Valerie Thomas is the Anderson-Interface Chair of Natural Systems and Professor in the H. Milton School of Industrial and Systems Engineering, with a joint appointment in the School of Public Policy. 

Dr. Thomas's research interests are energy and materials efficiency, sustainability, industrial ecology, technology assessment, international security, and science and technology policy. Current research projects include low carbon transportation fuels, carbon capture, building construction, and electricity system development. Dr. Thomas is a Fellow of the American Association for the Advancement of Science, and of the American Physical Society. She has been an American Physical Society Congressional Science Fellow, a Member of the U.S. EPA Science Advisory Board, and a Member of the USDA/DOE Biomass Research and Development Technical Advisory Committee. 

She has worked at Princeton University in the Princeton Environmental Institute and in the Center for Energy and Environmental Studies, and at Carnegie Mellon University in the Department of Engineering and Public Policy.

Dr. Thomas received a B. A. in physics from Swarthmore College and a Ph.D. in theoretical physics from Cornell University.

Josiah Hester works broadly in computer engineering, with a special focus on wearable devices, edge computing, and cyber-physical systems. His Ph.D. work focused on energy harvesting and battery-free devices that failed intermittentently. He now focuses on sustainable approaches to computing, via designing health wearables, interactive devices, and large-scale sensing for conservation. 
   
His work in health is focused on increasing accessibility and lowering the burden of getting preventive and acute healthcare. In both situations, he designs low-burden, high-fidelity wearable devices that monitor aspects of physiology and behavior, and use machine learning techniques to suggest or deliver adaptive and in-situ interventions ranging from pharmacological to behavioral. 
   
His work is supported by multiple grants from the NSF, NIH, and DARPA. He was named a Sloan Fellow in Computer Science and won his NSF CAREER in 2022. He was named one of Popular Science's Brilliant Ten, won the American Indian Science and Engineering Society Most Promising Scientist/Engineer Award, and the 3M Non-tenured Faculty Award in 2021. His work has been featured in the Wall Street Journal, Scientific American, BBC, Popular Science, Communications of the ACM, and the Guinness Book of World Records, among many others.

The Tong Lab tackles challenges in the interdisciplinary areas of bioresource engineering and sustainable chemistry. We develop innovative technologies for producing chemicals, materials, energy, and fuels from renewable resources.

Current research interests include:

• Functional biomaterials for high-efficiency circular economy
• Platform chemicals and hydrocarbon fuels from renewable resources
• Sustainable process control and modeling
• Nano-biomaterial synthesis and self-assembling
• Polymer degradation and recycling

Disciplines:

• Materials and Nanotechnology

• Energy and Sustainability

David Flaherty, PhD is a Professor in the School of Chemical and Biomolecular Engineering at Georgia Tech since June 2023 (starting Summer 2023, previously at the University of Illinois, Urbana-Champaign). His research focuses on developing the science and application of catalysis in the pursuit of sustainability. In recent years, his group’s contributions have been featured in Science, Nature Catalysis, Journal of the American Chemical Society, ACS Catalysis, Journal of Catalysis and other prestigious journals. Dr. Flaherty has received several recognitions for excellence and innovation in catalysis including the Eastman Foundation Distinguished Lecturer in Catalysis, Department of Energy Early Career Award, and the National Science Foundation CAREER Award. Dr. Flaherty engages frequently with industry to translate the groups scientific achievements from the lab into practice. Through university-industry partnerships, the group has filed multiple patents disclosing synthesis of catalytic materials and development of processes. Beyond his research activities, Dr. Flaherty enjoys teaching topics in chemical engineering in the classroom (kinetics, separations, transport, reaction engineering) and mentoring the next generation of research leaders and educators.

Prof. Flaherty received his B.S. in Chemical Engineering from the University of California, Berkeley and his Ph.D. in Chemical Engineering from the University of Texas at Austin under the direction of Prof. C. Buddie Mullins. He conducted postdoctoral work at the University of California, Berkeley with Prof. Enrique Iglesia.
