Research Interests
Professor Warren is broadly interested in understanding how animals respond and adapt to environmental change, particularly in response to variations in temperature and oxygen availability. At the moment, his work is centered around the physiological adaptations of North American pond turtles, which can experience extremes in both cold and oxygen availability while overwintering in the northern portions of their geographic range. His work is especially focused on neurophysiological and cardiovascular function of turtles, and how they can tolerate oxygen deprivation for many months. His group uses a variety of approaches spanning nearly all levels of biological organization, including systemic physiological responses, the physiology of individual neurons and cardiomyocytes, and the expression of genes in specific neuronal cell types.
