Biographical Information

As a primatologist and conservation biologist, she has studied 12 monkey species on three continents. She has lived and worked internationally for over five years, including teaching environmental education with Peace Corps Paraguay, studying white-faced capuchins in Costa Rica, teaching Peruvian college students tropical ecology and conservation in the Amazon, and studying seven primate species in the rainforest of Indonesian Borneo. Katie received an M.A. and Ph.D. in Biological Anthropology from the University of California-Davis and a B.S. in Biology and Psychology from the University of Wisconsin-Madison. She uses behavior, ecology, and evolution to help understand how primates (monkeys, apes, and lemurs) adapt to changes in their environments and how we can use the scientific understanding of species to assist in their conservation. She engages the Oxford, Ohio community in conversations about climate change through art and inquiry-based science lesson plans. She also supports K12 teacher professional development programs that connect students and teachers to local and global conservation issues and increase the use of inquiry in science classrooms.
