I am a professor of economics at the University of Cologne and a Faculty Member of the DFG Excellence Cluster ECONtribute of the Universities of Cologne and Bonn. I am a Director at the FiFo Institute for Public Economics at the University of Cologne, a Research Fellow at CEPR, CESifo, CReAM, 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)". Stay tuned for the first results. 

My work has been published in the American Economic Review, the American Economic Journal: Economic Policy, the Journal of the European Economic Association, and the Journal of Public Economics, among others. Please follow the links to my current papers, publications, or CV.
