know how a missile works.

Enter Chris and his self-sacrifice in the mosquito room. By tracking the flight of many mosquitoes around him, we hoped to determine how they made decisions in response to his presence. Understanding how mosquitoes respond to humans is a first step to controlling them.

How Mosquitoes Zero In On Their Meal

Out of 3,500 species of mosquitoes, over 100 species are classified as anthropophilic, meaning they prefer humans for lunch. Certain species of mosquitoes will find the one person among a whole herd of cattle in order to suck human blood.

This is quite a feat considering mosquitoes are weak flyers. They stop flying in a slight 2-3 mph breeze, the same air speed generated by a horse’s swinging tail. In calmer conditions, mosquitoes use their minuscule brains to follow human heat, moisture and odors that are carried downwind.

Carbon dioxide, the byproduct of respiration of all living animals, is particularly attractive. Mosquitoes notice carbon dioxide as well as you notice the stink of a full dumpster, detecting it up to 30 feet (9 meters) away from a host, where concentrations dip to a few parts per million, like a few cups of dye in an Olympic-size pool.

Mosquitoes’ vision isn’t much help as they hunt for their next blood meal. Their two compound eyes have several hundred individual lenses called ommatidia, each about the width of a human hair. They produce a somewhat blurry mosaic or pixelated image. Due to the laws of optics, mosquitoes can discern an adult-size human only at a few meters away. With their vision alone, they cannot distinguish a human from a small tree. They inspect every dark object.

Gathering the Flight-Path Data

The challenge with studying mosquito flight is that, like trash-talking teenagers, most of what they do is meaningless noise. Mosquitoes flying in an empty room are largely making random changes in flight speed and direction. We needed many flight trajectories to cut through the noise.

One of our collaborators, University of California, Riverside, biologist Ring Cardé, told us that back in the 1980s, scientists conducted “bite studies” by stripping down to their underwear and slapping the mosquitoes that landed on their naked bodies. He said nudity prevented confounding variables, such as the color of a shirt’s fabric.

Chris and I looked at each other. Sit naked and wait to become mosquito prey? Instead, we designed the mesh suit that Chris originally wore into the mosquito room. But after seeing Chris’ bites, we needed a better way.

Instead, Chris washed long-sleeved clothes in unscented detergent and wore gloves and a face mask. Fully protected, Chris only had to stand and wait, while a cloud of mosquitoes swarmed him.

The U.S. Centers for Disease Control and Prevention introduced us to the Photonic Sentry, a camera that simultaneously tracks hundreds of flying insects in a room. It records 100 frames per second at 5 mm resolution for a space like a large studio apartment. In just a few hours, Chris and another graduate student, Soohwan Kim, generated more mosquito flight data than had previously been measured in human history.

Jörn Dunkel, Chenyi Fei and Alex Cohen, our mathematician collaborators at MIT, told us that the geometry of Chris’ body was still too complicated to study the mosquitoes’ reactions. Mathematicians excel at simplifying complex problems to their essence. Chenyi suggested we go easy on Chris – why not replace him with a simple dummy: a black Styrofoam ball on a stick combined with a canister of carbon dioxide.

Over the next two years, Chris filmed the mosquitoes circling the Styrofoam dummies mercilessly. Then he vacuumed up the mosquitoes, trying not to get bitten.

Deciphering the Trajectories

A mosquito flies like you would an airplane: it turns left or right, accelerates or hits the brakes. We determined a mosquito’s flight behavior as a function of its speed, location and direction with respect to the target as the first step in creating our model of their behavior.

Our confidence in our behavioral rules increased as we read more trajectories, ultimately using 20 million mosquito positions and speeds. This idea of incorporating observations to support a mathematical hypothesis is a 200-year-old idea called Bayesian inference. We illustrated the mosquito behavior we’d observed in a web application.

Using our model, we showed how different targets cause mosquitoes to fly differently. Visual targets cause fly-bys, where mosquitoes fly past the target. Carbon dioxide causes double takes, where mosquitoes slow down near the target. The combination of a visual cue and carbon dioxide creates high-speed orbiting patterns.

Up until now, we had used only experiments with Styrofoam spheres to train our model. The true test was whether it could predict mosquito flights around a human. Chris returned to the chamber, this time wearing all white clothes and a black hat, turning himself into a bull’s-eye. Our model successfully predicted the distribution of mosquitoes around him. We identified zones of danger, where there was a high chance of a mosquito circling around him.

Predicting mosquito behavior is a first step toward outsmarting them. In mosquito-prone areas, people design houses with features to prevent mosquitoes from following human cues and entering. Similarly, mosquito traps suck in mosquitoes when they get too close but still allow between 50% and 90% of mosquitoes to escape. Many of these designs are based on trial and error. We hope that our study provides a more precise tool for designing methods for mosquito capture or deterrence.

When Chris’ mother attended his master’s degree defense, I asked her how she felt about her son using himself as bait for mosquitoes. She said she was very proud. So am I – and not just because I’m relieved Chris didn’t ask me to take his place in the mosquito chamber.

Your DNA is continually damaged by sources both inside and outside your body. One especially severe form of damage called a double-strand break involves the severing of both strands of the DNA double helix.

Double-strand breaks are among the most difficult forms of DNA damage for cells to repair because they disrupt the continuity of DNA and leave no intact template to base new strands on. If misrepaired, these breaks can lead to other mutations that make the genome unstable and increase the risk of many diseases, including cancer, neurodegeneration and immunodeficiency.

Cells primarily repair double-strand breaks by either rejoining the broken DNA ends or by using another DNA molecule as a template for repair. However, my team and I discovered that RNA, a type of genetic material best known for its role in making proteins, surprisingly plays a key role in facilitating the repair of these harmful breaks.

These insights could not only pave the way for new treatment strategies for genetic disorders, cancer and neurodegenerative diseases, but also enhance gene-editing technologies.

Sealing a Knowledge Gap in DNA Repair

I have spent the past two decades investigating the relationship between RNA and DNA in order to understand how cells maintain genome integrity and how these mechanisms could be harnessed for genetic engineering.

A long-standing question in the field has been whether RNA in cells helps keep the genome stable beyond acting as a copy of DNA in the process of making proteins and a regulator of gene expression. Studying how RNA might do this has been especially difficult due to its similarity to DNA and how fast it degrades. It’s also technically challenging to tell whether the RNA is directly working to repair DNA or indirectly regulating the process. Traditional models and tools for studying DNA repair have for the most part focused on proteins and DNA, leaving RNA’s potential contributions largely unexplored.

My team and I were curious about whether RNA might actively participate in fixing double-strand breaks as a first line of defense. To explore this, we used the gene-editing tool CRISPR-Cas9 to make breaks at specific spots in the DNA of human and yeast cells. We then analyzed how RNA influences various aspects of the repair process, including efficiency and outcomes.

We found that RNA can actively guide the repair process of double-strand breaks. It does this by binding to broken DNA ends, helping align sequences of DNA on a matching strand that isn’t broken. It can also seal gaps or remove mismatched segments, further influencing whether and how the original sequence is restored.

Additionally, we found that RNA aids in double-strand break repair in both yeast and human cells, suggesting that its role in DNA repair is evolutionary conserved across species. Notably, even low levels of RNA were sufficient to influence the efficiency and outcome of repair, pointing to its broad and previously unrecognized function in maintaining genome stability.

RNA in Control

By uncovering RNA’s previously unknown function to repair DNA damage, our findings show how RNA may directly contribute to the stability and evolution of the genome. It’s not merely a passive messenger, but an active participant in genome maintenance.

These insights could help researchers develop new ways to target the genomic instability that underlies many diseases, including cancer and neurodegeneration. Traditionally, treatments and gene-editing tools have focused almost exclusively on DNA or proteins. Our findings suggest that modifying RNA in different ways could also influence how cells respond to DNA damage. For example, researchers could design RNA-based therapies to enhance the repair of harmful breaks that could cause cancer, or selectively disrupt DNA break repair in cancer cells to help kill them.

In addition, these findings could improve the precision of gene-editing technologies like CRISPR by accounting for interactions between RNA and DNA at the site of the cut. This could reduce off-target effects and increase editing precision, ultimately contributing to the development of safer and more effective gene therapies.

There are still many unanswered questions about how RNA interacts with DNA in the repair process. The evolutionary role that RNA plays in maintaining genome stability is also unclear. But one thing is certain: RNA is no longer just a messenger, it is a molecule with a direct hand in DNA repair, rewriting what researchers know about how cells safeguard their genetic code.

Have you ever noticed how a particular song can bring back a flood of memories? Maybe it’s the tune that was playing during your first dance, or the anthem of a memorable road trip.

People often think of these musical memories as fixed snapshots of the past. But recent research my team and I published suggests music may do more than just trigger memories – it might even change how you remember them.

I’m a psychology researcher at the Georgia Institute of Technology. Along with my mentor Thackery Brown and University of Colorado Boulder music experts Sophia Mehdizadeh and Grace Leslie, our recently published research uncovered intriguing connections between music, emotion and memory. Specifically, listening to music can change how you feel about what you remember – potentially offering new ways to help people cope with difficult memories.

Music, stories and memory

When you listen to music, it’s not just your ears that are engaged. The areas of your brain responsible for emotion and memory also become active. The hippocampus, which is essential for storing and retrieving memories, works closely with the amygdala, the brain’s emotional center. This is partly why certain songs are not only memorable but also deeply emotional.

While music’s ability to evoke emotions and trigger memories is well known, we wondered whether it could also alter the emotional content of existing memories. Our hypothesis was rooted in the concept of memory reactivation – the idea that when you recall a memory, it becomes temporarily malleable, allowing new information to be incorporated.

We developed a three-day experiment to test whether music played during recall might introduce new emotional elements into the original memory.

On the first day, participants memorized a series of short, emotionally neutral stories. The next day, they recalled these stories while listening to either positive music, negative music or silence. On the final day, we asked participants to recall the stories again, this time without any music. On the second day, we recorded their brain activity with fMRI scans, which measure brain activity by detecting changes in blood flow.

Our approach is analogous to how movie soundtracks can alter viewers’ perceptions of a scene, but in this case, we examined how music might change participants’ actual memories of an event.

The results were striking. When participants listened to emotionally charged music while recalling the neutral stories, they were more likely to incorporate new emotional elements into the story that matched the mood of the music. For example, neutral stories recalled with positive music in the background were later remembered as being more positive, even when the music was no longer playing.

Even more intriguing were the brain scans we took during the experiment. When participants recalled stories while listening to music, there was increased activity in the amygdala and hippocampus – areas crucial for emotional memory processing. This is why a song associated with a significant life event can feel so powerful – it activates both emotion- and memory-processing regions simultaneously.

We also saw evidence of strong communication between these emotional memory processing parts of the brain and the parts of the brain involved in visual sensory processing. This suggests music might infuse emotional details into memories while participants were visually imagining the stories.

Musical memories

Our results suggest that music acts as an emotional lure, becoming intertwined with memories and subtly altering their emotional tone. Memories may also be more flexible than previously thought and could be influenced by external auditory cues during recall.

While further research is needed, our findings have exciting implications for both everyday life and for medicine.

For people dealing with conditions such as depression or PTSD, where negative memories can be overwhelming, carefully chosen music might help reframe those memories in a more positive light and potentially reduce their negative emotional impact over time. It also opens new avenues for exploring music-based interventions in treatments for depression and other mental health conditions.

On a day-to-day level, our research highlights the potential power of the soundtrack people choose for their lives. Memories, much like your favorite songs, can be remixed and remastered by music. The music you listen to while reminiscing or even while going about your daily routines might be subtly shaping how you remember those experiences in the future.

The next time you put on a favorite playlist, consider how it might be coloring not just your current mood but also your future recollections as well.

Walking down the stairs in the Clough Undergraduate Learning Commons, you might look up to discover a set of letters made out of construction paper. Backlit by blue and red light, it reads, “Plant Library: Fridays 3:30 – 4:30”. This sign has caught the eye of many students, who walk inside to discover a bustling scene. Instead of books lining shelves, plants of all sorts are gathered in the windows, drinking in the sunlight. A group of students browses for a few moments before leaving with a plant of their own to nurture. The majority are gathered around a table, cutting up English ivy to propagate in recycled containers.   

If you’ve walked the aisles of a grocery store, scrolled through social media, watched television, or set foot in a fast-casual restaurant chain in recent months, you know that protein is having its moment.  

Historically, most engineers believed the former, using heterogeneities, or differences, in materials to make materials stronger and more resilient. However, research from Georgia Tech is showing that, in some cases, heterogeneities make materials weaker and can even accelerate cracks. 

Led by School of Physics Assistant Professor Itamar Kolvin, the study, “Dual Role for Heterogeneity in Dynamic Fracture,” was published in Physical Review Letters this fall. 

While Kolvin’s work is theoretical, the results of the research are widely applicable. “Predicting this type of toughening effect helps engineers decide how much reinforcement to add to a material, and the best way to do so,” he says. “Cracks are complex — they interact with the material, change shape, and respond dynamically. All of this affects the overall toughness, which impacts safety.”

Building Strong Materials

The study found that the key to crack behavior starts at the microscopic level where the material’s microscopic structure influences how it resists cracks running at different speeds.

“Cracks propagate by breaking bonds, and that costs energy,” he explains. “On top of this, materials experience extreme deformations close to where the crack runs, which costs additional energy. In some materials, the amount of this energy cost can depend on the crack’s speed because of microscopic friction between molecules.”

Other materials, like window glass, are mostly indifferent to the crack speed. These materials are made of simple molecules, allowing a crack to propagate slowly or quickly using the same amount of energy. The researchers found that including heterogeneities can help strengthen these materials.

Materials made of more complex molecules, like polymer plastics and gels, on the other hand, are velocity dependent: it takes more energy for a crack to propagate faster. In these materials, heterogeneities are less effective at toughening, and if the crack is fast enough, heterogeneities could help it advance. “That’s something we didn’t expect when we started,” Kolvin says.

Disorder Versus Design

After discovering which types of materials can benefit from heterogeneities, Kolvin wanted to investigate the best way to add them. “Natural materials like rocks are usually very messy and disordered,” he explains, “but in engineering, heterogenous materials tend to be patterned.” For example, imagine a manufactured material: heterogeneities may be added in a grid-like or other patterned way. Now, contrast that with the irregular freckles and inclusions you might see in a rock found in a streambed.

Kolvin’s question was simple: which material was stronger? The results, again, were surprising. The disordered case — similar to what is found in nature — created the toughest material. 

Among the patterned materials the team tested, only one was as tough as the disordered case — and every other pattern tested made the material weaker.

From Lab to Landscape

At Georgia Tech, Kolvin’s lab focuses on the mechanics of materials — both solid and fluid. “We are using our expertise in physics to explore questions across different fields,” he says. “A common concept is treating materials as continua — zooming out from molecular detail to look at how materials deform and flow at the large scale.”

This current research follows suit with applications ranging from investigating the smallest material microstructures to predicting earthquake fractures. “Earthquake faults are highly disordered, and simulating these ruptures is a major challenge, usually requiring supercomputers to solve crack propagation in three dimensions,” Kolvin says. “But with the tools our study has developed, we can simulate similar conditions and large systems using just a desktop computer.”

“This opens the doors for scientists, engineers, physicists, and geologists to explore problems right from their own computer, allowing more researchers access to more tools,” he adds. “And new tools often lead to new discoveries.”

The new initiative was sparked by ongoing research at Georgia Tech — and a Yellow Jacket connection: when Postdoctoral Research Fellow Hannah Youngblood’s work on exfoliation glaucoma (XFG) was featured by the BrightFocus Foundation, it caught the attention of Jennifer Rucker, an Alabama resident who was diagnosed with XFG several years ago.

Excited that the research could change outcomes for people like her — and proud that it’s happening at her husband Philip Rucker’s, EE 72, alma mater — Jennifer Rucker reached out to Youngblood and her advisor, School of Chemistry and Biochemistry Professor and Kelly Sepcic Pfeil, Ph.D. Chair Raquel Lieberman. 

“As the wife of a Georgia Tech graduate and an individual with pseudoexfoliation glaucoma, I was inspired to support the scientists whose efforts may help me and others,” Jennifer Rucker says. What followed was a meaningful dialogue and a shared sense of purpose — and the creation of the Georgia Tech Glaucoma Research Fund (Wreck Glaucoma! Fund). 

“It meant so much that Jennifer took the initiative to reach out to learn more about our research,” says Lieberman. “Moments like this remind me how deeply meaningful it is to connect with people in the broader community who are navigating glaucoma. Opportunities for such personal connections are rare, but they inspire and further motivate us to achieve our lab’s mission to improve the lives of individuals suffering from blindness diseases.”

A Personal Connection

Youngblood’s interest in glaucoma research also stems from a personal connection: her father was diagnosed with glaucoma as a young adult. Now, Youngblood studies the genetic and molecular factors behind XFG in the Lieberman research lab. 

“XFG is an aggressive form of the disease with no known cure,” Youngblood says. While scientists know that XFG is the result of abnormal accumulation of proteins in the eye, current treatments only address symptoms rather than treating the root cause of the disease.

“We know XFG is driven by protein buildup, but we still don’t know why it happens,” she explains. “My work studying specific genetic variants aims to uncover this.” 

The Genetics of Glaucoma

In particular, Youngblood is researching the role of LOXL1, a protein that plays a role in soft tissue throughout the body, including the eyes.

“Research has shown that people with variants in the genes responsible for this protein are more likely to have XFG,” she says. “That made me curious to see if the variants might be impacting the structure of the LOXL1 protein itself and how those variants might lead to disease.”

Youngblood is currently testing her theory in the lab. “My hope is that new insight into proteins like LOXL1 will bring us closer to treatments that address XFG at its source,” she says. “The new Georgia Tech Glaucoma Research Fund is a tremendous step forward in making that hope a reality.”

He joins the ranks of nearly 50 faculty from Georgia Tech who have received Sloan Research Fellowships, including School of Mathematics’ Alex Blumenthal in 2024, Hannah Choi in 2022, Yao Yao in 2020, Konstantin Tikhomirov in 2019, Lutz Warnke in 2018, Zaher Hani in 2016, Jen Hom in 2015, and Greg Blekherman in 2012; School of Chemistry and Biochemistry's Vinayak Agarwal in 2018; School of Earth and Atmospheric Sciences' Christopher Reinhard in 2015; and School of Physics’ Chunhui (Rita) Du in 2024 and Tamara Bogdanović in 2013. 

Freeman joined the Institute in 2023 and was also recently named a 2024 Packard Fellow by the David and Lucile Packard Foundation and 2025 Early Career Fellow by the Ecological Society of America.

Understanding the ‘escalator to extinction’

Known for his groundbreaking research in climate change and bird ecology, Freeman studies birds worldwide from Appalachia to Ecuador. He specializes in tropical populations where his work is centered on understanding how mountain species respond to a changing climate — and how to facilitate their survival. 

“Tropical mountains are some of Earth’s largest biodiversity hotspots; they harbor an extraordinary number of species,” shares Freeman. “Additionally, tropical mountain birds are particularly sensitive to environmental change, so they can serve as an early warning system for global conservation efforts.”

Previously, his research has shown that some species are on an ‘escalator to extinction’ with vulnerable groups moving to higher elevations to escape warming temperatures. At the top of the escalator, some summit-dwelling species are disappearing. 

“We know that many species are on this escalator,” Freeman says. “The next step is to figure out which species are most vulnerable and why. In order to direct conservation efforts, we need to know who is vulnerable, why small increases in temperature have dramatic effects, and what can be done to help.”

A worldwide early warning system

To uncover those answers, Freeman is taking two approaches: mapping global patterns with big picture data and conducting on-the-ground research in the tropics.

To target the former, he created the Mountain Bird Network, which supports community scientists in conducting bird surveys on their local mountains. The goal is to create a system that allows researchers to diagnose vulnerable species before they are too sparse to save.

“When a species is in trouble, we need to know as soon as possible,” Freeman says. “Once a population is small enough to be at risk of extinction, it’s very hard to reverse that process. The Mountain Bird Network collects data on mountain bird abundances and distributions across the globe, which, when used with data from a global citizen science program called eBird, can be leveraged to build models to identify which species might be vulnerable before those populations become critically small.”

A living lab on Tech Mountain

Freeman’s other avenue of research involves building an ambitious living laboratory in Pinchincha, Ecuador. The research site will span thousands of meters along the flanks of a local mountain, spanning lowland rainforest, foothill rainforest, and cloud forest ecosystems.

“The mountain is home to thousands of birds from hundreds of species,” Freeman says. “My goal is to track and understand their daily lives — and how climate changes impact them.”

Using cutting-edge tracking technology, he will tag and monitor their daily movements, mapping those against microclimate sensors placed at different elevations along the mountain’s slopes. The challenge of placing and maintaining thousands of tiny sensors in rugged conditions means that it has never been done before.

“We’ll track these birds for at least five years –- but hopefully for decades,” Freeman says. “The data we gather at Tech Mountain will be the first of its kind, and my hope is that it makes a real difference in conservation efforts worldwide.”

The project, inspired by an Atlanta Science Festival event hosted by School of Chemistry and Biochemistry Assistant Professor Andrew McShan, develops an innovative outreach and teaching module around nuclear magnetic resonance (NMR) techniques, and is designed for easy adoption in introductory chemistry and biochemistry courses. 

Published earlier this year in the Journal of Chemical Education, the study, “Automated Chemical Profiling of Wine by Solution NMR Spectroscopy: A Demonstration for Outreach and Education” was led by a team from the School of Chemistry and Biochemistry including lead author McShan, Ph.D. students Lily Capeci, Elizabeth A. Corbin, Ruoqing Jia, Miriam K. Simma, and F. N. U. Vidya, Academic Professional Mary E. Peek, and Georgia Tech NMR Center Co-Directors Johannes E. Leisen and Hongwei Wu.

“NMR is one of the most widely used analytical tools in chemistry and the life sciences, and Georgia Tech hosts one of the most cutting-edge NMR centers in the world,” McShan says. “Our study shows that you don’t need advanced training to appreciate how powerful tools like NMR work and how those tools are used in research.”

All materials, tutorials, and data are freely available via online tutorials and a YouTube video, enabling educators to replicate or adapt the activity even in settings with limited access to NMR facilities.

Wine sleuthing at the Atlanta Science Festival

From families with K-12 students to undergraduates to adults with no prior chemistry experience, nearly 130 visitors explored wine chemistry at the Georgia Tech NMR Center during the Atlanta Science Festival event. With McShan’s guidance, they identified and quantified more than 70 chemical components that influence wine taste, aroma, and quality by analyzing the chemical composition, structure, and dynamics of molecules.

Taking on the role of wine investigators (a real-world application of NMR), the group investigated examples of wine fraud, learning to identify harmful additives like methanol, antifreeze, and lead acetate – additives that played roles in both historical and modern wine scandals.

“By connecting the science to something familiar like wine, we were able to spark curiosity and excitement across age groups,” says McShan. “This a framework for how complex analytical techniques can be made inclusive, interactive, and inspiring whether in the classroom or at a science festival.”

Science for all

The study underscores the potential of NMR and other powerful technologies as outreach opportunities – from engaging the public to better teaching undergraduate students.

“After the event, adults said they learned how chemical composition affects wine characteristics and how NMR is used in research and industry,” McShan says. “Younger participants learned key concepts about wine composition and found benefits from the sensory elements, like watching the spectrometer in action.”

They aim to use these takeaways to continue developing outreach tools. “My end goal is to develop NMR into a practical teaching tool by grounding the technique in real-world examples,” adds McShan. “Using this approach is a clear avenue to introducing the general public to the world-class instruments used by researchers at Georgia Tech and exposing undergraduate students to the powerful analytical techniques they are likely to encounter throughout their careers.”
