I am interested in the evolution of sociality and cooperation in human and non-human primates, as well as in social vertebrates more generally. My research takes a multifaceted approach, which includes behavioral observations of primates in the wild, the analysis of long-term demographic data, and mathematical modeling.
My current project aims at developing a general mathematical theory of social evolution in human and non-human primates. My research combines the verbal reasoning behind the ‘Socioecological Model’ of primate social organization with theoretical approaches developed in the broader field of evolutionary biology, focusing particularly on cooperation and competition among kin. The goal of my project is to develop a theoretical framework that derives clear, testable predictions, and that links primate socioecology with the broader field of behavioural ecology.
