I am interested in the evolution of social behaviour. My research focuses on how group-living individuals regulate their social relationships, how they manage aggressive conflict within the context of their various relationships, individuals' roles within their social networks and network changes over time. I have explored how individuals maintain their cooperative relationships through reciprocation and interchange of valuable social services. Much of my research has been carried out with non-human primates.

My research has extended to humans to include investigations of mate preferences and sexual advertisement. I am interested in the adaptive nature of human mate preferences and their plasticity and flexibility in today’s societies. This has involved projects examining the influence of feminist attitudes on traditional mate preferences and the manipulation of female clothing in response to increased mate competition.

I currently supervise five PhD students working on a broad range of topics:
Ed Parker – Behavioural ecology of samango monkeys
Harriet Thatcher – Socio-ecology and anthropogenic disturbance in vervet monkeys
Isabelle Szott – Stress & coping strategies in savanna elephants
Simon Stringer – Behaviour and seed dispersal of samango monkeys
James Waterman - Intra- and inter-group relations in Sulawesi crested black macaques
