Welcome to my website!

I direct the Research area Political Sociology at the Institute for Political Science at the University of Zurich. In 2018/2019 I was an Alexander von Humboldt Alumni Fellow at the Democracy and Democratization unit at the Berlin Social Science Research Center (WZB). 

My research and teaching focuses on comparative political sociology. I have worked on the transformation of cleavages and party systems in Western Europe and on the rise of right-wing populist parties. Currently, much of my research focuses on party system formation in Latin America, both in historical perspective, as well as with a focus on the competitive strategies of contemporary political parties.
