Dr. McDonald is a nutrition professor and an authority on the biology of aging. Dr. McDonald believes that in humans and other animals, aging is a rather predictable process but one that is not necessarily typified by deterioration. Lifestyle has a greater impact on the body than does the aging process. In an undergraduate course on the biology of aging, he discusses the aging process from conception to death and explains how various interventions, including diet and exercise, may modify the aging process. His research focuses primarily on the interactions between nutrition and aging.
