skeletal remodeling & behavioral reconstruction in human populations
My research explores how variation in skeletal morphology is related to mechanical forces applied during life. Many experimental and comparative studies show that the skeleton adapts to its mechanical environment, both developmentally and through evolutionary time, by altering its structural organization. Thus, using engineering principles, the preserved morphology of skeletal elements can be used to reconstruct past behavior and other characteristics such as body size and proportions. My work has applied this general approach to a variety of issues in vertebrate biology, focusing in particular on the primate postcranial skeleton: locomotor adaptations among anthropoid primates, the evolution of human bipedal locomotion, reconstruction of stature and body mass, bioarchaeological studies of various recent populations, climatic adaptation, and skeletal growth and aging in both humans and nonhuman primates. My current research is focused on how changes in subsistence strategy and other environmental variables affected skeletal morphology in Holocene European populations; the interaction between locomotion, obstetrics, and body shape among early hominins; and the effects of locomotor transitions during growth on skeletal structure in gorillas and other hominoids.
