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.

Bjarne Kreitz is an incoming Assistant Professor of Chemical Engineering at Georgia Tech. Kreitz received a B.Sc. and M.Sc. in Chemical Engineering from Clausthal University of Technology (Germany). He obtained his Dr.-Ing. in Chemical Engineering from Clausthal University of Technology under the supervision of Prof. Thomas Turek, working on the microkinetic investigation of the transient methanation with experiments and multiscale modeling. 

Kreitz conducted postdoctoral work at Brown University with Prof. Franklin Goldsmith with a Feodor Lynen Postdoctoral Scholarship from the Alexander von Humboldt Foundation. Before joining Brown, he worked briefly as a postdoc at the Karlsruhe Institute of Technology (Germany) in the group of Prof. Olaf Deutschmann.

Erin L. Ratcliff is a Full Professor in the School of Materials Science and Engineering and the School of Chemistry and Biochemistry at the Georgia Institute of Technology and holds a joint appointment at the National Renewable Energy Laboratory.  Prof. Ratliff is also the Associate Director of Scientific Continuity for Director of the currently funded Energy Frontier Research Center (EFRC) entitled “Center for Soft PhotoElectroChemical Systems (SPECS)”, a center which she directed at her prior appointment at University of Arizona.  

Her group “Laboratory for Interface Science for Printable Electronic Materials” uses a combination of applications and devices with electrochemistry, spectroscopies, microscopies, and synchrotron-based techniques to understand fundamental structure-property relationships of next-generation materials for energy conversion and storage and biosensing. Materials of interest include metal halide perovskites, π-conjugated materials, colloidal quantum dots, and metal oxides. Current research is focused on mechanisms of electron transfer and transport across interfaces, including semiconductor/electrolyte interfaces and durability of printable electronic materials.

Her research program has been funded by the Department of Energy Basic Energy Sciences, the Solar Energy Technology Office, Office of Naval Research, National Science Foundation, and the Nano Bio Materials Consortium.

Scott Danielsen is an Assistant Professor in the School of Materials Science and Engineering at the Georgia Institute of Technology. He obtained his Ph.D. in chemical engineering at the University of California, Santa Barbara in 2018 and his B.S.E. in chemical and biomolecular engineering at the University of Pennsylvania in 2014. He then spent five years as a postdoctoral associate at Duke University and as a visiting scholar at the University of North Carolina School of Medicine from 2019-2023. 

Prof. Danielsen’s group uses a combination of theoretical, computational, and experimental methods to reveal structure–property–processing relationships of soft materials. Their current primary research interests are the structure and dynamics of nonideal structured fluids, particularly polymer gels and biological fluids, with a focus on designing new materials and processing conditions for functional materials.

Sheng Dai, Ph.D., P.E., earned his degrees from Tongji University and Georgia Tech. He worked as an ORISE postdoc at the National Energy Technology Laboratory of the U.S. Department of Energy, and returned to Georgia Tech as a faculty member in 2015. He is currently an associate professor in the School of Civil and Environmental Engineering, Ocean Science and Engineering. and holds a courtesy appointment at the School of Earth and Atmospheric Sciences at Georgia Tech.

Dr. Dai's group addresses emerging energy and environment challenges through studying subsurface geomechanics, geomaterials characterization, energy geotechnics, bio-inspired geotechnics, flow in porous media, and granular dynamics. His research has been funded by federal funding agencies (DOE, NSF, NASA, DOT), national labs (INL, NETL), and industry (AECOM, GTI, Leidos).  Dr. Dai has been recognized for his research and teaching, including being a recipient of the NSF CAREER award, the ORISE Fellowship, the Bill Schutz Junior Faculty Teaching Award, and the Class of 1969 Teaching Fellows at Georgia Tech.

He is an associated editor of the Journal of Geophysical Research: Solid Earth and Advances in Geo-Energy Research, an editorial advisor of Geomechanics for Energy and Environment, and serves on the Pressure Core Advisory Board for U.S. Geological Survey, the GOM2 Marine Test Technical Advisory Committee for UT/DOE, the National Gas Hydrate Program for NETL, and the Task Force Leader of TC308 Energy Geotechnics of ISSMGE.
