Profile Introduction

I am 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. I 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.
