John A. Henderson

I am an Assistant Professor in the Department of Political Science at Yale University. I am also affiliated with the Center for the Study of American Politics, and the Institution for Social and Policy Studies.

I study the consequences of polarization on representation and policymaking in the U.S., as well as the causes of participation and vote choice in congressional and presidential elections. My current research focuses on understanding how and why candidates' communication strategies have evolved over the last fifty years, as politicians compile increasingly partisan and polarized records in Congress. My main methodological interests include improving research design for causal inference, especially through sensitivity analysis, matching, and instrumental variables in the context of imperfectly randomized experiments. I also study machine learning and crowdsourcing approaches to analyze text data.
