Jolle Jolles is a Dutch Behavioural Ecologist who is fascinated by how animals live in groups. His research focuses on the role of consistent individual behavioural differences (animal personalities) in collective behaviour. Jolle recently completed his PhD at the University of Cambridge with Dr. Andrea Manica where he studied the interplay between personality differences and the social context in Three-spined sticklebacks. In March Jolle joined the Couzin lab at the Max Planck Institute for Ornithology in Konstanz. He uses state-of the art individual-based tracking techniques to study how individual differences affect the collective movements, decision-making and group performance of large, dynamic schools of fish, both in the lab and under semi-wild conditions.
