Johannes Karreth is an Assistant Professor in the Department of Politics and International Relations at Ursinus College in Collegeville, Pennsylvania. He studies the impact of international organizations and processes on politics, focusing mainly on how disputes evolve in different international institutional environments. His recent work investigates when international organizations can use their economic leverage to mitigate interstate disputes; the role of international organizations in preventing and settling civil wars; and voters’ responses to partisan realignment and demographic changes in Western democracies.

His research has been published in outlets such as the Journal of Politics, International Interactions, and Comparative Political Studies. His book Incentivizing Peace: How How International Organizations Can Help Prevent Civil Wars in Member Countries (with Jaroslav Tir) was published with Oxford University Press in 2018. Dr. Karreth teaches courses on quantitative research methods in social science, including a workshop on Applied Bayesian Modeling at the ICPSR Summer Program at the University of Michigan. At the undergraduate level, he teaches courses on international political economy, political violence, and other topics in international relations. He is a member of the Digital Liberal Arts working group at Ursinus College, a group of scholars seeking to promote the use of (reproducible) digital methods of scholarship across disciplines among faculty and students.
