I am a Reader (Associate Professor) in the Department of Government, University of Essex. I am an associate editor for the British Journal of Political Science. My research centers around democratic institutions, representation, and data science.
In Comparative Politics, I focus on representation and political institutions that enable representation. One fundamental question is the emergence and origin of institutions. How do polities introduce democratic political institutions? Past work has looked at historical changes of the electoral system and the introduction of direct democratic institutions.
Within data science, I have been working on survey methodology and on ways to use non-probability based samples. I am currently trying to leverage approaches from the machine learning literature 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.
