Biological Anthropology

Research Interests:

Interdisciplinary trained applied biological anthropologist with a focus on biocultural, evolutionary, and developmental approaches to human biology, behavior, and health, with a combined 12 years of teaching, research, publishing, and medical field experience. My expertise lies at the intersection of Human Behavioral Ecology, Cultural Evolution, Behavioral Neuroendocrinology, Life History Theory, Childhood Development, and Psychobiology to explain cross-cultural patterns of human variation, health, physiology, sexuality, gender, and behavior.
