She served two terms (2010-2017) as a Presidential appointee and regulator on the Board of Directors of the Tennessee Valley Authority, the nation’s largest public power provider. From 2014-2018 she served on DOE’s Electricity Advisory Committee, where she led the Smart Grid Subcommittee.

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. 

Nian Liu began as an Assistant Professor at Georgia Institute of Technology, School of Chemical and Biomolecular Engineering in January 2017. He received his B.S. in 2009 from Fudan University (China), and Ph.D. in 2014 from Stanford University, where he worked with Prof. Yi Cui on the structure design for Si anodes for high-energy Li-ion batteries. In 2014-2016, he worked with Prof. Steven Chu at Stanford University as a postdoc, where he developed in situ optical microscopy to probe beam-sensitive battery reactions. Dr. Liu 's lab at Georgia Tech is broadly interested in the combination of nanomaterials, electrochemistry, and light microscopy for understanding and addressing the global energy challenges. Dr. Liu is the recipient of the Electrochemical Society (ECS) Daniel Cubicciotti Award (2014) and American Chemical Society (ACS) Division of Inorganic Chemistry Young Investigator Award (2015).

Fedorov's background is in thermal/fluid sciences, chemical reaction engineering as well as in applied mathematics. His laboratory works at the intersection between mechanical and chemical engineering and solid state physics and analytical chemistry with the focus on portable/ distributed power generation with synergetic CO₂ capture; thermal management of high power dissipation devices and electronics cooling; special surfaces and nanostructured interfaces for catalysis, heat and moisture management; and development of novel bioanalytical instrumentation and chemical sensors. Fedorov joined Georgia Tech in 2000 as an assistant professor after finishing his postdoctoral work at Purdue University.

Tim Lieuwen is the interim executive vice president for Research (EVPR) at the Georgia Institute of Technology. In this role, he oversees the Institute’s $1.37 billion portfolio of research, economic development, and sponsored activities. This includes leadership of the Georgia Tech Research Institute (GTRI), the Enterprise Innovation Institute, nine interdisciplinary research institutes (IRIs), and related research administrative support units.

In his 25-plus years at Georgia Tech, Lieuwen earned his master's and Ph.D. degrees in mechanical engineering (1996 and 1999, respectively) and has held multiple leadership positions. He has been the executive director of the Strategic Energy Institute (SEI) since 2012 and began serving as the interim chair of the Daniel Guggenheim School of Aerospace Engineering in 2023.

Lieuwen has received numerous honors and recognition for his work in clean energy systems and policy, national security, and regional economic development. Additionally, he has been awarded the titles of Regents’ Professor and the David S. Lewis, Jr. Chair in AE. He is also a member of the National Academy of Engineering and is a fellow of the American Society of Mechanical Engineers and the American Institute of Aeronautics and Astronautics.
