Terrie M. Williams, PhD is a comparative ecophysiologist at the University of California- Santa Cruz. She is the Director of the Center for Marine Mammal Research and Conservation at UCSC. For the past 30 years her research has investigated the physiology of large mammalian predators. Specifically, Dr. Williams and students are trying to understand “how animals survive” in a world that is constantly changing. By examining the functional relationships between animals and their environment, these researchers hope to understand the ecological significance of a species and the physiological adaptive changes that may be necessary for its survival. Her publication credits include over 100 scientific articles a recent book, “The Odyssey of KP2” (Penguin Press) detailing her efforts to save the endangered Hawaiian monk seal.
