Summary of Interests:

My research is directed towards investigating why birds live longer than comparably-sized mammals. Birds have higher metabolic rates and higher body temperatures than mammals and are naturally hyperglycemic. These factors should cause an acceleration in the rate of aging, yet this is not the case. Current research in my laboratory involves the determination of the presence and rate of accumulation of certain markers of tissue aging, the effect of various dietary supplements on the rate of tissue aging, and the possible interaction of uric acid as an antioxidant and the resistance of birds to the detrimental effects of their hpyperglycemia. We are also using this methodology to estimate the chronological age of non-domesticated species of birds.

Graduate Research Assistantships are available.
