I am a professor of economics at the University of Cologne and member of the DFG Excellence Cluster ECONtribute of the Universities of Cologne and Bonn. I am the Head of the newly founded Department of Economics and a Director at the FiFo Institute for Public Economics at the University of Cologne. I am a Research Fellow at RF Berlin, CEPR, CESifo, and IZA, and a Research Associate at ZEW.

My research is on the intersection of Public, Labor, and Urban Economics. I use large datasets and exploit quasi-experimental variation to quantify how economic policy affects market outcomes. I am interested in what these behavioral responses imply for the efficiency of economic policies and how they shape inequality. In 2021, I was awarded an ERC starting grant for the project "Housing, Inequality and Public Policies (HIPPO)".

My work has been published in the American Economic Review, Econometrica, the American Economic Journal: Economic Policy, and the Journal of the European Economic Association, among others.
