About me

I am now a tenure-track assistant Professor in the Institute for Interdisciplinary Information Sciences (IIIS), Tsinghua University.

My research focuses on developing methods and solutions to address challenges in social and computer systems consist of multiple interest-driven individuals, e.g., multi-agent systems. Typically, I model and analyze the system through the lens of game theory, mechanism design, learning and decision making, and algorithms.

My recent studies are mostly on the topics of blockchain systems, collaborative learning, and network economics.

I received my PhD degree from IIIS, Tsinghua University in 2018 (supervised by Prof. Andrew Chi-Chih Yao and Prof. Longbo Huang). I was then a postdoctoral researcher in the Department of Infomation Engineering, The Chinse University of Hong Kong, advised by Prof. Jianwei Huang. Prior to my Ph.D., I received my B.S. degree in School of Physics, Peking University in 2013.

Student recruitment 招生: I am looking for motivated PhD, postdoc, and research assistant/undergraduate intern. Feel free to contact me if you are interested.

Researcher recruitment 研究员岗位(上海)： We also have openings for full time/intern researcher at Shanghai Qi Zhi Institute (SQZ). Feel free to contact me if you are interested.
