Background

I am a biological anthropologist broadly interested in the evolution of human behavior and the physiological, social and ecological forces that shaped that behavior through time. I am particularly interested in the behavioral shifts that accompanied the origin of the genus Homo nearly two million years ago, and how those shifts enabled our species to thrive across the globe. Studying this important transition from our earlier ancestors' chimpanzee-like form and lifeways to that of our own lineage is critical to understanding how we as a species and genus are unique, what drove our evolution and why we are the way we are today. 

To answer these questions, I use both experimental laboratory and field-based methods to study how major shifts in anatomy may allow or reflect changes in crucial behaviors. By studying both modern humans and living apes, I am able to understand how anatomical changes found in the fossil record affect the performance of evolutionarily important behaviors. I then use that information to interpret the course of our own behavior evolution.

My current laboratory research studies the biomechanical and performance underpinnings of important behaviors in human evolution, such as throwing, tool making, spear use, and climbing. I am also actively conducting fieldwork in the Turkana region of northwestern Kenya. My ongoing field research includes the description of new hominin remains, examining hominin social organization and land use using 1.5 million year old fossil footprints and studies of throwing and hunting in the Daasanach people.
