Faculty Profile

BIOGRAPHY

  • PhD (2013), MSCE (2011), Civil Engineering (Geosystems Engineering), Georgia Tech
  • MS, BS, Civil Engineering (Geotechnical Engineering), Tongji University

Sheng Dai is an Assistant Professor in the School of Civil and Environmental Engineering at Georgia Institute of Technology in Atlanta, Georgia, USA. He earned his BS and MS degrees in civil engineering from Tongji University, Shanghai, China. In 2008, he joined the geosystems group at Georgia Tech, where he served as the president of the Geotechnical Society (2011-2012) and earned his MSCE and Ph.D. degrees in civil engineering in 2011 and 2013. He then worked at the National Energy Technology Laboratory of U.S. Department of Energy before joining the faculty at Georgia Tech in 2015.

Dr. Dai has strong research and teaching interests in the energy geoengineering. His group study the fundamental physical properties and bio-thermo-hydro-mechanical-chemical coupled processes in soils and rocks at elevated pressure and temperature conditions, with applications primarily in the areas of subsurface energy and resources recovery. His group explores the scientific foundations of geomaterial behavior through wave characterization, imaging techniques, and the development of unprecedented devices (including testing theories and bio-inspired sensors). His group recently get involved in methane hydrates research at NETL/DOE and the NSF-funded Engineering Research Center (ERC) for Bio-mediated and Bio-Inspired Geotechnics (CBBG).
