About the Center

The Jean Mayer USDA Human Nutrition Research Center on Aging (HNRCA) at Tufts University, located in Boston, MA, is one of six human nutrition research centers supported by the United States Department of Agriculture (USDA). We are a bench to bedside research center that generates translational scientific results. We are run by a cooperative agreement between the USDA and Tufts University and our center is one of the largest research centers in the world studying nutrition and its relationship to healthy aging and physical activity. 

The HNRCA is the Tufts University resource for training graduate students and postdoctoral fellows in human nutrition and aging research. Many HNRCA scientists are faculty at the Friedman School of Nutrition Science and Policy, School of Medicine, and/or Sackler School of Graduate Biomedical Sciences at Tufts University and/or have appointments at Tufts Medical Center. HNRCA scientists have ongoing collaborations across the four Tufts University campuses and serve on university leadership positions.
