I am professor of behavioural ecology in the university of Lyon. My research interests lie in the fields of animal behaviour, decision-making, rationality, mate choice, sexual selection, animal personality, and foraging strategy. So far, I had the opportunity to work on a wide range of species: insects (honeybee, ants, carabids, Tenebrio), amphipod (Gammarux pulex), fish (convict cichlid, round goby), and bird (Zenaida dove). In addition to this experimental work, I indulge myself in theoretical approaches. From a taxonomic viewpoint, my favourite species of models are related to game theory, dynamical systems, and individual based simulations. Finally, I am also interested in statistical methodology.
