Research Interests

My main research interest is in behavioural ecology of primates. In the past, I have studied reproductive strategies and socioendocrinology of wild chacma baboons and economic behaviour of captive vervet monkeys. Recently, I have started a new project that integrates behavior with genetics and endocrinology in wild and captive orangutans. One goal is the collection of genetic data from the remaining populations on Sumatra and Borneo. This data is important to explain geographic variation in orangutan behaviour. The other goal is to measure glucocorticoid metabolites in wild and captive orangutans. This will increase our understanding of the physiological responses of primates to changes in their environment. The hormone project will complement the conservation aspects of genetic studies carried out in our research group and will provide important information to identify priority populations for which conservation efforts need to be intensified and to improve housing conditions of captive orang-utans.
