Welcome to my website! I am a political scientist and associate professor in the Department of Politics and International Relations at Ursinus College just outside of Philadelphia. I received my Ph.D. in Political Science from the University of Colorado Boulder.

I study the impact of international organizations and processes on politics, focusing mainly on how disputes evolve in different international institutional environments. My research in progress examines the following questions:
  1. When can international organizations use their economic leverage to mitigate interstate disputes?
  2. How can international organizations contribute to preventing and settling civil wars?
  3. How do local and historical context condition voters' responses to partisan realignment and demographic changes in Western democracies?

My published work is available for download here and on Google Scholar. Replication data is located at my Dataverse.

On my teaching page, you can find class materials for the courses I am currently teaching or have taught at Ursinus College, my courses on introductory and advanced quantitative research methods at the ICPSR Summer Program at the University of Michigan and the Essex Summer School, materials from other computing workshops I have taught, and information on teaching awards and evaluations.

Some code for computing functions and examples is located on my GitHub site.

From 2014 to 2016, I was an assistant professor of political science at the Rockefeller College of Public Affairs and Policy at the University at Albany.
