Since 2025, I am Professor of Game Theory and Evolutionary Dynamics, at IT:U. This is a new university in Linz, Austria, that explicitly focuses on research at the intersection of different fields.

In my group, we explore social behavior (mostly cooperative behavior), using mathematics, computer simulations, and behavioral experiments. For much of our work, we use evolutionary game theory. This framework asks how traits or (strategic) behaviors spread in a population. Some of the questions I have scientifically addressed in the past are: How does inequality affect human behavior? Which kinds of social norms do people use to sustain cooperation? Why do people value modesty? And how do individuals react to environmental change?

Before joining IT:U, I was the group leader of the Max Planck Research Group on the Dynamics of Social Behavior. For more information, please have a look at my publications, and the links below.
