Biography

Reader/Associate Professor in Primate Behaviour and Conservation
Programme manager BSc Animal Behaviour

I am a behavioural ecologist interested in primate social evolution, particularly in regard to sexual selection. I have been working on wild macaques, mostly in Indonesia, for more than 20 years. Apart from my education in animal behaviour, I also received extensive training in field endocrinology during my post-graduate studies. Most of my research so far has focused on the underlying causes for the huge variation in male reproductive skew that we find in multi-male primate groups. More recently, my interest has also turned to primate and other wildlife conservation, and physiological adaptations to (changing) environments.
