Research interest
Overall my research aims at testing behavioural responses (swimming activity, feeding behavior, personality traits, cognitive traits) to different biotic and abiotic factors. I used this approach in different contexts with my collaborators specialized in other research fields. In collaboration with evolutionary ecologists, I investigate how ecological and evolutionary factors shape fishes behaviour or how behavioural mechanisms can be potentially involved in shaping biodiversity between and within populations. In the context of aquaculture resources, my objective is to better understand fishes adaptation to farming conditions and associated welfare (e.g. feed trials, farming procedures etc.) using behaviour as a noninvasive tool.
