Director and Senior Scientist,
Jean Mayer USDA Human Nutrition
Research Center on Aging
Professor of Nutrition and Medicine,
In his role as Director of the Nutrition, Exercise Physiology, and Sarcopenia Laboratory, Dr. Fielding has explored the effects of nutrition, pharmacological, and exercise therapies on changes in skeletal muscle structure and function with advancing age, and has examined the role of nutrition and exercise on muscle performance in older animals and humans.
Dr. Fielding began his research career in the Department of Health Sciences at Boston University, initiating studies that examined the role of skeletal muscle power output on physical function and disability in older adults, as well as parallel studies examining the influence of aging on intracellular signaling events in contracting skeletal muscle. In 2004, Dr. Fielding was recruited to the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University and has since conducted numerous clinical studies of exercise and muscle function in older adults.
Dr. Fielding is an internationally known researcher who studies the underlying mechanisms contributing to the age-associated decline in skeletal muscle mass, the resultant impact on function, and the potential role of exercise, nutrition, and physical activity on attenuating this process. He is an associate editor of The Journals of Gerontology: Medical Sciences, Calcified Tissue International, and The Journal of Musculoskeletal Research. He has also served as a reviewer on numerous NIH study sections and was recently elected to the NIH/CSR College of Reviewers. In 2015, he received the Olof Johnell Science Award from the International Osteoporosis Foundation. Dr. Fielding earned his PhD from Tufts University and an MA in Physical Education with a concentration in Human Bioenergetics from Ball State University.
