Dr. Teresa H. Horton received her Bachelor of Science in Zoology from the University of Washington and her PhD in Biology (Ecology, Evolutionary, and Organismal Biology) from the University of Utah. She completed postdoctoral fellowships in reproductive endocrinology (Northwestern University) and comparative endocrinology (University of Delaware). As a human biologist, she combines the principles of biological anthropology, ecology, evolution, psychology, and physiology to investigate the mechanisms by which environmental conditions alter physiology and mental health. Her early research on rodents documented that the transfer of environmental information in utero from mother to fetus had long-term effects on development. She currently is an Associate Professor of Research in the Department of Anthropology, Northwestern University, where she is part of the E2HD, Evolutionary and Ecological Approaches to Health and Development, research program. As increasing scientific evidence supports the hypothesis that disconnection from nature has negative consequences both to the environment and to human health, her research tests the hypothesis that spending time in nature improves health and well-being and investigates the mechanisms that underlie those effects.
