Overview


I am a postdoc at the Düsseldorf Institute for Competition Economics. My research concerns theoretical and experimental studies of human decision-making in strategic environments. I also teach lectures and tutorials on game theory and microeconomic theory at the Master and Ph.D. level.

Game theory

Games in continuous time with coupled populations


Evolutionary game theory makes an important distinction as to whether players interact within a single population or between two or more disjunct populations. Together with Volker Benndorf and Hans-Theo Normann, I explore the synergy of both structures in two papers. We analyze its implications for equilibrium selection combining theory and novel experiments in continuous time.
Mathematical psychology

Interactions between preferences and beliefs in decision-making


The explicit formation of beliefs can affect choice-making patterns, and vice versa. Experimental data reveal violations of the sure thing principle and several other behavioral traits like the so-called consensus effect. In a recent paper, Jacob Denolf, Haeike Josephy, Albert Barque-Duran and I propose a model for these interactions within a general framework of measurement theory and non-classical probabilities.

to rationalize, to explain, and to master it.
