Welcome! I am currently a post-doctoral fellow at the Christopher H. Browne Center for International Politics at the University of Pennsylvania. In the spring of 2015, I received my PhD from the University of Texas at Austin, where my dissertation won the 2016 Outstanding Dissertation Award.

My research interests lie at the intersection of international relations and comparative politics. In addition to my work on international hierarchy, my research addresses the interstate sources of civil conflict, the effect of sanctions on international negotiations, and the determinants of leader credibility. You can find more about individual projects, which are organized by topic, under the research tab at the top of this page.

In the past I have been a Graduate Fellow at the Clements Center for History, Strategy, and Statecraft. I also held a research position at the Innovations for Peace and Development lab at UT, where I was the co-lead of the analytics team.
