Research Interests

I am interested in the evolution of group-living in primates and other social mammals. Specifically, my research aims at understanding the differential costs and benefits of group-living to individuals of different social ranks and the consequent implications on group stability. Moreover, using a combination of game theoretical modelling and long term demographic data on two species of gregarious lemurs (Eulemur fulvus rufus and Propithecus verreauxi) I also investigate the role of life history in shaping a species’ social organisation.
