Biographical Information:Richard Lee's research focuses on physiological and ecological adaptations that allow animals to survive at low temperature through the supercooling of body fluids, or tolerance of extensive internal ice formation. He has traveled to the Antarctic and Ellesmere Island in the Arctic to study cold tolerance in terrestrial arthropods. Current major research efforts address both basic and applied questions related to cryobiology, desiccation tolerance, regulation of freezing, and dormancy in overwintering animals.
One line of research supported by the NSF examines the relationship between diapause and cold-hardiness in insects. Recent studies have examined mechanisms of rapid cold-hardening and intracellular freeze tolerance. A second project concerns freezing and desiccation tolerance in the southernmost insect, a wingless fly, on the Antarctic Peninsula. A third area of investigation, in collaboration with Jon P. Costanzo, addresses ecological and physiological aspects of cold hardiness in amphibians and reptiles.
With NSF and the NIH support, field and laboratory studies focus on the adaptive roles of supercooling and freeze tolerance as winter survival strategies, the influence of such responses on physiology, behavior and ecology, and the use of these species as models to provide clues for developing procedures for the cryopreservation of human tissues.
