My research integrates biological and psychological approaches to examine the evolutionary origins of human cognition. I study the cognitive abilities that primates use to solve problems, with a particular focus on humans and other apes. In addition, I investigate why some species solve problems differently from others by integrating cognitive data with information on animals' wild socioecology. By linking studies of mechanism with hypotheses about function, such research can illuminate the roots of human's unique cognitive phenotype.

My current research interests include:
  • Decision-making and executive functioning in apes, monkeys, and humans
  • Spatial memory and foraging skills in apes and lemurs
  • Individual variation in cognitive skills
