I am an Associate Researcher at GESIS – Leibniz Institute for the Social Sciences in Cologne. I was previously a Postdoc at the Amsterdam School of Communication Research (University of Amsterdam) with Magdalena Wojcieszak and gained my PhD from the European University Institute (supervisitor Diego Gambetta), visiting the Hertie School Data Science Lab in Berlin (advisor Simon Munzert) and the psychology department of New York University (advisor John Jost). Before that, I studied at the University of Oxford, the University of Bayreuth and Université Paris I Panthéon-Sorbonne. In-between, I worked for the tech startup Opinary and as a freelance write for various outlets such as the Economist.

For my research in computational social science with an interest in misinformation, trust, polarization, media effects and negative campaigning, I use experimental methods, surveys, digital traces and social media data. Recent work has been published in journals such as the Proceedings of the National Academy of Sciences (PNAS), Political Communication and the Journal of Experimental Political Science.
