Johannes Karreth joined the Politics and International Relations Department at Ursinus College in the Fall of 2016. He received his Ph.D. in Political Science from the University of Colorado Boulder with a concentration in international relations, methodology and comparative politics. Prior to coming to Ursinus, he was an assistant professor in the Department of Political Science at the Rockefeller College of Public Affairs and Policy at the University at Albany.
Dr. Karreth specializes in the study of international institutions and examines their role in resolving conflicts in different issue areas. His core research investigates how international institutions such as the World Bank have changed the dynamics of conflict and cooperation in political disputes between and within countries. His book Incentivizing Peace (Oxford University Press, 2018) explores how international institutions can prevent civil wars.
In other research, he studies how international and domestic politics interact, for instance how citizens react to visible aspects of globalization including immigration and changes in political parties’ ideological positions.
Dr. Karreth also studies and teaches social science research methods, especially Bayesian modeling and data visualization. He has taught workshops on quantitative social science at the University of Michigan, University of Essex (UK), University of Copenhagen, and National University of Singapore.
Research with students
Since 2021, Dr. Karreth has been working with students in the Aid and Peace Research Group on analyzing the impact of foreign aid on the negotiation and implementation of peace agreements after civil wars. Current research opportunities for students include projects on:
