Stacy is a biological anthropologist interested in the evolutionary origins of social behavior. Her dissertation research focused on paternal care and the relationship between wild adult male mountain gorillas and the young animals in their social group. She is an assistant professor in the Department of Anthropology at the University of Michigan, where she studies social behavior and endocrinology in gorillas (in Rwanda), baboons (in Kenya), and humans (in the Philippines).

Stacy is active in science education and outreach. She enjoys teaching children and adults alike about the importance of field science, what we can learn from studying great ape behavior, and how everyone can contribute to conservation of endangered species and habitats.
