Welcome! I am an Assistant Professor of Political Science at the University of Oregon (on leave AY 2020). Before arriving to UO, I was a post-doctoral research fellow at the Center for the Study of Democratic Politics at Princeton University (AY 2020) and received my Ph.D. in political science from the University of California, Berkeley.
My research focuses on political parties, Congress, polarization and representation. I have published on these topics in the Journal of Politics and Perspectives on Politics.
My book project uses original archival research, secondary accounts, and under-utilized public opinion data to understand the role of the mass public and racial realignment in shaping today’s party system in the United States. I argue contemporary polarization is rooted in long-standing issue connections between racial attitudes and other policy views among ordinary voters.
