What We Do

Our research examines the evolutionary origins of the human mind by comparing how humans and other animals think about the world. We aim to uncover the roots of humans’ unique cognitive phenotype, as well understand what evolutionary processes support the emergence of complex cognitive skills across species more generally.

We approach these problems by integrating theory from evolutionary biology with experimental methods from psychology to probe the mechanisms supporting behavior. Our goal is to link specific cognitive abilities to their biological function, with current projects focused on decision-making, spatial memory, and social cognition. We study several primate populations including apes living in African sanctuaries, semi-free-ranging monkeys and lemurs, and humans.
