Andrew Berdahl is a quantitative ecologist who studies movement ecology and collective behavior, including schooling, flocking, herding. More specifically, he explores how group-level behaviors emerge from interactions between individual group members and how the resulting group-level behaviors alter ecological and evolutionary processes. A physicist by training, Andrew combines theoretical models and numerical simulations with empirical, lab- and field-based approaches to establish a deeper understanding of these phenomena.
