Faculty Profile

BIOGRAPHY

  • Ph.D., MSCE, Georgia Institute of Technology
  • MS, BS, Tongji University

Sheng Dai, Ph.D., P.E., is an Associate Professor in geosystems engineering at Georgia Tech. After graduating with Ph.D. from Georgia Tech, he worked as an ORISE postdoc at the National Energy Technology Laboratory, before joining the faculty in the School of Civil and Environmental Engineering at Georgia Tech in 2015. 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's research group strives to advance the fundamental understanding and predictive capabilities of geomechanics for energy and the environment, including areas of subsurface energy recovery and storage, granular mechanics, and subsurface multiphase flow. Current projects in the group are hydrate-bearing sediments, microbial effects in porous media, bio-inspired drilling, granular flow of compressible particles, and seismic signal processing. 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, Geomechanics for Energy and the Environment, and Advances in Geo-Energy Research, 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.
