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). During my studies, I worked as a student research assistant for the German Longitudinal Election Study (GLES) at Mannheim University, participated in a research project at Stanford University (US-CA), and worked for two departments at the German Institute for Economic Research (at the Socio-Economic Panel among others).

In January 2016, I joined GESIS. I am a doctoral researcher and worked as a research associate for the EU-funded SERISS project ("Synergies for Europe’s Research Infrastructures in the Social Sciences") until the project came to an end in 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 on the national coordination of the European Social Survey in Germany.
