My research interests are in the comparative and ecological physiology of fishes and other marine animals. In particular, I’m interested in metabolic, energetic, and cardio-respiratory specializations, and the influence of environment on physiological function. This includes cardiac function and oxygen transport to tissues, metabolic compensations to changes in habitat, such as temperature, salinity, or hypoxia, and bioenergetics of swimming. My aim is to use an integrative approach to determine the types of adaptations and environmental factors that are important in an evolutionary context.
