Mary Ann Ottinger is Professor Emeritus at the University of Maryland and the University of Houston, holding a Ph.D. in Behavioral Neuroendocrinology. Her research focuses on neuroendocrine function, comparative biology of aging, and the effects of endocrine-disrupting chemicals. Her studies in Japanese quail revealed conserved mechanisms in age-related endocrine decline and highlighted differences in oxidative damage resistance compared to long-lived birds. Her work in non-human primates explored calorie restriction's effects on aging, while studies in transgenic Alzheimer's disease mouse models showed the benefits of selective estrogen receptor modulators. Recent research integrates One Health, the Exposome, and conservation for a comprehensive environmental health perspective. Dr. Ottinger has received the Sigma Xi Research Award, OECD Fellowship, and Gamma Sigma Delta Research Award, and is a Fellow of the Society for the Study of Reproduction, Poultry Science Association, AAAS, and the Explorers Club.
