I am primarily interested in the study of collective animal behavior. In particular I am looking for the mechanisms that are implied in the production of individual decision, social interactions from which emerge more complex properties at the level of the groups. My research focuses on the collective movements using sheep as a model study. We quantify the decision of sheep either in undisturbed conditions but also when the movement of individuals are experimentally manipulated. The acquisition of precise data on location and behavior allow addressing the question of information transfer. I also work on how social buffering effect may depend upon the number of conspecifics present in sheep and mice. We study the response of stress, behavioural output and emotion when animals face an acute environmental stressor. One main challenge is to link between individual responses and the collective output (social cohesion, collective behavioural states, activity transition). I still collaborate in the study of sexual segregation.
