I am an associate professor at IIIS (Yao class), Tsinghua University
In Tsinghua, I teach game theory (博弈论) as well as economics and computation (计算与经济)
My research focuses on the interdisciplinary topics between AI and Game Theory. I enjoy both theoretical and applied problems. Examples of my past work include simple and optimal auctions, dynamic ad auctions, 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 game theoretical journal and the methodology invented has now become a standard technique in social choice theory.
I have been research consultant for Alibaba, Baidu, DiDi, TouTiao and Microsoft research.
ü Our paper “Non-clairvoyant dynamic mechanism design” is R&R at Econometrica!
ü I gave the Early Career Spotlight Talk at IJCAI-2017 in Melbourne, August 2017
ü Our paper on water market “Stability of generalized two-sided markets with transaction thresholds” has been nominated for best paper and best student paper of AAMAS-2017.
