Personal Statement

Leonardo R. Arriola studies the challenges associated with representation and governance in multiethnic societies. His research examines inter-ethnic political cooperation, party competition under ethnic polarization, and political violence in divided societies. His award-winning research has been published in outlets such as the American Journal of Political Science, Comparative Political Studies, and Journal of Politics along with books published by Cambridge University Press and Oxford University Press. His work has been funded by grants from the U.S. National Science Foundation (NSF), Research Council of Norway, Carnegie Corporation of New York, U.S. Department of Defense, Harry Frank Guggenheim Foundation, and Evidence in Governance and Politics (EGAP). He is co-editor of Africa Spectrum, an interdisciplinary journal published by the German Institute for Global and Area Studies (GIGA), an associated senior researcher at the Chr. Michelsen Institute (CMI) in Norway, and a board member of the African Studies Association (ASA).

As the first in his family to go to college, Professor Arriola understands the importance of student mentoring and advising. He regularly offers research opportunities for undergraduate students through Berkeley’s Undergraduate Research Apprentice Program (URAP), and he is dedicated to helping graduate students successfully complete the PhD and pursue their professional goals. He is a past recipient of the Carol D. Soc Distinguished Graduate Student Mentoring Award from Berkeley’s Graduate Division and the Graduate Council of the Academic Senate.
