Kristi Lewton is a biological anthropologist and evolutionary anatomist, and is an Assistant Professor at the Keck School of Medicine. Kristi received her bachelor's degree from the University of Washington, her master's and doctoral degrees from the School of Human Evolution and Social Change at Arizona State University, and a postdoctoral preceptorship at Harvard University.

Kristi Lewton's research focuses on the evolution of primate locomotor systems. She studies the anatomy and biomechanics of human and non-human primate hindlimbs to understand the evolution of these structures, integrating both comparative morphometric and experimental approaches. Her current work focuses on identifying adaptations to locomotion in the pelvis; examining patterns of integration, modularity, and evolvability of the pelvic girdle in primates, carnivores, and mice; and investigating the relationship between pelvic anatomy and metabolic cost of locomotion in humans. In addition to museum and laboratory research, Kristi has conducted paleoanthropological fieldwork surveying for hominin fossils in South Africa and Ethiopia.

At the Keck School of Medicine, Kristi teaches human gross anatomy to first and second year medical students.
