The many faces of GESIS
Vita
Björn Rohr completed his bachelor's degree in integrative social sciences at the Technical University of Kaiserslautern in 2018. He specialized in sociology. In his master's degree (graduating in 2021) at the same university and in the program of the same name, his focus was also on sociology and quantitative social science.Since September 2021, he has been working at GESIS as a research assistant in the Survey Operations (SDM) team. There, he conducts research on the application of non-probabilistic surveys for the social sciences and on their data quality in comparison to probabilistic surveys.
