Professor Sauther’s major focus of research is to better understand how both immediate and long-term environmental factors interact with inter-individual variation to affect primate behavior and biology. In essence, she is very interested in how primates “negotiate” living within a variety of environments. Her current research focuses on understanding how environmental stressors such as anthropogenic-induced factors and climate impact both the biology and behavior of wild primates. Her research combines both field work and collaborative laboratory work with geneticists, research veterinarians and others to assess biological markers of ecological stress that includes biometrics, genetics, physiological and health measures.
