A lot of our work focusses on the evolutionary origin of proactive prosociality. Across several primate species, including humans, proactive prosociality is particularly high in species with shared infant care (cooperative breeding).
We are also interested in prosocial behavior under naturalistic situations (in the wild), and how it is regulated proximately with regard to the role of the neurohormone oxytocin, to what extent these behaviors are under intentional control, or how it is affected by bystanders.
