I am the Irving G. and Eleanor D. Tragen Professor of Law, and Co-Faculty Director, Miller Institute for Global Challenges and the Law at UC Berkeley. My research and teaching interests include international law, comparative law, European Union law, employment law and migration law. To address questions in these fields, my work combines legal analysis with empirical methods. My research appears in leading law reviews and peer-reviewed journals, including the American Journal of International Law, the American Journal of Political Science, the American Political Science Review, the California Law Review, the Chicago Law Review, Comparative Political Studies, the European Sociological Review, and International Organization. I hold a J.D. and Ph.D. from Harvard, and was a junior fellow at the Harvard Society of Fellows.
