Joseph O'Mahoney

Joseph O'Mahoney, Ph.D.

Assistant Professor

School of Diplomacy and International Relations


My current research is on the role normative ideas play in how states make peace, and how these ideas change over time.

Joseph O'Mahoney joined the School of Diplomacy and International Relations as an Assistant Professor in 2013. His primary research agenda is in international norm dynamics and the politics of peace settlements. Other research interests include international symbolic sanctions, the termination of interstate wars, and change in international norms and institutions. He is also interested in research design and methodology, in particular issues of the interpretation of data, both qualitative and quantitative.

O'Mahoney teaches classes in international relations theory and research methods. Prior to joining Seton Hall, he taught at Brown University and George Washington University.
