I am a social scientist interested in social networks, mathematical sociology, and computational social science. I study social influence in the political, economic, and school contexts. My research aims to understand various substantive topics including political polarization, product diffusion, friendship segregation, and intergroup relations. Methodologically, I use agent-based modeling, field experiments, and longitudinal network analysis. Previously I was a Postdoctoral Research Associate at Northeastern University's Network Science Institute and D'Amore-McKim School of Business, working in the Collective Social Systems lab. Here's my CV and my profile page at CUHK's sociology department.
