I am a research economist at the Halle Institute for Economic Research (IWH) heading the research group "Firm Dynamics and Employment". Since June 2023, I am a member of the Department of Labour Market Processes and Institutions at the Institute for Employment Research in Nürnberg. My teaching portfolio includes causal data science and micro-econometric methods that I am teaching at the Martin-Luther-Universität Halle-Wittenberg and the IWH. I received my PhD from the University of Mannheim. Before joining IWH, I worked as a researcher at ZEW, the Institute for Employment Research (IAB), and the German Council of Economic Experts.
Affiliations:
I am a Junior Research Associate at the Centre for European Economic Research (ZEW) in Mannheim and a Research Affiliate at the New Zealand Work Research Institute (NZWRI) at Auckland University of Technology.
During January to April 2022, I was visiting the University of Chicago as a Visiting Research Scholar.

New Working Paper
We study how connections to German federal parliamentarians affect firm dynamics by constructing a novel dataset to measure connections between politicians and the universe of firms. To identify the causal effect of access to political power, we exploit (i) new appointments to the company leadership team and (ii) discontinuities around the marginal seat of party election lists. Our results reveal that connections lead to reductions in firm exits, gradual increases in employment growth without improvements in productivity. The economic effects are mediated by better credit ratings while access to subsidies or procurement contracts are documented to be of lower importance.
