PhD Candidate  ·  Department of Political Science  ·  Washington University in St. Louis

Welcome! I am a PhD candidate in the Political Science department at Washington University in St. Louis. I'm a formal theorist working in two areas. The first is the political economy of attention and signaling structures that shape information and learning. This work models how political actors can strategically use the way they communicate to influence what people learn and what that means for public welfare and accountability. The aim is twofold: to deepen our understanding of how the contours of political communication shape accountability, institutional trust, and capacity, and to produce clear, testable predictions about these relationships.

The second is social choice theory, where I work on foundational open questions in computational and probabilistic social choice, reconceptualizing these problems and formally verifying results in Lean 4.

Before grad school, I received my BA in Political Science and Economics from the University of Illinois at Urbana-Champaign.

I am on the job market in the 2026–2027 academic year.
