I am a professor in Economics and Computation at the Department of Computer Science, University of Liverpool, United Kingdom.

Before joining Liverpool in 2010, I taught at City University of Hong Kong and York University. I did my (NSERC international fellowship) postdoc at Simon Fraser University with Tiko Kameda and Pavel Hell, PhD at Stanford University with Christos Papadimitriou, MSc at Chinese Academy of Sciences with Yonjin Zhu, and B.Eng at Tsinghua University.

RESEARCH: My research focus is on Algorithmic Game Theory, which deals with computational issue on fundamental economic problems such as Nash equilibrium, resource pricing and allocation protocols such as auction and market equilibrium, as well as theory and practice in Internet market design. This methodology integrates Algorithms with micro- and macro-economics, information economics, and has become a powerful tool in our understanding of the Internet and the practice of e-Commerce.

TEACHING: I have taught most computer science classes in algorithm related topics. In addition, I designed and taught graduated courses in web search, Internet market protocols. I gave lectures in special topics at summer schools such as equilibrium computation at Fudan University, sponsored search auctions at Karlsruhe University, online algorithms at Zhejiang University. I also taught short courses in algorithms at visiting institutes such as Kyoto University, Peking University, Tsinghua University, and Xiamen University.

I have been an ACM Fellow since 2008, an IFIP TC1 member since 2007.
I have been program committee members of major theory conferences such as COCOON, ESA, FSTTCS, ICALP, ISAAC, STOC, and algorithmic game theory related conferences: ACM-EC, SAGT, WINE.
