Materials research is foundational to the creation of new technologies and economic growth in a variety of areas, which include transportation, energy storage and generation, recyclability, information and communication, infrastructure, and healthcare. To facilitate advances in materials research, Georgia Tech’s Institute for Materials (IMat) brings together researchers from academia and industry to facilitate interdisciplinary collaborations in materials research to address the opportunities and challenges in these areas.

To enable this research, IMat leadership has supported strategic interdisciplinary initiatives since 2021. Each initiative has a dedicated faculty lead to guide the initiative and prepare teams to compete for mid- and large-scale, multi-investigator research centers with academic, national laboratory, and industry partners. Initiative leads also work to increase the campus’ collaborative spirit by working with other Interdisciplinary Research Institutes, campus units, and the Georgia Tech Research Institute to design and support research programs. Initiative leads serve for one academic year and may be considered for renewal based on their progress in achieving community-building goals and their impact on IMat and the materials innovation ecosystem at Georgia Tech.

“The goal of our initiative lead program is to provide support for these strategic interdisciplinary research areas,” said IMat Executive Director Eric Vogel. “Now that we are in the third year of the program, we have seen significant growth in many of the initiatives we have supported, including batteries and energy storage and materials laboratories for the future.”

Materials for Energy Storage Initiative to Become Georgia Tech Advanced Battery Center

Matthew McDowell has served as an IMat initiative lead in Materials for Energy Storage, a joint initiative with the Strategic Energy Institute (SEI), since the program began in 2021. With the nation’s increased focus on electric vehicles, battery storage technologies have gained significant attention since McDowell launched his initiative. In addition, the state of Georgia is becoming the epicenter of the battery belt of the Southeast, with more than $25 billion invested or announced in EV-related research in the past three years. The Materials for Energy Storage Initiative has worked to highlight Georgia Tech’s strong energy storage research community and how it can help shape the development of next-generation energy storage devices. In 2023, McDowell and his team hosted Georgia Tech Battery Day, a sold-out event that brought together more than 230 energy researchers and industry representatives to advance energy storage technologies.

This year, the Materials for Energy Storage Initiative will become the Georgia Tech Advanced Battery Center, with McDowell and Gleb Yushin as co-directors. The new center will build community at Georgia Tech, work to enhance relationships with industrial partners, and create a new battery manufacturing facility on Georgia Tech’s campus. The Advanced Battery Center is the latest initiative to gain external funding and become a center, in addition to the Center for Organic Photonics and Electronics and the Georgia AI Manufacturing coalition led by former IMat Initiative Lead Aaron Stebner.

Meet the 2023-24 IMat Initiative Leads

As an IMat initiative lead, Losego will help build a community at Georgia Tech that works toward developing autonomous and intelligent systems (robots) that execute physical experiments — processing, characterizing, and measuring the properties of materials — and then uses this knowledge to iteratively and intelligently execute subsequent experiments that produce new knowledge about process-structure-property relations, which inform materials discovery and design. He also hopes to learn what technical questions, training opportunities, or other incentives would compel Georgia Tech roboticists to collaborate with materials scientists to develop autonomous materials discovery systems and what the Georgia Tech materials community can do with emerging, inexpensive, and simple-to-use robotics systems to drive autonomous materials discovery.

Macromolecular Materials at Biotic and Abiotic Interfaces

Valeria Tohver Milam is an associate professor and MSE Faculty Fellow in MSE. She holds a B.S. from the University of Florida, and an M.S. and Ph.D. from the University of Illinois Urbana-Champaign, all in materials science and engineering.

Quantum Responses of Topological and Magnetic Matter | Zhigang Jiang
Zhigang Jiang is a professor in the School of Physics. He holds a B.S. in physics from Beijing University and a Ph.D. in physics from Northwestern University. He was also a postdoctoral research associate at Columbia University jointly with Princeton University and NHMFL from 2005 to 2008. His research interests are in the quantum transport and infrared optical properties of topological and magnetic materials. His current projects include infrared magneto-spectroscopy of topological semimetals, band-engineering topological phases in metamorphic InAsSb ordered alloys, and developing new materials for portable, real-time radiation monitoring devices.

The goals of this initiative are twofold: first, to anchor, develop, and promote the community of researchers working on the fundamental magnetic properties of quantum materials. And second, to connect these researchers to application-centric initiatives led by other science or engineering colleagues across Georgia Tech. The focus will be on fundamental research progress in topological and magnetic matter and to communicate their importance, relevance, and significance to Georgia Tech’s research audience. In addition, this initiative aims to leverage fundamental discoveries in quantum materials and explore how they can be translated in their own right into quantum systems with new functionalities for spintronics, qubits, and electronic devices.

Materials in Extreme Environments | Richard W. Neu
Richard W. Neu is a professor in the Woodruff School of Mechanical Engineering and the School of Materials Science and Engineering. His research involves the understanding and prediction of the fatigue behavior of materials and closely related topics, typically when the material must resist degradation and failure in harsh environments. He has investigated a broad range of structural materials, including steels, titanium alloys, nickel-base superalloys, metal matrix composites, molybdenum alloys, high entropy alloys, medical device materials, and solder alloys used in electronic packaging. 

Neu served as an initiative lead in 2022 and will continue in this role in 2023. He will continue to engage and build an interdisciplinary research community to address the complex issues associated with new materials in extreme environments. These environments include high temperature, high pressure, corrosive, wear/erosion, cyclic loading, high-rate impacts, and radiation. In harsh environments, materials are continuously evolving and deforming, presenting a roadblock in advancing engineering systems due to the uncertainty in the performance of new materials or new process methods such as additive manufacturing. Managing this risk by predicting the uncertainties, both internal to the material (its structure feature) and external environment, is an important consideration that materials engineering must address.

Organic Photonics and Electronics | Jason Azoulay

Jason Azoulay is an associate professor and Georgia Research Alliance Vasser-Woolley Chair in Optoelectronics in the School of Chemistry and Biochemistry, with a joint appointment in the School of Materials Science and Engineering.
