Compared to other group-living species, humans show a remarkable extent of cooperation and readiness to share resources to help each other. At times, however, selfishness trumps pro-sociality, competition is more rewarding than working together, and cooperation is used as a mean to subordinate and hurt others. My research interest broadly revolves around the behavioral and neurobiological underpinnings of these dichotomies – pro-sociality and cooperation on the one side and selfishness and conflict on the other side. To approach these topics, I combine theories and methods from psychology, economics, and neuroscience and design incentivized laboratory interaction experiments.
