I am a tenured associate professor at the Institute for Microeconomics and the Hausdorff Center for Mathematics at the University of Bonn. I am also a research affiliate at the Global Priorities Institute at the University of Oxford. Previously, I was a postdoctoral research scholar at the Economics Departments of Princeton University and Stanford University. I obtained a Ph.D. degree in mathematics from the Technical University of Munich under the supervision of Felix Brandt. My research interests cover various areas of microeconomic theory including social choice theory, decision theory, and game theory.
