I am an Assistant Professor in the Department of Political Science at the University of Zürich. My research centers around democratic institutions and data science.
Within data science, I have been working on survey methodology and on ways to use non-probability based samples. I am currently leveraging approaches from machine learning to improve MrP (multilevel regression with post-stratification) models. Together with Fabio Wasserfallen, I run the largest online poll in Switzerland and survey voters up to fourteen times a year.
