Dr. Thometz is a broadly trained physiological ecologist who specializes in marine mammal physiology, ecology, and behavior. She has spent nearly a decade studying the ontogeny of energy demands, development of diving capacities, reproductive energetics, and foraging behavior of southern sea otters. In addition, Dr. Thometz has studied the foraging behavior and physiology of Weddell seals in the Antarctic, the metabolic demands and diving capacities of Hawaiian monk seals, the comparative physiology of sound production muscles in a variety of odontocete species, as well as the physiological requirements and diving capacities of a number of Arctic phocids, including: ringed, bearded, and spotted seals.
