Research in the Crofoot Lab

The group around Meg Crofoot is interested in the evolution of complex social systems, and specifically, understanding how collective (group) behaviors emerge from interactions among individuals, and how group traits impact individual fitness. They use remote tracking technology in conjunction with field-based experiments and observational methods to explore group movement and decision-making, coordinated territorial defense, and other collective behaviors in primate social groups.
