Angèle Lombrey is a PhD student in the department of palaeoanthropology at the University of Tübingen. After completing a 5-year engineering school, she did a Masters in Ecophysiology, Ecology and Ethology at the university of Strasbourg. Her MSc thesis focused on individual variation in the communicative behaviour of captive adult chimpanzees (Pan troglodytes), and constituted a pilot study for her current work. As part of a larger research project aiming to provide insight on the role of plasticity in hominid communication and the evolution of language, the goal of her PhD project is to assess the multimodal communicative behaviour (i.e. including manual and bodily gestures, vocalisations and facial expressions altogether) of adult wild, sanctuary- and zoo-housed chimpanzees, with a focus on joint action contexts, to partition variation into environmental, among-individual, and within-individual sources.
