Steve WaiChing Sun obtained his B.S. from UC Davis; M.S. in civil engineering (geomechanics) from Stanford; M.A. degree from Princeton; and Ph.D. in theoretical and applied mechanics from Northwestern. Prior to joining Columbia, he was a senior member of technical staff in the mechanics of materials department at Sandia National Laboratories (Livermore, CA).
Dr. Sun works in the fields of theoretical and computational solid mechanics, poromechanics and multiscale modeling of fully coupled multiphysical systems. The objective of his research is to advance the understanding on multiphase materials under extreme conditions and enhance predictive capabilities for related engineering applications, including geological carbon sequestration, hydraulic fracture and soil liquefaction. His research includes the development of solution techniques for coupled deformation-diffusion in non-isothermal saturated and unsaturated porous media, formulations of stabilized mixed-field finite element model for large deformation multiphysics problems, modeling and homogenization of mechanical and hydraulic properties of porous media from CT images, applications of mathematical tools, such as graph theory, Lie algebra, and combined deterministic-stochastic method, for modern engineering problems.
