Biosketch
David N. Proctor is associate professor of Kinesiology and Physiology and has a joint appointment in the Penn State College of Medicine. He completed his post-doctoral training at the Mayo Clinic and conducts research on the effects of aging and exercise on cardiovascular and muscle function. His current studies are funded by the National Institute on Aging and focus on the regulation of blood flow to exercising muscles in healthy older and younger adults. He teaches courses on exercise, aging, and clinical exercise physiology and was nominated for the George W. Atherton award for excellence in undergraduate teaching in 2004. Dr. Proctor’s graduate students have been supported through a variety of sources including Kinesiology teaching assistantships, the University Fellowship program, the American College of Sports Medicine Foundation and NIH training grants in the Gerontology and Physiology programs. Dr. Proctor is a fellow of the American College of Sports Medicine (ACSM), an ACSM certified exercise specialist, a member of the American Physiological Society, and a member of the American Heart Association. He has served on the editorial board of The Journal of Applied Physiology since 1999 and was nominated for the 2006 Walter B. Cannon award from the American Physiological Society.
