My current research focuses on the interdisciplinary topics between AI, multi-agent systems and economics. I enjoy both theoretical and applied problems. Examples of my past work include simple and optimal auctions, dynamic ad auctions (published in Econometrica and fielded in Google ads), water right market design (fielded in Gansu province, China) as well as reinforcement mechanism design (fielded in Baidu advertising and Taobao search). During PhD, I wrote computer programs to automatically discover theorems in game theory. Two theorems discovered are reported in a top game theoretical journal and the methodology invented has now become a standard technique in social choice theory. I started doing AI and multi-agent systems research back in 2003 when I was a member of the world champion robot soccer team WrightEagle.
