Research:

I am a physical anthropologist with an interest in the development and evolution of brains and behavior. I am especially interested in the value of early social interactions to the honing of the body and brain during sensitive periods of development, and how this may both reflect and contribute to the development and evolution of life in social groups. I am a proponent for the use of phylogenetic comparative methods to draw inferences about the past based on data from extant species, and in this pursuit much of my work concentrates on play and the origins of playfulness in animals. A further area of my current research takes a theoretical and statistical approach to human biological variation, and focuses on the scaling of regions of interest in the human brain.
