Academic Career
Johanna is a PhD candidate at the Graduate School of Economics and Social Sciences. Since August 2021, she works in a project on new data sources in the field of migration and integration research. Johanna holds a Master’s degree in Sociology from the Otto-Friedrich-Universität Bamberg as well as a Master’s degree in Sociology and Social Research from the University of Trento (Italy). In her master thesis, she applied different multilevel approaches using several waves of the European Social Survey as well as data from the European Commission to examine the impact of the current technological change on the effect of having a migration background on different labor market outcomes across Europe. During her studies, she worked as a student research assistant at the Leibniz-Institute for Educational Trajectories (LIfBi) in Bamberg and as an intern at the Department of Sociology and Social Research at the University of Trento. After completing her studies, she worked as a research assistant in the project ‚Refugees in the German Educational System‘ at the LIfBi where she was mainly occupied with data validation.
