I am a behavioural ecologist. More specifically, my research interests lie in the fields of animal behaviour, decision rules, 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), 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.

Optimal foraging in a changing world: old questions, new perspectives

Marginal value theorem (MVT) is an archetypal model discussed in every behavioural ecology textbook. Its popularity is largely explained but the fact that it is possible to solve it graphically (at least in its simplest form) with the minimal amount of equations, which is a sensible strategy for an introductory course in behavioural ecology [1]. Apart from this heuristic value, one may be tempted to disregard it as a naive toy model. After a burst of interest in the 70's and the 80's, the once v...
