I am a professor of economics at the University of Cologne and a member of the DFG Excellence Cluster ECONtribute of the Universities of Cologne and Bonn. Until May 2022, I was a professor at the University of Mannheim and Head of the Research Department "Inequality and Public Policy" at the ZEW-Leibniz Centre for European Economic Research.

My research is on the intersection of Public, Labor, and Urban Economics. I am currently studying the effects of local business and property taxes on various labor market outcomes, such as wages, employment, and rents. 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 Journal of the European Economic Association, and the Journal of Public Economics among others. You can find links to my current papers here and my publications here.
