I am a Professor and Director of Undergraduate Studies in the Department of Political Science at Pennsylvania State University. I received my Ph.D. in 2004 from the Department of Politics at New York University. Prior to this, I received an M.A. in French Studies from the Institute of French Studies at New York University and an M.Phil. in European Politics and Society from Oxford University. I have also taught at Florida State University, the University of Iowa, and the University of Essex.

My research focuses on political representation. In addition to articles in a variety of journals, I have also published two books, Principles of Comparative Politics and Foundations in Comparative Politics. I am currently working on four research projects. The first focuses on the use of multiplicative interaction models, the second examines different aspects of populist politics, the third looks at negative campaigning in a multi-party context, and the fourth investigates women’s representation. I am currently one of the team leaders on an international project looking at Populism and the Future of Democracy. Previously, I have been a member of the executive board for the Making Electoral Democracy Work project led by André Blais at the University of Montreal and the advisory board for the Electoral Integrity Project led by Pippa Norris at Harvard University. In addition to being the chair of the American Political Science Association’s Section on Representation and Electoral Systems (2011-2013),  I have been the co-editor of the Comparative Politics Newsletter (2015-2018) and have served on the editorial boards for the American Journal of Political Science, Comparative Political Studies, and the Journal of Politics. My research has been funded by Canada’s Social Sciences and Humanities Research Council and the United Kingdom’s Economic and Social Research Council.
