About me

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

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.

I am looking for motivated PhD, postdoc, and undergrad students. Feel free to contact me if you are interested.


My research focuses on developing methods and solutions to address challenges in multi-agent systems consist of interest-driven individuals. Specifically, my recent studies are mostly on the topics of online platforms and blockchain systems. I model and analyze the systems through the lens of mechanism design, mathematics optimization, economics, and algorithms.
