I am an Assistant Professor in the Department of Applied Economics at Guanghua School of Management, Peking University. Prior to joining Peking, I received a Ph.D. in Economics from Cornell University. My research focuses on empirical industrial organization and applied microeconomics. I am interested in examining the role of social networks in competition in the product market and the welfare effects, digital economy and mobile big data.
