Roger Fielding, Ph.D.

Roger A. Fielding, Ph.D., is Senior Scientist and Director of the Nutrition, Exercise Physiology and Sarcopenia Laboratory at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University, where he and his team investigate how diet and physical activity can influence the age-related loss of skeletal muscle mass and function, a condition known as sarcopenia.

His laboratory is one of eight sites nationwide involved in the largest randomized controlled trial on physical activity in older adults. The NIH-funded study will help determine whether exercise can prevent or delay major movement disability in adults ages 70 to 89. Other research focuses include a group of signaling proteins that may be hampering muscle growth with age and the role of declining muscle power in the physical function of older adults.

Dr. Fielding is also Professor of Nutrition at the Gerald J. and Dorothy R. Friedman School of Nutrition Science at Policy at Tufts University and Professor of Medicine at Tufts University School of Medicine.   He is a member of the American Federation for Aging Research National Scientific Advisory Council, associate director of the Boston Claude D. Pepper Older Americans Independence Center, and a member of the International Working Group on Sarcopenia Task Force.
