I am an associate professor (from July 2017) of comparative politics in the Department of Government at Harvard University, where I am also an affiliated faculty member at the Reischauer Institute of Japanese Studies, the Weatherhead Center for International Affairs, the Minda de Gunzburg Center for European Studies, and the Institute for Quantitative Social Science.

My research focuses on the impact of political institutions, especially electoral systems and candidate selection processes, on aspects of democratic representation and behavior in Japan and Western Europe. I also study Japanese politics more broadly.

My current book project explores the causes and consequences of political dynasties in democracies, with a particular focus on Japan.
