Stacy Rosenbaum is a National Science Foundation postdoctoral fellow at the University of Chicago’s Institute for Mind and Biology. She studies the origins and consequences of social behavior in humans and other primates. Her research subjects have included tiny South American marmosets and tamarins, lemurs in Madagascar, and humans in Namibia, but the majority of her work focuses on wild mountain gorillas in Volcanoes National Park, Rwanda. Her current studies explore the often-puzzling relationship between hormones and social bonds in this close human relative. While her favorite activity is following wet gorillas up muddy volcanoes in the rain, Stacy also enjoys developing novel science education projects designed to bring ‘real-world’ science to children in classrooms.
