About Me

Prior to joining the faculty of civil engineering at Widener University in 2013, I worked as a senior engineer for a consulting firm and a senior research associate at the Louisiana Transportation Research Center in the areas of geotechnical engineering, transportation infrastructure and materials. I currently serve on two standing committees (AFD20 and AFS60) of the Transportation Research Board of National Academies. I teach courses in geotechnical engineering at Widener.

I received my undergraduate degree in mining and geotechnical engineering from Central South University, technical engineering from Central South University, China in 2002, my MS in civil engineering from West Virginia University in 2006, and PhD in civil engineering from Pennsylvania State University in 2011.

Research Interests

My research interests lie in the general areas of geotechnical and infrastructure engineering. My recent work focuses on the instrumentation and monitoring of transportation infrastructure as well as characterization and effective use of new and sustainable materials for geotechnical and transportation projects.

The overall goal of my research is to address pressing issues related to the nation’s aging transportation infrastructure through innovative and practical ideas and technologies.
