Sheng Dai

Brief Biography: 

Sheng Dai, Ph.D., is an Assistant Professor in geosystems engineering at Georgia Tech. He received BS and MS degrees in civil engineering from Tongji University, China, and MSCE and Ph.D. degrees in civil engineering (geosystems engineering program, minor in mathematical geophysics) from Georgia Tech. After graduation, he worked in the Predictive Geosciences Division at the National Energy Technology Laboratory of the U.S. Department of Energy. In 2015, he returned to Georgia Tech and joined the faculty in the School of Civil and Environmental Engineering. He is an affiliated faculty in the Ocean Science and Engineering program, the Strategic Energy Institute, and holds a courtesy appointment at the School of Earth and Atmospheric Sciences at Georgia Tech.

Dr. Dai has strong research and teaching interests in soil behavior, geomaterials characterization, bio-inspired geotechnics, subsurface geomechanics, energy geotechnics, and flow in porous media. His group develops innovative testing techniques in combination with advanced numerical modeling to study fundamental properties and BTHMC-coupled processes in soils and rocks at elevated pressure and temperature conditions. His research has been funded by DOE, NSF, NASA, NETL, IDOT, AECOM, and Leidos. 

Dr. Dai has been recognized for his research and teaching, including being a recipient of the NSF CAREER award, 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 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.
