Research Interest

I am interested in the evolution of culture in wild apes and the links between culture and cognition from an evolutionary and developmental perspective. During my PhD, I developed the “honey-trap experiment”, a field experiment proposed to several communities of chimpanzees in Uganda. Results showed that chimpanzees would attempt to extract honey from a hole drilled in a log using their cultural knowledge. In particular, the Sonso chimpanzees, who do not use sticks to acquire food in their natural environment, adapted a behaviour normally used to collect water, leaf-sponging, to extract honey from the hole. My subsequent studies and current work aim at understanding how chimpanzee cognition is influenced by their cultural knowledge. Additionally, I am interested in understanding the origin of cultural differences between communities. In great apes, I favour a dynamic model where cultural traits can appear and disappear, depending on the ecological conditions faced by a community as well as on the social structure of this group at a given time, much like our human cultural traits. Recently, I have developed an interest in human studies and aim to replicate and expend the ape studies with human children.
