Short Bio

After receiving my M.Sc. in Mathematics at the Technical University of Munich, I started my my Ph.D. in the computer science department under the supervision of Martin Bichler. In my research, I investigate learning dynamics in multi-agent systems with application to economic settings such as auctions and contests. In particular, I am interested in the underlying structures that allow simple learning algorithms to reach the equilibrium strategies in these games. In most of my projects I rely on methods from online convex optimization and numerical simulations.
