I am a Professor of Economics in the Adenauer School of Government at the University of Cologne, a Professor in the Department of Economics at Northwestern University (on leave), and a Researcher at GRAPE. I work on Mechanism and Information Design, combining research in pure theory with more applied interests in Inequality-aware Market Design and Financial Over-the-Counter Markets.
