Hi, I'm Georg!

I‘m a first year PhD student at the Chair for Data Science in the Economic and Social Sciences at University of Mannheim under the supervision of Markus Strohmaier. I previously obtained a M.Sc. (with distinction) in Computational Social Systems from RWTH Aachen University. I am passionate about computational social science, natural language processing, and fairness in machine learning. Currently, I‘m thinking about how to use large language models in survey research.
