I am a comparative psychologist specializing in social cognition. Currently I work as an Assistant Professor at the Animal Behaviour and Cognition Group of Utrecht University (NL). My research mainly focuses on the proximate mechanisms underlying animal social relations, with special interest in emotions and (their role in) cooperative and prosocial behaviours. For that I use both observational and experimental approaches. Moreover, to put my studies in an evolutionary perspective, I employ a broad comparative approach, focusing on a variety of primate and bird species.


Currently, I also function as the acting President of the European Federation of Primatology (EFP)
