I am an assistant professor in the Computer Science Department of Columbia University. Before joining Columbia, I was a postdoctoral researcher at the Institute for Advanced Study, Princeton University
and University of Southern California. 

I studied in Tsinghua University (B.S. in Physics / Maths 03 and Ph.D. in Computer Science 07). My advisor was Professor Bo Zhang, and I was a member of the Institute for Theoretical Computer Science led by Professor Andrew Chi-Chih Yao.

My research interests lie in Algorithmic Game Theory / Economics
and Complexity Theory (CV). My research is currently supported by

an NSF CAREER award, a Sloan research fellowship, and start-up from

Columbia University.
