Andrei Fedorov and his team have found a way to take some of the guesswork out of mass spectrometry imaging (MSI), potentially giving scientists better tools to explore the molecules that influence our health. 

A small sample of human tissue can hold a remarkable amount of information. 

Alexandra Rodríguez Dalmau, a community-engaged sustainability project manager with SCoRE, focuses on ensuring that communities have a meaningful role in shaping emerging energy transition technologies (EETTs) from the earliest stages of research through design and deployment. Her work sits at the intersection of research and practice, connecting technical expertise with community priorities related to energy, climate, and sustainability.

"Our main objective is to create a platform and process based on trust, where communities and technical experts can learn from one another," Rodríguez Dalmau said. "The goal is not to convince communities to support a particular technology, but rather to help everyone better understand the opportunities, tradeoffs, impacts, and questions that come with these technologies."

One of these projects is a regional community engagement program connected to the Southeast Direct Air Capture Hub (SEDAC), a U.S. Department of Energy-funded initiative led by the Southern States Energy Board. As conversations unfolded around direct air capture, a technology that removes carbon dioxide directly from the atmosphere, it became clear that many of the same questions and concerns can apply to the broader set of EETTs. Scaling low-carbon energy sources and systems that manage carbon after energy is produced — like hydrogen production, renewable energy systems, battery technologies, and energy infrastructure upgrades — may be considered an unqualified good thing. The SEDAC program brought to light that communities where such projects are built have a different perspective.

In the Fall of 2025, that SEDAC platform grew into the Southeast Community Energy Futures Academy (SCEFA), a training program and community of practice that brings together communities, technology researchers, and project developers to explore both the promises and challenges of EETTs.

"Communities are often asked to host facilities or infrastructure projects that serve broader resilience or climate goals," Rodríguez Dalmau said. "The benefits can feel distant while the risks and disruptions are immediate and local. Engaging communities early in the process is critical to ensuring that EETTs align with local priorities and support communities' own visions for a sustainable future."

Rather than positioning researchers as the sole experts, the program facilitates collaborative learning and centers the knowledge of community partners as experts who possess deep understanding of local history, priorities, and concerns. Participants engage in presentations, working sessions, mapping exercises, and laboratory tours. But one of the most significant elements of the program takes place outside of these sessions.

Community site visits bring participants directly into industrial and research facilities as well as neighborhoods affected by existing industrial development. Participants see schools, residential areas, power plants, natural amenities, research facilities, and community gathering spaces and hear from site managers and community leaders.

"Engaging with communities through experiential learning activities like site visits begins the process of rooting abstract technology into a place with all its history and memories of previous encounters with industrial plants. This enables conversations instead of silence or skepticism,” says Matthew Realff, professor and David I.J. Wang Faculty Fellow in the School of Chemical and Biomolecular Engineering, and faculty director for Interdisciplinary Sustainability Education at the Brook Byers Institute for Sustainable Systems.

The SCEFA effort is a culmination of SCoRE’s relationship and project-building work over the past 11 years. Community partners who participated in the SEDAC Hub and SCEFA discussions have become key contributors to a broader regional effort that now encompasses teams from Georgia, Alabama, Mississippi, and Louisiana. The initiative brings together leaders of nonprofits and community-based organizations, researchers, student interns, and project developers to learn from each other and develop education and outreach materials related to EETTs.

Over the course of one year, participants engaged in multiple online workshops, two in-person workshops — in Baton Rouge, Louisiana, hosted by Louisiana State University, and in Mobile, Alabama, hosted by the University of South Alabama — and developed education and outreach materials to be used by community-based organizations.

The program also encourages the formation of what SCoRE describes as "unlikely coalitions" among community organizations, universities, and industry professionals. The Georgia team, spearheaded by a researcher at Georgia College and State University, is exploring how nature-based sequestration and biomass energy may be used to enhance the land and other natural amenities that residents in their rural communities see as their legacy. The Alabama team focused on carbon capture, utilization, and storage (CCUS), which is the key EETT focus in their geography. The lead organization for that team, Iyai+ (Introducing Youth to American Infrastructure), developed a role-playing game that helps participants explore the opportunities and challenges associated with CCUS, identify key stakeholders, and practice asking critical questions about proposed projects.

Jennifer Hirsch, senior director of SCoRE, who is a cultural anthropologist and serves as project lead, explained, “SCEFA prioritizes building relationships over time, with a core focus on experiencing and learning together, rather than trying to get one side to see the other’s point of view. It is only when community perspectives are taken into account that truly innovative solutions will emerge that benefit both people and climate.”

The emphasis is on process rather than predetermined outcomes. Participants spend time learning how to ask better questions, evaluate evidence, and recognize uncertainties. By investing in a shared process, participants are often better able to navigate disagreement without becoming defensive.

The approach is already producing results. Technologists involved in the program have expressed greater interest in engaging with communities earlier in their research and development process. Researchers are exploring new ways to communicate findings more clearly and transparently. Community partners are gaining knowledge, tools, and resources that allow them to engage on their own terms when new projects are proposed.

“Lasting solutions emerge when researchers and communities work together from the beginning, asking the right questions and considering both the opportunities and tradeoffs,” said Tim Lieuwen, executive vice president for Research. “SCEFA offers a powerful model for developing energy solutions with communities, not simply for them. This collaborative approach reflects how Georgia Tech can help address complex challenges that no institution or community can solve alone.”

Hosted by Georgia Tech's Strategic Energy Institute (SEI), the annual summit brought together representatives from academia, industry, government, national laboratories, and nonprofits to discuss strengthening energy systems and preparing for a changing energy future. Topics focused on collaboration, workforce development, and strategies for building resilience amid the challenges in the energy sector.

"Energy resilience requires more than technological innovation. It depends on strong partnerships across universities, industry, government, and national laboratories," said SEI Executive Director Yuanzhi Tang, who delivered the summit’s opening remarks. "The UEILC Summit serves as an important forum to exchange ideas, identify shared challenges, and build collaborations among energy institutes across the country. These efforts are essential to strengthening energy systems and preparing the workforce that will support them."

Following Tang, Tim Lieuwen, Georgia Tech's interim president and executive vice president for Research, delivered a keynote address on academia's role in advancing a resilient energy future. Lieuwen emphasized the unique role of universities as trusted conveners and honest brokers, bringing together stakeholders with diverse perspectives to navigate an evolving energy ecosystem. 

A fireside chat featuring Mike Caravaggio of EPRI, Stephanie Gossman of Georgia Power, and Tang explored how artificial intelligence, data center expansion, and rising electricity demand are reshaping the energy landscape. The speakers also discussed how their organizations are working to strengthen grid reliability, expand infrastructure, and support a reliable energy future.

Founded with support from the Alfred P. Sloan Foundation to strengthen collaboration among university energy institutes, the University Energy Institute Leadership Collaborative provides a forum for advancing energy research, education, and engagement.

“A systems approach to today’s energy challenges — where academia, industry, and government collaborate to provide many perspectives on a problem — can only happen if there is a venue and a community where these discussions can safely take place,” says Daniel Tkacik, executive director of Carnegie Mellon’s Scott Institute for Energy Innovation as well as the principal investigator of the Sloan Foundation grant that supports the UEILC. “This summit continues to provide that valuable venue for collaboration, and we are grateful to our generous hosts at Georgia Tech.”

The summit theme, Expanding Collaborations for Resilient Energy Futures, framed discussions on regional energy resilience, grid vulnerabilities, geopolitical influences on energy planning, the growth of data centers, and workforce education. 

"The UEILC annual summit provides an excellent opportunity for energy institute leaders from across the nation to come together and share perspectives, strengthen partnerships, and advance solutions that can help shape more resilient energy futures," said Christine Conwell, director of planning and operations at SEI. "The conversations over the course of the summit reinforced the importance of cross-sector partnerships in creating new opportunities for innovation."

Conversations and networking opportunities provided a broader understanding of how different regions are strengthening energy resilience, addressing emerging threats to power infrastructure, adapting to geopolitical and economic shifts, and preparing for increased electricity demand driven by artificial intelligence and data centers.

"It was exciting to see so many diverse perspectives united by a common goal of building more resilient energy systems," said Jordann Britt, SEI program manager and a UEILC Bridge-Builder Fellow. 

Britt helped organize the summit as part of the UEILC Bridge-Builder Fellows Program, which supports emerging leaders in the university energy community.

Presented by Georgia Tech’s Office of Technology Licensing (OTL), the awards recognize researchers and inventors whose work demonstrates a strong commitment to moving Georgia Tech discoveries beyond the laboratory and toward real-world applications.

Xu was selected from among Georgia Tech inventors in recognition of her commitment to commercialization and her efforts to translate research into technologies that can address practical challenges.

Her research spans analytical chemistry, sensor development, nanotechnology, and water treatment, with applications that include food safety, medical diagnostics, environmental monitoring, and pathogen detection. Her work has included developing optical sensing technologies for rapid chemical and biological detection, supported through collaborations with government agencies, industry, and other research organizations.

That emphasis on moving research into the field reflects the purpose of the Innovator Awards and OTL’s broader mission of helping Georgia Tech intellectual property reach the marketplace through licensing, startup companies, and industry partnerships.

Xu earned her doctorate in analytical chemistry from Georgia Tech and has built a research career around technologies intended to solve real-world problems. She previously was recognized as a Regents’ Researcher by the University System of Georgia Board of Regents, its highest honor.

The Innovator of the Year recognition highlights not only Xu’s technical research, but also the process required to move promising discoveries toward practical use. Commercialization can connect researchers with industry partners, entrepreneurs, and other organizations that can develop laboratory innovations into products and technologies with broader societal impact.

Through the inaugural Innovator Awards Celebration, OTL is highlighting Georgia Tech researchers who have embraced that process and helped extend the impact of Institute research beyond campus.

Xu’s selection as Innovator of the Year recognizes her contributions to that effort and GTRI’s continuing role in developing applied research that moves from innovative ideas to solutions with meaningful real-world impact.

Q&A With Jie Xu

Q:  What does being named Georgia Tech’s Innovator of the Year mean to you, particularly given that the recognition emphasizes moving research toward commercialization and real-world use?
Receiving this recognition is deeply humbling, especially knowing how much groundbreaking work happens across Georgia Tech every day. What makes this award particularly special to me is its emphasis on translation and commercialization.
Research achieves its fullest potential when it leaves the lab and improves lives, industries, or the environment. Translating early-stage science into commercialized, real-world solutions is rarely a linear path—it takes resilience, multidisciplinary teamwork, and an entrepreneurial mindset. This honor belongs just as much to my collaborators, lab team, and partners who share the commitment to moving technology from concept to application. To have Georgia Tech recognize our work through the lens of real-world impact is both a rewarding milestone and a powerful motivation to keep pushing our innovations further out into the world.

Q:  What is one example from your research where the path from an interesting scientific result to something potentially useful in the real world was especially clear to you?
With our wastewater adsorbent research, getting high target-specific capture in a beaker was a great first step, but the path to a real-world tool wasn't clear until we figured out capture and recovery. Fine adsorbents disperse quickly, but pulling them back out of thousands of gallons of water is where applied nanotech usually breaks down. Once we demonstrated a rapid, economical way to capture and reuse the spent media, that lab result became a truly scalable, field-ready solution.

Q:  What is the hardest part of translating research into something that can actually be commercialized or adopted by users, and what have you learned about overcoming that gap?
Translating research into a commercial product requires accepting that benchtop success is just the starting point; the real test is building resilience through real-world deployment. With sensor development, achieving high sensitivity in clean, controlled samples is relatively easy. The fundamental commercialization barrier is data consistency when exposing sensors to raw field matrices with shifting background chemistry, biofouling, and suspended solids. We learned that you rarely anticipate every environmental challenge from day one; robustness evolves over time through field testing and continuous iteration.

Q:  How has working at GTRI, with its emphasis on applied research and sponsor needs, influenced the way you think about innovation and commercialization?
GTRI’s applied research culture thrives on close industry partnerships. Working directly with partners gives us an unfiltered view of the real problem space and operational needs. It ensures commercialization isn't an afterthought, but an evolutionary design process driven by partner feedback, turning high-performance lab concepts into scalable, field-deployable technologies that solve genuine industrial challenges.

Q:  For researchers who may have promising technology but have never pursued licensing or commercialization, what would you encourage them to do differently, or earlier, in the research process?
My biggest advice is to step out of the lab and talk to end-users and industry partners as early as possible to confirm that the problem you are solving actually exists and that the technology is genuinely needed.

Q:  Complete this sentence: “I knew I was a researcher when …”
I knew I was a researcher when I felt that incredible excitement of cracking a tough problem at the lab bench. Experiencing the rush of a major breakthrough and realizing how much I loved the hands-on problem-solving process is what made me realize research was my calling. 
 

Lewis, a principal research scientist in GTRI’s Cybersecurity, Information Protection, and Hardware Evaluation Research Laboratory (CIPHER), has had a wide-ranging career spanning law enforcement, information technology, and advanced cybersecurity research.

Lewis was sworn in at the Georgia State Capitol on Thursday, Oct. 8. At the ceremony, held in Gov. Brian Kemp's office, Lewis was joined by a large contingent of family members.

Lewis was sworn in by Kemp. With his hand raised, he "solemnly" swore to "discharge and perform all the duties required of a member of the board of directors of the Georgia Emergency Communications Authority, according to the best of my ability and understanding."

The appointment comes as emergency communications systems increasingly depend on interconnected digital networks, making cybersecurity an integral part of public safety. Georgia law now requires the governor to appoint a cybersecurity subject-matter expert to serve on GECA’s board. House Bill 423, which passed in May 2025, established this requirement and expanded GECA’s responsibilities for developing and implementing Next Generation 911, or NG911, across Georgia.

NG911 represents a significant technological evolution from traditional 911 systems. Georgia law defines it as an Internet Protocol-based system designed to be secure, resilient, redundant, and interoperable. In addition to voice calls, NG911 infrastructure supports other forms of emergency communications and associated data.

That increased capability also creates a larger and more complex digital environment that must be protected from an increasingly broad cybersecurity threat landscape.

The 2025 legislation also directs GECA to establish and operate a network management center in coordination with cybersecurity subject-matter experts to protect the ESInet, core services, and public safety answering points. The authority is also responsible for monitoring network performance and coordinating technical standards intended to create an interconnected and interoperable statewide system.

Lewis brings experience to that mission from both sides of the cybersecurity “battlefield.”

His research at GTRI encompasses offensive and defensive cybersecurity topics, including penetration testing, red teaming, cyber threat emulation, defensive cyberspace operations, and threat hunting, among many others. His work frequently involves approaching systems from an adversary’s perspective to identify weaknesses before a malicious actor can exploit them.

“At GTRI, our team frequently collaborates with government and commercial organizations to simulate cyber-attacker techniques, identify system vulnerabilities, and design strategies to bolster defenses against real threats,” Lewis said in an interview.

Lewis has applied those skills to critical infrastructure and national security challenges. His GTRI work has included cybersecurity research involving electric power systems and other operational technology environments. In one Georgia Tech research effort, Lewis and other GTRI red-team researchers tested the security of electric utility technology by attempting the types of malicious actions a real-world attacker might use. He has also researched ways to detect abnormal cyber activity within electric power systems.

More recently, Lewis has contributed to Georgia Tech research designed to help hospitals identify, track, and mitigate vulnerabilities in network-connected medical devices, another environment in which cybersecurity failures can have consequences extending well beyond information technology systems.

That background is particularly relevant as 911 systems become more interconnected and can carry increasingly diverse forms of digital information.

Lewis also brings prior law enforcement experience to the appointment, giving him a perspective that bridges cybersecurity technology and the operational realities of public safety. Before joining GTRI, Lewis served in law enforcement and later worked in network and security engineering before moving into advanced cybersecurity research.

For Lewis, effective cybersecurity requires understanding not only how systems are intended to work, but how an adversary might attempt to make them fail.

“To excel in cybersecurity, one must master the art of thinking like an adversary,” Lewis said. “Regardless of your chosen cybersecurity specialization, you must constantly challenge assumptions by asking, ‘How can X be broken?’ This mindset uncovers hidden flaws before malicious actors can exploit them.”

Lewis said his work has been particularly meaningful when it helps protect systems whose reliability has real-world consequences. This vital work ties into the tenets of GTRI’s mission to:

• Improve the human condition. 
• Enhance State of Georgia economic development.
• Serve national security.

“The greatest fulfillment comes from realizing my contributions to enhancing the security of power grids, critical infrastructure, and national defense systems against genuine cyber threats,” he said.

His new role with GECA extends that mission to another form of critical infrastructure: the communications systems Georgians rely on when they need help most.

Two morning panels explored research collaboration and workforce adaptation, while an afternoon student poster session and a concurrent Tech AI Career Fair connected the discussions with research and career opportunities.

For Tim Brown, Georgia Tech’s academic program director for AI, helping people find the right expertise is a practical starting point. When people ask how to become involved in AI research and partnerships, he said, Tech AI can help connect their interests with researchers and projects.

“We get these inquiries every day,” Brown said. He encouraged students to share their résumés and areas of interest, and to seek out faculty whose research methods and fields of study align with their goals.

Tech AI’s broader purpose is to help industry, government, and other organizations move from research ideas to AI systems they can put to use. Part of the university-wide Georgia Tech AI ecosystem, Tech AI draws on expertise across the Institute’s colleges and schools, interdisciplinary research institutes, AI institutes, advanced computing infrastructure, and the Georgia Tech Research Institute (GTRI).

The "How Tech AI Collaborates" panel, moderated by Brown, examined what it takes to make those partnerships work, particularly when research depends on sensitive information or creates intellectual property.

Belinda Vogel, research engagement manager for the Georgia Tech Manufacturing Institute and the Renewable Bioproducts Institute, described plans to open advanced manufacturing capabilities to remote users in academia and industry. Such access could extend the reach of research facilities, but it also raises questions about how companies can benefit from AI while keeping their data private.

Kevin Dalmeijer, a senior research associate in Georgia Tech’s H. Milton Stewart School of Industrial and Systems Engineering and managing director of the NSF AI Institute for Advances in Optimization, described safeguards used in projects involving sensitive or controlled data. Those measures can restrict where information is stored, how students access it, and which AI tools they can use.

Dalmeijer also discussed internships that divide a student’s time between Georgia Tech research and work embedded within a company. Establishing clear boundaries at the outset, he said, helps distinguish academic research from company-specific implementations and clarifies expectations for data and intellectual property.

Brown brought Ajay Upadhyaya, Tech AI’s associate director for research administration, from the audience into the discussion to explain another approach. Upadhyaya described developing foundational models with synthetic data, allowing students to publish academic work, then defining separate ownership for work incorporating a company’s proprietary data. He emphasized the importance of clearly specifying those boundaries.

The panel also looked toward emerging computing capabilities. Jeffrey Young, a Georgia Tech principal research scientist working with the Partnership for an Advanced Computing Environment, discussed how AI could help researchers improve quantum systems and determine how best to map applications onto quantum hardware. His remarks pointed to a relationship in which AI can support the development of other computing technologies, even as researchers continue exploring their potential.

The second panel, “Workforce Adaptation in the Age of AI,” shifted the focus to the people learning and working with these tools. Moderator Leigh Hopkins, assistant director of Georgia Tech’s Center for Economic Development Research, described a workforce being asked to adapt while the technology itself rapidly changes.

David Joyner, Georgia Tech’s interim vice provost for AI in Education and executive director of its Online Master of Science in Computer Science program, said AI familiarity is moving toward becoming an expected professional skill. He compared that transition with an earlier era when applicants listed typing speed on their résumés before such capabilities became “baseline.”

People still need the knowledge and judgment to do the underlying work themselves, Joyner said. Learning to use AI must be paired with learning to evaluate its output and avoid overreliance on the technology.

Georgia Tech faculty are exploring that balance through classroom experimentation, from changing assignments to developing tools tailored to particular courses. Joyner described the Academic AI Playbook as a way to share what individual instructors tried, the challenges they encountered, and what others might learn from their experiences. The 2026 edition includes 67 faculty-authored articles and 20 lessons drawn from classroom experience.

Joyner also raised a longer-term question for employers and educators: If AI takes on tasks traditionally assigned to entry-level employees, how will those employees gain the experience needed to advance? He suggested that evaluating work, framing problems, and defining clear requirements will become increasingly important as people take responsibility for directing AI-assisted work.

Georgia Tech alum Brian Greene, an operations and supply-chain executive, brought the discussion back to organizational decision-making. Companies can become so focused on acquiring an AI tool, he said, that they overlook the business need it is supposed to address.

“What’s the problem you’re trying to solve?” Greene asked. He urged organizations to begin with that question and work backward to the capabilities and partnerships they need. For smaller businesses with limited resources, choosing a tool without a clear purpose can be especially costly.

Narayanan (KK) Krishnakumar, chief technology officer at Delta Air Lines, offered examples of AI at work in a large organization. He described systems that help optimize baggage routing and generative AI tools that summarize information for customer-service employees. Across those applications, he emphasized the continuing need to verify AI-generated information.

For both Krishnakumar and Greene, the qualities employers value remain the same as they have traditionally been: curiosity, problem-solving, collaboration, and an ability to deliver results. AI fluency adds to those capabilities while making sound judgments about data and answers all the more necessary.

The afternoon poster session demonstrated how widely those questions now reach. Student projects explored trustworthy optimization, AI agents and responsible design alongside research on education, city planning and biomedical diagnostics. Other work addressed materials discovery and sustainable material selection, quantum chemistry, signal analysis, and AI that could support aging in place.

A well-attended career fair ran simultaneously with the symposium. In a large auditorium filled with company booths, students lined up to meet employers as both sides sought to connect research with potential positive industry outcomes.

“It’s a week-long event celebrating the different types of space research we’ve got going on at Georgia Tech, as well as the entrepreneurship,” Ready said. Ready added that the Institute's and Space Week's reach extends far beyond Georgia Tech. He noted that Space Week's roster of speakers included leading experts from industry and military research organizations such as Aerospace Corp. and the Air Force Research Laboratory (AFRL), as well as academic institutions such as Georgia State University, the State University of New York at Albany, the University of Michigan, San Diego State University, Florida State University, and the University of Maryland.

Ready said that Space Week highlighted the collaborative nature of SRI, as it continuously works with institutions and companies that support the three foundational pillars of SRI:

• Research and Development (R&D).
• Education.
• Commercialization/Entrepreneurship.

Space Week’s sponsors underscored SRI’s ability to bring together a broad network of collaborators extending well beyond Georgia Tech’s Atlanta home. Support came from Amazon; CreationsVC, Mantis Space and Varda Space Industries; Deleon.bio, Reed Smith and the Georgia Center of Innovation; and Nelson Mullins, Qcells and West Coast Solutions. The roster connected Georgia’s space community with companies across the country, including  Varda Space Industries and West Coast Solutions, which are based on the other coast in California.

The event highlighted the breadth of research across sensing, materials, computing, policy, and human exploration. Participants examined problems that demand expertise from multiple disciplines. SRI provides a home for those connections, bringing together faculty, staff, and students whose work contributes to space exploration and discovery. Space Week made it visible through research presentations, conversations about new collaborations, and student projects supported by the institute.

GTRI's Role

GTRI, the applied research arm of Georgia Tech, played a significant role during Space Week and in the Institute’s growing contributions to research on the technical challenges of reaching space and operating there.

Michael Peterson, director of GTRI’s Severe Storms Research Center (SSRC), organized the Terrestrial and Space Weather session and presented FulminoSat, a concept examining severe-weather lightning signals as a space-based sensing opportunity for studying ionospheric effects.

Elena Plis, a senior research engineer in the Electro-Optical System Laboratory (EOSL), led a program on the weathering of materials in space, where researchers considered how exposure changes the materials spacecraft depend on. GTRI’s Ryan Gaylo, a senior research engineer in the Aerospace, Transportation and Advanced Systems Laboratory (ATAS), presented SolarWing, a bio-inspired deployment system for solar arrays.

During a track dedicated to hypersonics, GTRI ATAS laboratory researcher and GT Regents' Professor Krish Ahuja spoke on the HyperSat project. Graduate Research Assistant Michael Milone presented on GTRI's experimental hypersonic test capabilities. At the same time, ATAS senior research engineer Alex Forbes discussed hypersonic computational fluid dynamics. Those topics highlighted complementary approaches to understanding flight under extreme conditions.

Ahuja, one of the foremost experts in hypersonics and a pioneer in the field, led the track alongside ATAS laboratory Principal Research Engineer Rob Funk.

Understanding what surrounds a spacecraft is another essential part of protecting it. That challenge anchored a session organized by Douglas Hope, who moved from GTRI to Georgia Tech’s School of Physics at the end of August.

Hope described space domain awareness as a progression: detect an object, track its orbit, identify it, and use that knowledge to predict its behavior. Distinguishing an operational satellite from debris requires more than knowing where a point of light appears in the sky.

“Essentially, where is it? What is it? What is it doing?” Hope said.

He described an SRI-supported initiative to establish a center for space domain awareness research, connecting expertise in physics, engineering, policy and machine learning. The effort seeks to bring researchers across schools together to pursue opportunities that draw on their combined strengths.

Hope’s own presentation examined the difficult problem of detecting faint objects near bright satellites. Optical sensing and image analysis could help reveal objects that would otherwise be obscured, providing a clearer understanding of a spacecraft’s surroundings. His move to Physics carries that research forward while strengthening connections between GTRI experience and Georgia Tech’s academic community.

Policy discussions explored how those technical capabilities fit within the rules and relationships governing space activity. Mariel Borowitz, an associate professor in the Sam Nunn School of International Affairs and an SRI associate director, emphasized the connections among engineering, policy, and international affairs. Topics included orbital sustainability, commercial activity, and the choices governments make about space programs.

“It’s really those interconnections that give Georgia Tech an edge,” Borowitz said.

Astronauts - Past and Future

Sandra Magnus, a former NASA astronaut and now a Georgia Tech professor of the practice, brought an operational perspective to the evolution of human spaceflight and the changing relationship between government and commercial providers. Her discussion linked decisions about future destinations with the institutions and partnerships needed to reach them.

Space Week also demonstrated that Georgia Tech’s role extends to preparing the people who will build, test, and maintain future aerospace systems. Ready and Stephen Ruffin, interim chair and a professor at the Daniel Guggenheim School of Aerospace Engineering at Georgia Tech and director of NASA’s Georgia Space Grant Consortium, discussed the Southeast Space Technology and Aerospace Readiness Skills initiative (SE-STARS).

Georgia Tech leads the Georgia hub in NASA’s inaugural cohort of seven Aerospace Skilled Technical Workforce Hubs, or NASA State Hubs. Announced in August, the national initiative has awarded approximately $10.5 million across the seven institutions. Georgia Tech’s SE-STARS award provides $1.5 million over three years.

NASA Associate Administrator for STEM Engagement Elaine Ho described the program’s origins and workforce priorities during her Space Week keynote. NASA had convened the inaugural hub leaders in Houston just the previous week, underscoring how early Georgia Tech is helping shape this new effort.

The hubs are designed to connect employers, education providers and workforce organizations around technical careers such as machining, electronics, welding and systems integration. These jobs require substantial expertise, with many offering pathways that do not require a bachelor’s degree.

Ruffin serves as principal investigator for SE-STARS, with Ready among its co-principal investigators. Partners include SRI, the Georgia Space Grant Consortium, the Georgia Tech Manufacturing Institute, the Technical College System of Georgia, Georgia Southern University, and aerospace employers. The Technical College System’s 22 colleges and 88 campuses give the partnership statewide reach.

The goal is to connect education with industry needs through relevant curricula, credentials, and practical experience. For Georgia Tech, leading an inaugural hub creates an opportunity to help develop a model for aerospace workforce preparation while extending access to careers across Georgia and beyond.

Students at Space Week showed what taking responsibility for a mission can look like well before a first industry job. Georgia Tech aerospace engineering undergraduates Bella Diedrich and Gabriel Buggi presented Southeast Analog, a student-led program that simulates space missions on Earth.

More than 100 students have contributed as mission designers, investigators, analog astronauts, and flight controllers, the presenters said. Early SRI funding helped the team purchase equipment and support selection and training activities, turning an ambitious concept into an operational program.

An August mission placed analog astronauts in Arkansas and flight controllers in Georgia, with a simulated 20-minute communications delay in each direction. That separation required participants to plan carefully, communicate clearly, and make decisions without the convenience of an immediate reply. Students gained experience with the technical and human demands of mission operations while developing a more accessible route into spaceflight-related work.

Their presentation exemplified a point Ready emphasized throughout the event: students were contributing to the research community while also learning from it.

“It’s been great to see the students get involved, both as attendees as well as presenters,” he said.Former NASA astronaut Jeanette Epps offered a real-world view of preparation, describing her training in T-38 jets, robotics, spacewalk procedures, and emergency response. Drawing on her experience during NASA’s SpaceX Crew-8 mission, which included 232 days aboard the International Space Station, she explained the teamwork and adaptability required to operate in demanding environments.

That connection between preparation and practice ran through the four-day Space Week program. Georgia Tech researchers presented work on microgravity systems, lunar resources, robotics and spacecraft design. A poster presentation gave students and researchers opportunities to discuss their projects with visitors from government, industry and academia. Entrepreneurship sessions examined how space companies are financed and built, while a public observatory night extended the event’s reach beyond the research community.

Space Week brought the Institute’s capabilities to the fore for attendees from throughout the nation. Georgia Tech’s academic expertise, GTRI’s applied research, and SRI’s support for collaboration form a common foundation for work already “in flight” and to be “launched."

Hosted at the Georgia Tech Kendeda Building for Innovative Sustainable Design, the workshop was organized by a committee of researchers and practitioners from across the macro-energy systems community. The committee was chaired by Micah Ziegler, assistant professor in the School of Chemical and Biomolecular Engineering and the Jimmy and Rosalynn Carter School of Public Policy. 

The two-day workshop brought together more than 130 participants and featured lightning talks, poster presentations, interactive learning sessions, and keynote addresses that strengthened connections across the macro-energy systems research community.

“The energy challenges facing society today are increasingly interconnected, and solving them requires a systems-level perspective,” said Christine Conwell, director of planning and operations at the Georgia Tech Strategic Energy Institute. “Supporting events like the MES Workshop, which provides a unique space for academic collaboration and knowledge sharing, aligns with the Strategic Energy Institute’s commitment to advancing research and workforce development that support more resilient and effective energy solutions.”

The workshop received financial support from the Alfred P. Sloan Foundation, which supports research and education in science, technology, engineering, math, and economics. Through its Energy and Environment program, the foundation helps advance interdisciplinary research and collaboration across the macro-energy systems field.

“The Macro-Energy Systems Workshop has become a significant forum for interdisciplinary energy systems researchers to share and discuss their work,” said Evan Michelson, director of the Alfred P. Sloan Foundation’s Energy and Environment program. “We were especially glad to help ensure participation from early-career researchers spanning a wide range of institutions, providing them access to the collaborations and conversations that will help them develop as scientists.”

Graduate students and postdoctoral scholars played a central role in this year's workshop, presenting research on energy system planning, grid reliability, technology deployment, energy transitions, and policy. Their sessions gave the early-career researchers opportunities to share new approaches to studying large-scale energy systems, interact with faculty and industry experts, refine research ideas, and build collaborations beyond their home institutions.

“This year, we significantly expanded the MES Workshop to include more early-career scholars,” said Ziegler. “The workshop provides a great opportunity for young researchers to develop ideas, connections, and a better understanding of how to design research to have a positive impact on the world.”

The workshop also featured keynote presentations from Kelly Sanders, professor of civil and environmental engineering at the University of Southern California, and Erin Mayfield, assistant professor at Dartmouth College's Thayer School of Engineering. Both speakers discussed insights from their experience contributing to policymaking and highlighted opportunities for energy systems research to inform policy decisions.

Interactive sessions led by Michelle Graff, assistant professor in the Georgia Tech Jimmy and Rosalynn Carter School of Public Policy encouraged participants to consider how macro-energy systems research can more effectively inform and support policymakers and other decision-makers. Graff developed and facilitated the sessions, with support from Morgan Edwards, assistant professor of public affairs from the University of Wisconsin-Madison, and Micah Ziegler. The first session explored how researchers can identify policy windows and position their work to inform decision-making at the right time. The second focused on matching research to the appropriate audiences and jurisdictions, highlighting opportunities to inform policy at the state and local levels.

Designed for industry professionals, policymakers, educators, students, community leaders, and members of the public, the lunchtime webinar series provided an accessible introduction to the key issues influencing the nuclear energy sector at a time of growing interest in nuclear power as part of the global energy transition.

The series began on Aug. 20 with The New Nuclear, presented by Steven Biegalski, chair of the Nuclear and Radiological Engineering and Medical Physics program. The session examined the evolution of nuclear reactor technology, from today's operating fleet and the AP1000 reactors at Plant Vogtle to emerging small modular reactors and advanced reactor designs.

The second webinar, held Sept. 3, focused on the economics and policy landscape of nuclear power. Laura Taylor, director of EPIcenter and professor of economics at Georgia Tech, joined Stephen Comello, executive vice president and executive director of the Nuclear Scaling Initiative at the EFI Foundation, to discuss the economic drivers, policy considerations, and opportunities influencing nuclear energy development in the United States.

The series concluded on Sept. 17 with a discussion of nuclear fuel, security, and geopolitics. Anna Erickson, Woodruff Professor of Nuclear Engineering, and Rachel Whitlark, associate professor in the Sam Nunn School of International Affairs, explored global nuclear energy growth, fuel supply chains, and the policies needed to support the safe, secure deployment of nuclear technologies worldwide.

Recordings and presentation materials from all three sessions are available on the webinar series webpage. Those who were unable to attend can watch the presentations and access the accompanying slides to learn more about the technologies, policies, and global trends shaping the future of nuclear energy.

Few neuroscientists would dispute that the brain relies on prediction. From houseflies evading swatters to humans catching baseballs, living things are constantly anticipating what comes next. Understanding how the brain generates those predictions could help explain one of neuroscience's most enduring questions: how the brain builds internal models of the world that allow us to learn, adapt, and anticipate what comes next.

“Without actively predicting the world, we cannot survive,” says Farzaneh Najafi, an assistant professor in the School of Biological Sciences and a faculty affiliate of Georgia Tech's Institute for Neuroscience, Neurotechnology, and Society. “There is quite some sensory-motor delay in the processing. We can’t just sit there, wait for the brain to process our environment, and then react.”

Part of the puzzle may lie in signals known as neural ramps. Almost like a drumroll leading up to a big reveal, neurons in some areas of the brain have shown gradual increases in activity immediately before a stimulus appears. For decades, researchers have interpreted this ramping activity as a neural signature of prediction, reflecting anticipation of an upcoming event.

Recently published in Science Advances, a new study from Najafi’s lab reveals these signals may not be “predictions” at all, but instead a way neurons track elapsed time.

“Surprisingly,” says Najafi, “the very first study from my lab called the Predictive Processing Lab showed that no, these are not prediction signals.”

The finding challenges a long-standing interpretation of one of neuroscience's most studied signals and reveals that the search for predictive neurons may lead to different circuits — or require different experiments to uncover. 

At the heart of the new lab is the miniTrashpresso, a compact recycling and manufacturing system developed by the sustainability technology company Miniwiz. The machine can take used plastics and other waste materials, process them locally, and transform them into new products in less than five minutes. By bringing manufacturing and recycling together in a single system, the Trash Lab aims to give the Georgia Tech community a way to explore sustainable design, material reuse, and the future of circular manufacturing.

“The launch of IPaT’s new Trash Lab represents an exciting step forward for sustainability at Georgia Tech,” said Jennifer Chirico, associate vice president of Sustainability. “As a living-learning lab, it provides students and researchers with hands-on opportunities to work alongside campus operations, turning used plastics into valuable new products and creating innovative solutions that support a more circular campus.”

A Makerspace Focused on Circular Innovation

The Trash Lab expands Georgia Tech’s growing network of makerspaces and innovation environments by focusing specifically on waste recovery and reuse. Instead of treating used plastics as disposable materials, the lab encourages users to view them as valuable resources that can be transformed into new products.

The miniTrashpresso represents the latest generation of recycling technology developed by Miniwiz. The company originally launched the world’s first mobile recycling line, known as the Trashpresso, to support communities that lacked access to traditional recycling infrastructure. The newer miniTrashpresso is smaller, more energy-efficient, and more portable, making it suitable for campuses and community-based applications.

The modular system uses industrial equipment, including shredders, presses, and heating technologies, to process materials on-site. Advanced heat-induction presses and specialized molds can quickly transform recovered plastics into new objects and components. The system can also be integrated with AI-powered waste-tracking tools and robotic automation technologies that help identify, sort, and process materials more efficiently.

For IPaT leaders, the Trash Lab represents more than the addition of specialized equipment.

“Community resilience and people-centered sustainability are core research areas within IPaT,” said Michael Best, executive director. “Our new Trash Lab will allow the entire Georgia Tech community to not only think about upcycling and plastic reuse but to make and do innovative projects that directly demonstrate sustainable futures.”

Turning Trash Into a Resource

Miniwiz founder Arthur Huang, who developed the miniTrashpresso system, describes upcycling as a practice rooted in centuries of human ingenuity.

“Upcycling is actually recycling old material and turning that into something new,” Huang said.

Throughout history, societies have reused existing materials in construction, manufacturing, and everyday life. According to Huang, modern waste streams, particularly plastic packaging and electronic waste, represent an enormous and often untapped source of raw materials.

The miniTrashpresso was designed around that idea. Rather than transporting waste long distances to centralized facilities, the system enables materials to be processed where they are collected. By reducing transportation needs and creating opportunities for local manufacturing, decentralized recycling systems can help lower the environmental footprint associated with traditional waste management.

Miniwiz estimates that using recycled materials can reduce embedded energy consumption by 60% to 80% compared with using raw materials. The company has developed more than 1,200 upcycled materials and products from everyday waste streams, including plastics, food packaging, coffee cups, and electronic waste.

Since its introduction, Miniwiz technology has been deployed in communities, campuses, and organizations worldwide, including projects in Taiwan, Italy, Singapore, Sweden, Saudi Arabia, Thailand, the United Kingdom, and the United Arab Emirates. According to Huang, Georgia Tech is installing and operating North America’s first miniTrashpresso recycling machine from Miniwiz.

Building a Community Around Sustainability

The new facility is also intended to serve as a gathering place for interdisciplinary collaboration. Students interested in sustainability, materials science, engineering, design, manufacturing, and public policy will have opportunities to experiment with new ideas while working with researchers and campus partners.

“When Michael Best first pitched the idea of the Trash Lab, I expected there to be interest in a space like this given the general momentum toward sustainable practices on campus, but the level of excitement from students, staff, and faculty has been outstanding,” said Tim Trent, IPaT’s lab director for the Trash, Craft, Prototyping, and Usability Labs.

“This is an opportunity to create a gathering point for sustainability initiatives, act as a catalyst for partnerships, and help strengthen the many amazing networks and projects already present on campus,” he said. “The IPaT Innovation Labs have a continuous focus on supporting the overall Georgia Tech research enterprise, and I’m happy we are adding another piece to the portfolio.”

As the Trash Lab opens its doors, members of the Georgia Tech community will be invited to explore how waste materials can be reimagined as resources, prototypes, and products. By combining makerspace culture, advanced recycling technology, and sustainability research, the lab offers a tangible demonstration of how circular economy principles can move from theory into practice.

For Georgia Tech, the Trash Lab is not simply a place to recycle plastic. It is a space where innovation, design, and sustainability intersect, helping transform discarded materials into opportunities for learning, discovery, and impact.

For decades, immunologists have known that the body's most durable defenses depend on plasma cells, the antibody-producing cells responsible for long-term immune memory. Long after an infection has passed or a vaccine has been administered, these cells continue releasing protective antibodies, sometimes for decades. 

The CHORUS (Community Hubs for Optimizing Resilience) project will collaborate with coastal communities in Georgia and New York and will be split into two pieces: technology development and community engagement. 

“We’re not just building a simulator and hoping it fits the needs of coastal residents,” explains Alex Robel, project leader and Jean “Chris” Purvis Associate Professor in the School of Earth and Atmospheric Sciences. "By collaborating with community partners from the very beginning, we can ensure that what we ultimately develop will be effective because the people who will be using it are helping design it.”

Putting Flood Modeling in Residents' Hands

The technology development component will include faculty from the College of Sciences and the College of Computing. The College of Sciences team will develop an AI-based flood simulator and the College of Computing team led by Josiah Hester, associate professor and Catherine M. and James E. Allchin Early Career Professor, will create a web platform that allows users to visualize potential flood impacts.

Traditional flood models can take hours or days to generate results and often require specialized expertise and expensive computing resources. The CHORUS platform will be designed to provide easy-to-understand results in seconds, producing building-scale flood maps that show how water moves through streets, yards, and structures during a range of flooding scenarios. Researchers will use the model to test how specific interventions, such as seawalls, restored marshes, or improved stormwater infrastructure, could affect flooding.

Eventually, users will be able to test their own scenarios through the browser-based tool, enabling them to explore how different decisions could change flood impacts in their communities:

“Users will be able to go into a web browser and indicate where a sea wall could go or change a parking lot into a porous vegetated landscape, then click simulate. Within a few seconds, they’ll have a new flood map showing the impacts of these interventions,” says Robel.

A Community-Driven Approach

A collaborative effort with the New York Climate Exchange, the project will be funded by Georgia Sea Grant and IBM, with support from Georgia Tech for Georgia’s Tomorrow (GT2), Georgia Tech’s Coastal Equity and Resilience (CEAR) Hub, and the National Sea Grant College Program. The CHORUS project is an initiative of the New York Climate Exchange, where Georgia Tech is a core partner institution.

Community engagement in Georgia is being led by CEAR and the Pin Point Betterment Association, which represents descendants of the historic Gullah Geechee community near Savannah. In New York, the project team is partnering with the New York Climate Exchange and the Waterfront Alliance to work with communities surrounding Jamaica Bay.

“What makes this partnership meaningful is that it puts community voices at the center,” says Jasmine Smith, president of the Pin Point Betterment Association. “Too often, decisions are made to ‘better’ communities without actually involving the people who live there. We hope this partnership can serve as a blueprint for how communities are included in future sustainability projects from the very beginning.”

The project includes community advisory boards and technical advisory boards in both locations. Community members will help identify priority assets, select flood scenarios for analysis, and shape the design of the web-based tool. They’ll also test and offer feedback. Technical advisory boards made up of local officials, planners, and other experts will help evaluate the feasibility of proposed solutions.

“The aim is to blend information from both groups without allowing the technical perspective to override community priorities,” says Robel.

According to Robel, giving communities direct access to flood modeling tools can help close the gap between public input and infrastructure planning.

“We are putting decision making in the hands of the community. With a tool like this, the community can say: ‘We want to prevent flooding at this community center, this school, or this road,’” says Robel. “They can run the model, produce data, and present it to local governments or the Army Corps of Engineers  — advocating for potential solutions themselves rather than relying on outside experts.”

Robel sees this project as just the beginning:

“Funded by two-year grants, CHORUS is meant to be a pilot for how this kind of community-centered project can be done. Once we understand some of the challenges and opportunities involved, it will hopefully make it easier for us to scale this work to additional community partners.”

About Community-Engaged Research at Georgia Tech

Georgia Tech is actively working to foster more projects that foster community engagement. Collaborative groups at Georgia Tech involved in the CHORUS project include:

• The CEAR Hub, part of the Institute for People and Technology (IPaT), and housed at the Georgia Tech Savannah campus, advances community-engaged research and planning throughout coastal Georgia, helping communities build resilience to environmental and climate challenges. 
• The Center for Sustainable Communities Research and Education (SCoRE) trains faculty, students, and staff in best practices for conducting community-engaged research as well as facilitating connections directly with communities.
• The Brook Byers Institute for Sustainable Systems (BBISS) houses SCoRE and is Georgia Tech’s point of contact to the New York Climate Exchange. BBISS forms partnerships like these to fulfill its mission to expand the reach and impact of Georgia Tech’s sustainability research. 

The agreement was signed during a Sept. 14 visit by PNNL leadership to Georgia Tech’s Advanced Manufacturing Pilot Facility. It builds on years of successful collaboration between researchers at the two institutions. 

The enhanced collaboration has three primary goals: solving big problems through multidisciplinary, multi-institutional research; sustaining and engaging human capital by creating opportunities for students, faculty, researchers, and interns to work on complex real-world challenges; and accelerating technology adoption by taking scientific discoveries and innovations into industry and the federal marketplace.

"Strengthening our partnerships with national laboratories is a strategic priority for Georgia Tech,” said Tim Lieuwen, executive vice president for Research at Georgia Tech. "PNNL is an outstanding partner, and we look forward to deepening connections among our researchers and students, expanding opportunities and access to world-class capabilities and facilities, and advancing discovery, innovation, and national impact together."

PNNL is a U.S. Department of Energy national laboratory that advances scientific discovery and innovations that support reliable energy, national security, and economic competitiveness. Georgia Tech is one of the nation's leading research universities, conducting more than $1.5 billion in research annually and pursuing a mission to develop leaders who advance technology and improve the human condition.

"PNNL and Georgia Tech have a long history of working together," said Deb Gracio, laboratory director of Pacific Northwest National Laboratory. “This agreement provides the foundation to take on difficult research challenges and to leverage our complementary expertise and investments in the years ahead.”

The Strategic Energy Institute (SEI) has played a central role in advancing Georgia Tech's engagement with the national laboratory system and connecting researchers with partnership opportunities.

"As SEI takes on a greater role in coordinating Georgia Tech's national laboratory partnerships, this agreement with PNNL demonstrates how we are building stronger pathways for faculty, researchers, and students to engage with world-class national lab capabilities," said Yuanzhi Tang, SEI executive director.

The National Laboratory Partnership Program supports engagement between Georgia Tech and the U.S. national laboratories. SEI now leads the program, with ongoing support from Georgia Tech’s Office of the Vice President for Interdisciplinary Research. The agreement with PNNL is the first formal agreement established through the program since its transition to SEI.

"This MOU formalizes and strengthens relationships that have been growing for many years," said Scott McWhorter, SEI director of national laboratory partnerships. “It leverages the unique strengths of Georgia Tech and PNNL and provides a framework for expanding engagement across areas of mutual interest.”

Georgia Tech and PNNL bring complementary strengths in energy and environmental systems, electric grid resilience, cybersecurity of critical infrastructure, alternative fuels and advanced materials, biofuels, radiation detection, data science and visual analytics, nuclear nonproliferation, and national security. These capabilities will be brough together through two upcoming Genesis Mission projects.

Bill Pike, PNNL's deputy director for Science and Technology, who joined the laboratory’s leadership delegation for the MOU signing, said the projects reflect the growing partnership and expanding collaboration between the two institutions.

Before a promising new therapy can reach a patient, researchers need to answer a deceptively simple question: Will it work? 

Opening the event, Ameet Pinto, BBISS faculty director for Interdisciplinary Research and Collaboration, noted that many critical infrastructure systems are facing unprecedented challenges. Aging assets, climate-related impacts, severe weather events, and growing demands on energy and water systems are testing the resilience of infrastructure that communities depend on. At the same time, infrastructure systems increasingly generate vast amounts of operational data through sensors, meters, and monitoring technologies. The opportunities for AI technologies to transform this data into actionable information and inform policy are just beginning to be explored.

Turning Infrastructure Data into Action

Molzahn's presentation focused on the electric grid and the ways AI-enhanced optimization can support smarter infrastructure management. He described the ongoing transition from large, centralized power plants to more distributed systems that incorporate renewable energy, battery storage, electric vehicles, and other distributed energy resources. While these technologies create opportunities for cleaner and more resilient energy systems, they also introduce new layers of complexity for planners and operators.

Among the examples Molzahn shared was research examining how electric vehicle charging could affect emergency evacuations during disasters such as wildfires. Traditional evacuation planning focuses on optimizing transportation networks for rapidly moving vehicles away from danger. However, with more EVs on the roads, consideration must be given to ensure that EVs will have sufficient charge to travel a safe distance when an evacuation order is given without overloading the electrical grid. By linking transportation and power-system models, researchers are demonstrating how planning strategies can significantly reduce stress on infrastructure while supporting faster evacuations.

Wildfire mitigation was another major focus. In recent years, several devastating wildfires have been linked to electricity infrastructure, prompting utilities to increasingly rely on Public Safety Power Shutoffs during high-risk conditions. Molzahn discussed how machine learning and optimization tools can help utilities make these difficult decisions more quickly by balancing ignition risk and minimizing customer outages.

He also highlighted emerging cybersecurity concerns associated with the trend towards more distributed energy resources. Decentralized and digitally connected energy infrastructure, such as internet-connected solar and battery systems, can be more vulnerable than legacy centralized energy sources. AI is playing an important role in identifying potential vulnerabilities.

Practical Applications in the Water Sector

Loe offered examples of how AI is already being deployed by water utilities and municipalities. One pressing challenge involves identifying lead service lines. New federal regulations require utilities to locate and replace lead service lines, but many organizations lack complete records identifying pipe materials. Loe described how utilities can combine statistical sampling and machine learning models to estimate which service lines are most likely to contain lead. Rather than excavating thousands of suspect locations, utilities can use AI to narrow the search, reducing costs while still meeting regulatory requirements and maintaining confidence in the results.

Loe also explained the overarching challenges of maintaining aging water infrastructure. Utilities across the country have significant backlogs of aging pipes that need replacement but lack the resources to replace every asset at once. Machine learning models can predict which pipes are most likely to fail, while optimization tools can prioritize and package disparate replacement jobs into efficient and practical construction projects for which funding can more easily be obtained. This approach allows organizations to move beyond simple age-based replacement strategies and incorporate factors such as risk, community priorities, paving schedules, traffic impacts, and equity considerations.

The Human Element

Although the discussion centered on AI, both speakers repeatedly emphasized that people remain critical to successful implementation. Panelists and audience members also discussed the importance of keeping "humans in the loop" since utility systems directly affect public safety. AI may generate recommendations, identify risks, or highlight priorities, but engineers, operators, and planners should remain responsible for evaluating those recommendations and making final decisions.

Workforce development emerged as another important theme. Both the water and energy sectors face challenges replacing experienced workers as many long-time professionals approach retirement. AI offers opportunities to preserve and transfer institutional knowledge that could enable smaller workforces, but both speakers stressed that future professionals will need expertise that spans engineering, data science, computing, and domain knowledge.

Looking Ahead

The discussion demonstrated that infrastructure resilience is increasingly both a physical and digital challenge. From wildfire management and grid reliability to lead service line replacements and predictive maintenance, AI and digital twins are enabling new opportunities to improve how critical systems are planned, operated, and maintained. However, better algorithms alone will not be enough to counter our aging infrastructure, climate impacts, cybersecurity risks, and rising resource demands. The thoughtful integration of advanced tools and human expertise and judgment built on a foundation of public trust offers the most effective solutions for keeping essential systems running.

Next in the Insights Series 

On October 14, BBISS will hold the next Insights Series at the John Lewis Student Center in the Rafael Bras Meeting Room. The topic will be “AI for Climate Resilience.” This session will explore how artificial intelligence is being leveraged to address pressing sustainability challenges and strengthen communities, infrastructure, and environmental systems in a changing climate. The program will open with an update from Jennifer Chirico on the Georgia Tech Climate Action Plan. Presentations from leading researchers will follow, including Suhas Jain, Ali Sarhadi, Abigale Stangl, and Iris Tien, followed by an interactive panel discussion. Breakfast will be served. Registration is required.

Ahmadi and Brown find that neighborhoods with higher shares of Black residents experience higher energy burdens, even after accounting for factors such as income, renter status, and housing characteristics. In this study, energy burden refers mainly to the share of household income spent on electricity, gas, and water. The authors estimate that an approximately 11 percentage-point increase in a neighborhood’s Black population share is associated with about a 1 percentage-point increase in household energy burden, equal to an average annual increase of about $785 in utility costs. These findings suggest that unequal energy burdens are tied not only to household finances, but also to the lasting effects of segregation and discrimination.

When Chevron reported its highest quarterly profit in six years on July 31, 2026, it was just one detail in a larger picture: Analyst firm Wood Mackenzie estimates the global oil and gas industry is on course for a cash windfall of US$495 billion in 2026. That’s profit above and beyond what the industry expected before the U.S.-Israel war with Iran began.

Three separate bills seeking to tax those profits are now in Congress, and President Donald Trump has even said the oil companies are “making too much money.”

As an applied microeconomist, I am often asked how taxes affect economic activity. Economists have long held a more nuanced view of windfall taxes than either side of the current debate suggests. Advocates often make overly optimistic revenue projections, and opponents often overstate how much such a tax might discourage investment. A 1980s U.S. windfall-tax experiment is instructive on both counts.

Read Full Story on The Conversation

The Georgia Tech Manufacturing Institute (GTMI), the Strategic Energy Institute (SEI), and the Supply Chain and Logistics Institute are racing to close the gap between what America invents and what it can build at scale. 

How does Atlanta's local food ecosystem function today? How do the people working inside it envision its future? And where are the opportunities for transformation?

Those three questions drive the systems and network mapping research of Nicole Kennard, a research scientist and assistant director for Community-Engaged Research at Georgia Tech’s Brook Byers Institute for Sustainable Systems (BBISS). Within a systems map, Kennard charts intersecting food challenges and the intervention strategies that could address them. A companion social network map reveals the relationships that already exist across the food ecosystem and who needs to be brought together to create change. Both feed into the Atlanta Food System Research Network, an effort to increase coordination and build teams around the food system's most stubborn, systemic challenges.

The mapping regularly shows one significant gap: One in eight metro Atlantans are struggling to access food. Although more local farmers are growing good food, there is a “missing middle layer” of infrastructure connecting that food to those who need it, according to Atlanta’s 2026 Climate Resilience Action Plan. Food produced by smaller farms often can’t enter traditional supply chains due to small quantities, so new models are needed to move that food in ways that people can access it within their everyday routines. A summer research trip through France, Belgium, and the U.K. provided her with fresh models for closing that gap.

"I learned a lot from these models that I'm trying to bring back to Atlanta for my systems mapping research," Kennard said. "One of the biggest issues is we're missing that middle layer — better ways to distribute local food so it's reaching all neighborhoods equitably, and it's actually accessible."

It's not Kennard's first time working on food systems abroad. After graduating from Georgia Tech with a degree in materials science and engineering and running a student-led hydroponics project that grew food for the Atlanta Community Food Bank, she spent nearly four years in the U.K. as a Fulbright Scholar, earning a master's in sustainable agriculture and food security at Newcastle University before completing a Ph.D. in chemistry and biosciences at the University of Sheffield in 2023. That background, she said, is part of what draws her to the field. "Food is the great connector."

Bringing Ideas Home From Europe

This summer, Kennard split her time between France, Belgium, and a return visit to Sheffield. At Georgia Tech-Europe, the institute's Metz campus, she met with Paul Voss, director of academic programs, to explore future partnerships around sustainable entrepreneurship and research, potentially bringing BBISS-affiliated faculty and coursework to the campus.

In Montpellier, she presented her work to three organizations clustered on a single campus: INRAE (France's National Research Institute for Agriculture, Food, and Environment), L'Institut Agro Montpellier, and CIRAD, the country's international agricultural development research arm, along with MOISA, an interdisciplinary CIRAD-affiliated research unit focused on sustainable food systems. There, she encountered a "right-to-food" pilot in which Montpellier residents, half of whom live in poverty, pay a voluntary monthly amount on a sliding scale, from as little as 1 euro to 150 euros, and all receive a flat 100 euros back, redeemable at a handful of partner supermarkets. She also saw "social grocery stores" reaching rural areas through mobile markets, and digital platforms, letting neighbors pool their money to buy directly from local farmers.

Kennard also attended the European Ecological Economics Society Conference in Belgium, where she presented her food systems mapping research and learned about other local food models, specifically farmer-based cooperatives.

In Sheffield, Kennard gave a talk on community-engaged research methods and came away with insights from their local food network, ‘ShefFood,’ which is community-led rather than run by the university or city (though both have seats on its board). Leadership rotates every couple of years to keep it grounded in the community it serves.

From Campus to Community

Kennard's Atlanta work leans heavily on the students and community partners building it with her. This semester, she is working with incoming computer science Ph.D. student Tristan Daniel to automate her network map, scraping newsletters, news articles, and annual tax filings to keep the map's data updated in near-real time. Rhutvi Ahir, a master’s student in city and regional planning, has been working on integrating the systems map into a publicly available and interactive online platform.

Last semester, through a BBISS 2025 Sustainability Next Seed Grant project, Kennard, along with principal investigators Johannes Milz, Ingeborg Rocker, and Carl DiSalvo, professor in the School of Interactive Computing, convened 16 community and civic partners for a participatory design workshop mapping how food moves across metro Atlanta and where better data sharing could prevent waste. Drawing on feedback from that session, DiSalvo’s team is now exploring tools such as digital maps that show where surplus food, refrigerated trucks, and distribution sites are located, as well as a dedicated messaging system to coordinate what is now handled through ad hoc texts and calls.

This fall, DiSalvo’s graduate students in the interdisciplinary M.S. in Human-Computer Interaction program — from computing, design, and social science backgrounds — will turn those concepts into early prototypes to test with partners, giving students experience designing technology for real community needs rather than just commercial products.

DiSalvo says the core issue isn’t only a lack of food, but the difficulty of coordinating people, resources, and logistics at scale. “There’s so much need with food insecurity, and resources as well. It’s a coordination challenge. Most people didn’t get into this because they love logistics; they have a commitment to feeding people,” he said.

He credits Kennard with helping position Georgia Tech as a hub for food systems and community-engaged sustainability research. “Nicole’s work is important — not just her food systems research, but also the oversight she gives to community-based research. It’s amazing we have her as a colleague.”

DiSalvo isn't the only faculty collaborator. Sofía Pérez-Guzmán, an assistant professor in the School of Civil and Environmental Engineering and a BBISS Faculty Fellow, has partnered with Kennard to survey Atlanta residents in West End and citywide about how they access food. Their next step: building a tool based on what they learned.

"We're designing a decision-making tool that helps connect food locally, from producers to distributors and food access points in the community," Pérez-Guzmán said.

Not every connection requires a grant or a formal project. Through the networks she is building and her continued engagement, Kennard has linked a local consulting group with a co-op needing strategic guidance and introduced a farmers market organizer to a food rescue partner. Community partner Fresh Harvest even referenced her food system network map in a recent presentation to WABE radio. According to Kennard, it generated a lot of buzz, underscoring the appetite that Atlantans have for a shared picture of the food distribution ecosystem.

Two Maps, One Goal

Both of Kennard's maps are expected to go live by the end of the summer. The network map identifies the organizations working in the space and how they connect. The systems map, still being finalized, distills her interviews and engagement work into nine key thematic areas emerging as priorities for the city, along with competing visions of what a more resilient food system could look like.

The maps also anchor the research network Kennard co-leads with Emory University Associate Professor Emily Burchfield and agrifood systems researcher Kate Mundon-Dixon. The network has held two gatherings so far, one at a local hydroponic farm, where attendees added their own connections to the map. The network’s active listserv now includes more than 55 organizations.

For Kennard, the goal was never a single map or tool. It was building the foundation and the infrastructure that let everyone else act together. "I wanted to create this foundational research so that the academics and partners most poised to address specific challenges can create those teams and move forward together," she said.

She added that while most of her work is Atlanta-focused, it has implications for regional food access across Georgia. “A key insight that came from my systems mapping work is the need to connect rural and urban growers to move forward a statewide agenda for a resilient food system,” Kennard said. “My colleague at Emory, Emily Burchfield, is doing a lot more of the rural engagement, and we hope to align our work later.”

Everybody in Atlanta's food space is doing amazing work, she added, noting that, "If we can better align and coordinate under a shared vision and strategy, then we can actually move the needle on systems change, instead of just a few isolated things happening in different neighborhoods.”

But recent research from Georgia Tech’s School of Economics in the Ivan Allen College of Liberal Arts suggests adding an asterisk to earlier research that makes that conclusion, saying previous studies failed to account for one simple fact: people adapt. 

Georgia Tech economist Bobby Harris used a massive database of Fitbit step count data to measure how temperature shapes physical activity and found that extreme heat cuts step counts by 6% when compared to ideal weather. And while residents of the warmest regions cut their activity by an average of only 354 steps on days over 100 degrees, those living in the coldest regions cut theirs by 1,081, according to Harris’ analysis. 

To be fair, cold bites, too. On days that stay below freezing, people take roughly 1,000 fewer steps. That’s a 12% drop, enough to pack on a pound over the course of a typical Madison, Wisconsin winter, Harris found. 

But as the climate grows warmer, how humanity will respond to warmer temperatures remains a significant concern. In fact, earlier research projected that, by 2050, temperature-driven declines in physical activity could contribute to 500,000 premature deaths a year worldwide and annual productivity losses topping $2.4 billion. 

Projections like those typically assume everyone responds to heat the same way, with no capacity to adapt, Harris said.

The CAREER Award is NSF’s most prestigious honor for early-career faculty, recognizing researchers who demonstrate the potential to become leaders in both research and education.

Mahajan received the award for her research on designing energy-efficient, adaptive artificial intelligence (AI) datacenters through a cyber-physical approach that jointly considers AI software, computing hardware, and the physical state of the underlying infrastructure.

As AI models continue to grow in scale and complexity, they place increasing demands on every layer of datacenter infrastructure—from accelerators, memory, and networking to power delivery, cooling, and security. Yet these systems are often designed and optimized one layer at a time, limiting overall efficiency and adaptability.

Mahajan’s research reimagines AI datacenters as cyber-physical systems in which software, hardware, and physical operating conditions continuously inform one another.

“AI infrastructure should be designed around the real-time condition of the hardware, not just its specifications,” Mahajan said. “By making AI systems aware of the physical state of the infrastructure, we can build datacenters that are more efficient, adaptive, and resilient at scale.”

This award is part of NASA’s Space Technology Research Grants Program, which supports groundbreaking projects with the potential to transform space science and technology.

Through the three-year, $750,000 award, Mazumdar and her research team will develop laser-based methods to simultaneously measure temperature, chemical species, gas velocity, and other properties in the gases surrounding heat shield materials.

“We aim to implement our measurement techniques in arc jet or plasma jet facilities, like the ones at NASA, to assist with the evaluation of thermal protection systems for next-generation spacecraft,” Mazumdar said.

The project uses ultrafast lasers, which produce extremely short, high-intensity pulses. These pulses allow researchers to study the behavior of molecules on extremely short timescales and measure properties that can improve understanding of the gases surrounding a spacecraft during atmospheric entry.

Mazumdar said she and her students are excited about this project and hope it will help NASA develop new heat shields for spacecraft traveling to destinations such as Mars, Venus, and Titan.

A new study led by Francesca Storici, a professor in the School of Biological Sciences and faculty member of the Parker H. Petit Institute for Bioengineering and Bioscience, has uncovered an unexpected feature of human DNA linked to gene activity and the physical organization of DNA. The findings, published in Cell, could change how scientists think about DNA organization, transcription, and genome function. 

Through a Next Gen STEM (NGS) NASA Aerospace Skilled Technical Workforce Hubs (NAS_Hub) grant award, Georgia Tech will play a central role in addressing a critical labor shortage in the booming aerospace industry and enhance the state’s role as an aerospace industry leader in the global space economy.

Beginning this fall, the three-year, $1.5 million award will establish the Southeast Space Technology & Aerospace Readiness Skills (SE-STARS) Hub. The hub will expand opportunities for training and workforce readiness in high-demand technical careers in aerospace.
The SE-STARS Hub includes the Georgia Space Grant Consortium (GSGC), Georgia Tech’s Space Research Institute (SRI), the Georgia Tech Manufacturing Institute (GTMI), the Technical College System of Georgia (TCSG), Georgia Southern University, Georgia College and Career Academies, Georgia Aerospace & Defense Alliance (GADA), and select Georgia aerospace employers to support the growing aerospace industry and NASA missions.

Aerospace products are Georgia’s No. 1 export and the state has more than 800 companies supporting aviation, manufacturing, research, maintenance, repair, and operations.  Many aerospace and engineering positions rely on skilled technical workers whose training pathways do not require a four-year, or advanced degree. There are significant gaps in technical roles such as machinists, electronics technicians, test operators, and systems integrators. These shortages are driven by an aging workforce and a projected national shortfall of at least one million skilled technical workers by 2030. (National Academics of Sciences, Engineering, Medicine, 2025). The gap also stems from the rapid pace of technological advancement, where even current skills can quickly become obsolete if not constantly renewed.  All this combines to create an urgent need for training to support new and sustainable aerospace career pathways. 

Stephen Ruffin, interim chair of the Daniel Guggenheim School of Aerospace Engineering and GSGC director will serve as the principal investigator (PI).  Jud Ready, executive director of SRI; Lori Skillings, GSGC; Hossein Taheri, Georgia Southern University; and Steven Ferguson, GTMI, will serve as co-PIs. Jeffrey McNabb, a research engineer in Georgia Tech’s Aerospace Systems Design Lab (ASDL), will serve as the program manager, leading day-to-day operations and coordinating the project team.

"This initiative strengthens Georgia's position as a leader in aerospace innovation and manufacturing while providing new opportunities for students and industries across the state," said Ruffin.

Coordination between public education systems, industry, and workforce agencies can sometimes be limited. SE-STARS will act as a "hub" to bridge these gaps, connecting Georgia Tech and its specialized research institutes with TCSG’s 22 colleges and 88 campuses to provide statewide access to training.
“Another advantage of the program is the stronger network it creates,” said Ruffin. “Each organization in the SE-STARS team has unique capabilities but together we will strengthen the technical workforce pipeline across Georgia and the broader Southeast.”

The SE-STARS team will collaborate with industry partners to develop curriculum aligned with workforce needs. “The easily ported curricula we develop will be tailored for other institutions to adopt directly, creating a consistent foundation of skills and competencies that employers can universally expect from program graduates across Georgia,” Ready said.

Students will access training through a statewide network of technical colleges serving as regional instructional nodes, which offer flexible online options and hands-on paid apprenticeships to ensure broad geographic reach. 

The program also reaches K-12 and adult learners through career academies and specialized STEM labs, creating a structured, sustainable transition from early education to high-demand aerospace credentials. GTMI will support this work through its Advanced Manufacturing Pathways Program, which connects industry-informed training with pathways into high-demand advanced manufacturing careers.

“Georgia's expanding aerospace and space sectors are creating high-paying jobs and driving economic growth,” said Ruffin. “This program will help develop the skilled workforce needed to support that growth and Georgia’s competitiveness in the space economy.” 

As manufacturing systems become more connected, the cyberthreat grows with them. Saman Zonouz has spent years documenting how vulnerable smart manufacturing environments are. He’s an associate professor in the School of Cybersecurity and Privacy and the School of Electrical and Computer Engineering, where he co-leads the Cyber-Physical Security Lab with Raheem Beyah, Georgia Tech’s provost and executive vice president for Academic Affairs. 

Instead of becoming steadily stickier as they are pulled apart, soft hydrogels first become less adhesive and then more adhesive as the pulling speed increases, revealing a previously unknown "sweet spot" where detachment is easier. The discovery challenges a long-held assumption in adhesion mechanics and reveals a new physical mechanism that governs how soft materials attach and detach.

"We expected the adhesion to increase continuously with pulling speed, as predicted by classical theories," said Yuhang Hu, associate professor in the George W. Woodruff School of Mechanical Engineering and the School of Chemical and Biomolecular Engineering. "Instead, we found the exact opposite over a broad range of speeds. That told us there had to be a completely different physical process at work."

"One of the goals of the program is to give students the time and support needed to make meaningful progress on their dissertation research while helping them understand the broader policy, economic, and societal implications of their work," said Laura Taylor, director of EPIcenter.

The stipends enable participants to focus exclusively on clearly defined research goals. The program also supports peer discussions, communication training, and interdisciplinary learning opportunities designed to strengthen both their research and professional development.

This year's cohort explored topics ranging from electricity markets and air pollution to critical mineral supply chains and grid modernization, highlighting the breadth of energy-related research taking place across Georgia Tech.

Exploring Complex Energy Challenges

Ana Mazmishvili, who studies environmental and energy economics, used the summer to examine how climate policies affect communities across state lines.

"My research measures who is actually exposed to pollution from power plants when some states adopt climate regulations to cut emissions while neighboring regions do not," Mazmishvili said. "Because air doesn't stop at state borders, the key question is what happens once the pollution is emitted, and who ends up breathing it."

Her work focuses on the Regional Greenhouse Gas Initiative (RGGI), a cap-and-trade program in the Northeast, and investigates whether the benefits and burdens of emissions reductions are distributed equitably between regulated and neighboring states.

Mazmishvili said the program provided valuable time to focus on her job-market paper, a central component of her dissertation.

"The regular meetings with the program director and other fellows create useful accountability checkpoints and let me hear perspectives from people in very different fields," she said. "We're also learning how to make academic research understandable to a general audience, a skill I expect to use well past this summer."

Industrial and systems engineering doctoral student Faeze Fahimi Aghda spent the summer developing an optimization model for the U.S. gallium supply chain, a critical component of many advanced technologies.

Her research uses mathematical modeling to examine where and when domestic gallium processing facilities should be established under the threat of supply disruptions.

"Working on my research through EPIcenter has taught me to look at my problem from a policy point of view rather than focusing only on the math," Fahimi Aghda said. "The feedback within the meetings helped me improve my model."

Ryan Anthony, in the Jimmy and Rosalynn Carter School of Public Policy, explored how one of the largest oil shocks in U.S. history affected electricity customers and whether utility ownership influenced the impact on consumers.

"So far, my research suggests that it mattered a lot,” Anthony said. “Municipal utilities held rates down and absorbed many of the costs, while private, investor-owned utilities passed more costs through to their customers."

Anthony said the program provided critical support for the archival research required for the project.

"My project depends on data that only exists in old government reports, and that kind of archival work is difficult to fund," he said. "EPIcenter gave me the time and space to do it properly."

Connecting Research to Real-World Impact

For Samin Alipour, the summer provided an opportunity to explore how electric grids can adapt to growing numbers of distributed energy resources.

"Most electric distribution systems were built like one-way roads, carrying power from a substation to homes and businesses," Alipour said. "Rooftop solar, batteries, and electric vehicles are turning those roads into two-way systems."

Her research examines how these emerging technologies can be coordinated to increase grid flexibility and clean energy adoption while maintaining safety and reliability and ensuring that costs and benefits are distributed fairly.

With support from EPIcenter, Alipour focused on the economic and policy dimensions of those challenges. "I did not want my research to remain only a technical model," she said. "The program has helped me connect the technical results of my dissertation to economic value, reliability, equity and compensation policy."

One study developed during the summer was accepted for presentation at a specialized power systems conference, an achievement Alipour credits in part to the opportunity to focus on the broader implications of her work.

Building the Next Generation of Energy Scholars

Beyond advancing individual research projects, the Summer Research Program encourages students to engage with colleagues from different disciplines and develop skills for communicating complex ideas to broader audiences.

“Through regular cohort meetings, participants build a community of accountability, discuss research challenges, explore interdisciplinary energy topics, and develop communication skills,” said Gil Gonzalez, program support coordinator for EPIcenter. “Students also write a research-focused blog post for EPIcenter and present their work at the program's fall workshop, which allows them to share their research with the broader Georgia Tech energy community.”

As EPIcenter continues to support interdisciplinary energy scholarship at Georgia Tech, the Summer Research Program equips future leaders with the tools to address complex energy challenges through technological innovation, informed policy, and economic analysis.

Launched in 2025, INNS serves as a hub for neuroscience and neurotechnology research, connecting researchers across disciplines to advance discovery, innovation, and societal impact.

“A core part of INNS's mission is helping people find one another, connect around shared interests, and build something bigger than they could accomplish alone,” says Executive Director Christopher Rozell. “Simon has spent his career bringing together people, perspectives, and disciplines to tackle complex challenges. I can't think of a better person to help lead our interdisciplinary research efforts and support the next generation of collaborative neuroscience research.”

A longtime leader in Georgia Tech's neuroscience community, Sponberg helped shape the institute's early foundations through the Neuro Next Initiative, which evolved into INNS. As associate director, he will help guide research strategy, foster new collaborations, and support interdisciplinary work across the neuroscience ecosystem.

“Neuro-related research touches so many fields that we inevitably have a problem of finding all the potential right people and opportunities to tap into,” he said. “A core responsibility of this role is helping catalyze the ideas of new teams of talented researchers, educators, and trainees from inception to realization.”

Sponberg is the Glen Robinson Professor in Complex Systems with appointments in the School of Physics and the School of Biological Sciences, where he directs the Agile Systems Lab. His work also connects him to the Institute for Bioengineering and Bioscience (IBB) and the Institute for Robotics and Intelligent Machines (IRIM), underscoring the cross-disciplinary approach that defines both his research and leadership.

Since joining Georgia Tech in 2014, he has built a highly collaborative research program spanning neuroscience, biology, physics, engineering, and robotics while helping foster interdisciplinary connections across campus. He currently leads a Multidisciplinary University Research Initiative (MURI) that brings together neuroscientists and engineers from five universities to understand how brains achieve fast, flexible perception and decision-making in complex sensory environments. He also co-leads the Integrative Movement Sciences Institute, an NSF Biological Integration Institute focused on understanding movement and muscle function across scales.

His contributions have been recognized through numerous honors, including a Young Investigator Award from the International Society for Neuroethology, a Klingenstein-Simons Fellowship in the Neurosciences, and the Leddy Family Dean’s Faculty Excellence Award.

As associate director, Sponberg will focus on helping researchers identify new opportunities for connection and collaboration. In addition to overseeing seed funding programs, he hopes to create pathways for researchers to build teams, access support resources, pursue ambitious interdisciplinary research ideas, and team with Georgia Tech’s undergraduate and graduate neuroscience degree programs.

“I look forward to being a resource for our community when people are looking for help in building teams or finding opportunities to support their ideas,” he said. “Bring your best ideas and please reach out if you want to talk about ideas in the interdisciplinary neuro space that you want to see realized.”
 

Counterfeit and out-of-spec components are entering U.S. defense supply chains through thousands of small and midsized suppliers that make up the lower tiers of the industrial base. Researchers at the Georgia Tech Manufacturing Institute (GTMI) say the fix isn't just better parts, but better proof: verified digital records, secured against tampering, that travel with each component from raw material to installation.   

The U.S. has seen its printed circuit board market share plummet to 4% while becoming dangerously dependent on foreign rare earth processing. Now, with global supply chains fracturing, defense industrial capacity under pressure, and adversaries looking to dominate advanced production, the country is in a race to rebuild — and to rebuild smarter. 

The Air Quality Index (AQI) measures how clean or polluted the air is. A healthy AQI is between zero and 50, but when wildfire smoke blows in and settles over cities, the AQI can reach levels of 500 or more. Poor air quality changes where and how people spend their time and money, reduces productivity (even for those working indoors), and increases healthcare costs.

“Environmental regulations like the Clean Air Act dramatically improved our air quality over the past 40 years, but as wildfire season becomes the new normal, wildfire smoke is eroding those gains,” Wichman said. According to recent research, wildfire smoke has erased about a quarter of the progress made over previous decades, and more than half in many western states.

From a single Atlanta church to a growing network across the Southeast, Georgia Tech engineer Sofía Pérez-Guzmán is connecting communities and researchers to support resilience in extreme weather events. 

For researchers in Georgia Tech's Cyber-Physical Security (CPSec) Lab, however, the vulnerabilities behind many of these incidents are far from new.

Associate Professor Saman Zonouz leads the CPSec Lab and has studied programmable logic controllers (PLCs) for years. These devices automate critical infrastructure, including water treatment facilities, power grids, manufacturing plants, and transportation systems. The lab’s work has revealed widespread internet exposure and software vulnerabilities that leave many industrial control systems vulnerable to cyberattacks.

"Out of the 16 critical infrastructure sectors defined by the Cybersecurity and Infrastructure Security Agency, four are considered lifelines," Zonouz said. "Of those four, communications, energy, transportation, and water, the water sector is the most vulnerable, which is why it is so often targeted."

PLCs serve as the brains of industrial operations, monitoring sensors and controlling equipment that keep essential services operational.

"Imagine you have a thermostat that controls the temperature of your house. That is a type of controller," Zonouz explained. "The professional version does the same thing in industry."

When these controllers are directly accessible from the internet, attackers can exploit them to disrupt operations, manipulate industrial processes, or interfere with the systems that deliver essential services. Controllers may be intentionally exposed to allow operators to monitor equipment remotely. They can also be unintentionally accessible online because of configuration errors.

However, internet exposure is only part of the problem.

The CPSec Lab maintains a collection of PLCs that researchers reverse engineer to better understand their firmware, communication protocols, and security weaknesses. Their research has found that many controllers contain vulnerabilities that attackers can exploit once they gain access.

"Not only can the attackers see the house they want to rob, but the doors are also left unlocked," Zonouz said.

In 2024, Zonouz and his collaborators presented PLCHound at the ACM Conference on Computer and Communications Security (CCS), introducing an automated system that identifies internet-connected PLCs hidden within massive internet-scale datasets collected by services such as Shodan and Censys. The work was led by Ph.D. student Ryan Pickren. Provost and Executive Vice President for Academic Affairs Raheem Beyah, Assistant Professor Frank Li, and Research Scientist Animesh Chhotaray are co-authors of the study. 

Rather than relying on traditional scanning techniques, PLCHound identifies subtle network signatures that reveal industrial devices that prior methods often missed. Using the system, the researchers conducted one of the largest studies of publicly reachable PLCs from major manufacturers.

Their findings showed that previous estimates undercounted the number of internet-accessible industrial controllers by as much as 37 times. Even more concerning, nearly 96% of the identified devices exposed protocols linked to recently disclosed critical vulnerabilities.

The researchers did more than document the problem. After identifying exposed devices, the team launched a large-scale notification campaign, contacting more than 7,000 industrial operators to alert them that their systems appeared vulnerable. The effort enabled many organizations to investigate and address security issues before they could be exploited.

The recent attacks on municipal water systems reinforce concerns researchers have raised for years: many critical infrastructure operators continue to rely on operational technology designed primarily for reliability and performance rather than for cybersecurity.

Improving those defenses, Zonouz said, will require more than simply patching individual vulnerabilities.

The researchers cite the energy sector as a model. Compared with other critical infrastructure sectors, electric utilities generally operate under more mature cybersecurity requirements and undergo routine compliance audits, providing organizations with greater visibility into the devices connected to their networks and the risks they pose.

Implementing those improvements will not be easy. Many municipal water utilities operate with limited budgets and aging infrastructure, leaving little funding available for cybersecurity investments. As attacks on critical infrastructure become more frequent, the researchers argue that gaining visibility into operational technology assets and strengthening oversight are essential first steps to protect the systems communities rely on every day.

The CPSec Lab is a collaborative laboratory within the School of Cybersecurity and Privacy as well as the School of Electrical and Computer Engineering.
