Alexander Ehlert is a PostDoc at the Chair of Social Theory and Quantitative Methods. He studied Economics, Mathematics, and Statistics at the University of Constance, KEDGE Business School Marseille, and the Christian-Albrechts University of Kiel. His main research interests focus on situations in which personal and collective interests are at odds and ways to resolve them, the development and evolution of cooperation and social norms using behavioral experiments, social network analysis, and other quantitative research methods. Hereby, he is particularly interested in the interplay between individual behavior, social norms, and structural contexts shaping outcomes. Student theses should have a solid empirical focus and show how scientific findings can be used to improve people's lives.

Since 2024, he is also the representative of the junior and mid level researchers at the Department of Sociology.
