I am a computational social scientist with an interdisciplinary background in computer science, social psychology, and behavioral science. My research looks at political polarization and the politicization process in online social networks and social news sites, with a particular focus on how this is associated with (mis)information flows. Much of my work draws from classical group psychology theories such as Social Identity Theory, Relative Deprivation Theory, and Extended Contact Hypothesis. I use a variety of design and analytical tools including but not limited to natural language processing, social network analysis, and experimental or quasi-experimental methods (RCTs, regression discontinuity, etc.)
