Roger A. Fielding, Ph.D. is Associate Director of the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University and serves as Director and Senior Scientist of the Nutrition, Exercise Physiology, and Sarcopenia (NEPS) Laboratory. He is also Professor of Nutrition at the Friedman School of Nutrition Science and Policy, Professor of Medicine at Tufts University School of Medicine and the Associate Director of the Boston Claude D. Pepper Older Americans Independence Center. 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, physical activity and other therapies on attenuating this process. He has published over 200 peer-reviewed papers with over 8,000 citations and has conducted numerous cross sectional, longitudinal, and intervention studies examining the role of skeletal muscle power on physical performance in older adults. Dr. Fielding is an associate editor of the Journals of Gerontology: Medical Sciences, Calcified Tissues International, and Musculoskeletal Research. He has also served as a reviewer on numerous NIH study sections and was elected to the NIH/CSR College of Reviewers. In 2015, he received the Olof Johnell Science Award from the International Osteoporosis Foundation.
