My research focuses on the evolutionary and psychological mechanisms underlying human sociality, adopting interdisciplinary approaches at the intersection of evolutionary anthropology, behavioral ecology, experimental psychology and behavioral economics.
My current main research project explores human behavioral immunity, a facet of our sociality linked to the infectious risk imposed by group living, favoring pathogen transmission through increased physical proximity to infected individuals. The aim is to better understand our behavioral immune system, by examining whether humans, like other social species, are able to detect sick conspecifics through phenotypic cues such as facial features or body odors, and whether the perception of these signals induces avoidance behaviors and influences interpersonal decision-making. This research project is being carried out in close collaboration with Mats J. Olsson, Julie Lasselin and Mats Lekander of the Karolinska Institutet in Stockholm, Sweden.
My previous research has focused on cooperation, addressing topics such as the influence of sexual selection on the evolution of cooperation, the existence of phenotypic cues to cooperation, and the role of hormones in cooperative behavior. I have also extended the scope of my research to interspecific comparisons, testing the influence of the propensity to cooperate on mate choice in two other social species, the gleaner mouse(Mus spicilegus) and social weavers(Philetairus socius).
