After having completed my undergraduate studies in Philosophy and Social Sciences at the University of Lille (2008), and a master's degree in Cognitive Science at the Ecole des Hautes en Sciences Sociales (2010), I undertook a PhD at the Université Pierre et Marie Curie (2013). Additionally, I was a visiting student at the Institute of Cognitive and Evolutionary Anthropology at the University of Oxford (2011), and I also collected data on semi-wild chimpanzees at the Chimfunshi Wildlife Orphanage (Zambia) as part of the Primate Field Research Project (August 2012).

By February 2013, I was a visiting post-doctoral researcher of the Centre of Comparative and Evolutionary Psychology in Portsmouth. I investigated the vocal behaviour of infant chimpanzees. Field work was conducted in the Sonso community of the Budongo Forest and supervised by Prof Klaus Zuberbühler (University of Neuchatel - University of St Andrews) and Dr Marina Davila-Ross (University of Portsmouth).


My broad interest is in (human and non-human) primate social behaviour. More recently, I have been interested in the topic of the evolution of communication, notably emotional communication.
