Nathan Tarr is a PhD candidate in the School of Politics and Global Studies at Arizona State University. He specializes in International Relations, Comparative Politics, and Quantitative Methodologies with a specific focus in religious and ethnic conflict, and civil wars. Nathan’s dissertation explores how religion and ethnicity affect the duration of peace through a reconceptualization of how we study identity in a conflict setting. In doing so, he uses an extension of the Cox Proportional Hazard Model to allow for the study of recurrent events. His other ongoing projects examine the role of ethnicity and religion in territorial disputes, and the diverse meanings of Sharia. Nathan’s teaching has included courses on international relations, comparative politics, religion and politics, and research methods. He has been the instructor of the annual Math Camp for incoming PhD students in the School of Politics and Global Studies, has served as the teaching assistant to the department’s graduate methods sequence for four years, and was appointed as a teaching assistant at the University of Michigan’s ICPSR Summer Program.
