Postdoctoral Scholar

Katie Sayre is a postdoctoral fellow in the Department of Anthropology at the University of California, Santa Barbara. Her work draws on theory and methodology from multiple disciplines, including anthropology, gerontology, public health, and demography. Her work explores how human lifestyles and biology interact over the life course and impact health during older adulthood, particularly in non-Western populations. She has previously examined the relationship between physical activity patterns and physical function during aging in groups of pastoralists and foragers in East Africa. Now, she works with the Tsimané Health and Life History Project, and focuses on how social relationships and communities impact both physical and cognitive health outcomes for older Tsimané women and men in Bolivia. She earned her BA in Anthropology and French at the University of Texas at Austin, her MS in Anthropology at the University of Arizona, and her PhD in Integrative and Evolutionary Biology from the University of Southern California.
