Fascinated by how animals live and move together in groups, my research is focused on unravelling the role of individual heterogeneity in collective animal behaviour. In my work I try to combine the strong mechanistic approach of Collective Behaviour Research with fundamental concepts from Behavioural Ecology to unravel the link between consistent behavioural variation, the emergence of collective properties and group functioning, and in turn individual fitness and between-group dynamics. I have just build my own research lab, the JollesLab, and am starting to build my own group. If you are interested in working with me drop me an email!
