He received his Ph.D. degree in Civil Engineering from Texas A&M University. He has been teaching and conducting research in the field of geotechnical engineering since 1992. His studies focus on development of advanced laboratory techniques to rapidly characterize geomaterials, constitutive modeling coupled hydro-mechanical behavior of unsaturated soils, numerical modeling of climate-soil-structure interaction, slope stability analysis, soil stabilization and ground improvement, and frozen ground engineering. He was one of the two speakers of ASCE Geo-Institute Unsaturated Soils Committee Webinar on “Introduction to Constitutive Modeling of Unsaturated Soils.”
