My primary research interest is in the evolution of language. In particular, I am interested in vocal communication in chimpanzees, one of our closest living relatives. I am currently conducting a PhD within the Evolution of Brain Connectivity project under the supervision of Dr. Roman Wittig and Dr. Cathy Crockford. I am studying the vocal repertoire, its complexity and its ontogeny in wild chimpanzees (Pan troglodytes verus), at the Taï National Park, Côte d’Ivoire.
