I am an Associate Professor in the Department of Political Science at the University of Zürich. I am also the lead editor of the British Journal of Political Science. My research centers around democratic institutions, representation, and data science.

In Comparative Politics, my research delves into the study of political institutions and their role in representation. I investigate the introduction of democratic political institutions, their interaction with the broader representative system, historical changes in electoral systems, and the implementation of direct democratic institutions and their impact on policy alignment. Presently, my research is centered on political participation, with a specific emphasis on the engagement of young voters.

Within data science, I have been working on survey methodology and on ways to use non-probability based samples. Past research has provided alternative MrP (multilevel regression with post-stratification) models that have relaxed data requirements (MrsP). In addition, I have also explored how one can leverage machine learning algorithms to improve small-area estimation (autoMrP).  Together with Fabio Wasserfallen, I run the largest online poll in Switzerland and survey voters up to fourteen times a year.
