About me

I am now a postdoctoral researcher in Network Communications and Economics Lab led by Prof. Jianwei Huang, at Department of Information Engineering, The Chinese University of Hong Kong.

I received my PhD degree from IIIS, Tsinghua University in 2018 (supervised by Prof. Andrew Chi-Chih Yao and Prof. Longbo Huang), and my B.S. degree in School of Physics,Peking University in 2013.


I focus on modeling and analysis of network economics, in particular, problems related to pricing, competition, matching and resource allocation in the platform-based sharing economy, using game theory, optimization and learning techniques. My broader research goal is to analyze and optimize social systems consist of interest-driven agents, through the lens of social welfare, revenue, quality of service, etc. I am most excited about research that both provides deep insights to reality and constructs practical algorithmic solutions with performance guarantees.
