I study American political institutions, with a focus on how information and uncertainty influence the behavior of elected officials and candidates. My dissertation research studies how legislators' uncertainty about the future shapes the evolution of legislative rules, with a specific focus on the Senate filibuster. A second line of work considers how informational asymmetries between voters and elites influence candidate behavior. My work applies formal methods to study these questions, as well as a range of empirical and qualitative methods to evaluate the predictions of my models.
I am a PhD Candidate in the Department of Political Science at Stanford University and am on the academic job market in the fall of 2025. I am advised by Professors Avi Acharya (co-chair), Brandice Canes-Wrone (co-chair), Justin Grimmer, and Ken Shotts. Before my time at Stanford, I went to the University of Rochester, where I completed a B.A. in Political Science.
