Research interests

My research focuses on the use of technology by wild chimpanzees and bonobos. Since 2003, I have been studying the chimpanzees at the Seringbara study site in the Nimba Mountains in Guinea, West Africa. Recently, I have included both East African chimpanzees and bonobos in an intra- and inter-species comparison of ape technology. I seek to illuminate the roles of the environment, sociality and cognition in shaping the use of technology by our closest living relatives, in order to understand the processes that drive the origins and evolution of human material culture. Increasing the awareness of our close evolutionary links with the African apes provides us with the tools to promote the conservation of our endangered cousins.
