About

I am a Postdoc at Northwestern University Institute on Complex Systems (NICO). I work with Brian Uzzi at the Kellogg School of Management. I am interested in computational social science, science of science, and social networks. My research studies the mechanisms involved in the production and dissemination of science and innovation. I earned my PhD from University of Michigan School of Information (UMSI), where I was advised by Daniel M. Romero. I received my bachelor's degree in Information Management from Sun Yat-sen University in China.
