I am an American Political Science Association Congressional Fellow, and in 2020 I will start as an Assistant Professor at the University of Michigan.   I specialize in American political institutions, particularly Congress, but also the presidency and bureaucracies.  My research draws on game theory, evolutionary and social psychology, and historical sources to understand how politicians influence one another and the consequences of this activity for the rules and structure of political institutions.  I also develop new quantitative methods for adapting techniques from machine learning for inference.
