I am a Ph.D candidate in Political Science at Duke University. My interests lie at the intersection of three lines of research: political behavior, political economy, and big data methods for social sciences. I work from a comparative perspective, with an emphasis on developing and non-democratic countries. In my dissertation Lies to Friends, Truths to Strangers: Anonymity, Preference Falsification, and Opinion Polarization in Authoritarian China, I develop a new theory explaining individual behavior in lying about political preferences online and offline in the social media era and its implications for authoritarian institutions. Using text-as-data methods, I show the behavioral pattern and its implications by analyzing an original dataset of text and networks in a large Chinese social media site.
