I studied political science and economics at Mannheim University (receiving my BA in 2013) and at the Free University of Berlin (receiving my master's degree in 2015). 

In January 2016, I joined GESIS. I started as a doctoral researcher and worked for the EU-funded SERISS project ("Synergies for Europe’s Research Infrastructures in the Social Sciences") until July 2019. Between August 2018 and January 2021, I worked for the Core Scientific Team of the European Social Survey (ESS), mainly in the areas of fieldwork (preparation and monitoring), quality assessment, and support for a number of participating countries.

Since January 2021, I work as a Postdoc on the national coordination of the European Social Survey in Germany.
