World-Class Research, Quality Patient Care and a Leading Medical School

The ultimate goal of the UMass Diabetes Center of Excellence is a world without diabetes. Led by a pair of globally renowned diabetes experts in David Harlan, MD and Dale Greiner, PhD, our strategic plan and impressive collaborations places us among top diabetes research and patient care institutions in the world.

Innovative Diabetes Research

What sets our research team apart is that we study human tissues and cells, to reconstruct diabetes in living immune systems, using our unique “humanized” mice. Our internationally respected basic research scientists collaborate to investigate the root causes of diabetes, and apply that knowledge to develop therapies to improve the quality of life for people living with the disease. Our clinical research drives our therapies, providing the best available treatment, to improve the lives of all people living with diabetes.

Comprehensive Diabetes Patient Care

The DCOE care team is continuously improving our individualized patient-centered approach. Recognizing that the individual with diabetes is the most important member of the team, we work with them to provide the most up to date and effective treatments and diabetes education. 


UMass Medical School ranks among the top 10 percent nationwide in primary care according to the annual U.S. News & World Report rankings of the best graduate schools in the country. The report also ranks us as one of the top research institutions. We're preparing the next generation of diabetes experts to responsibly and effectively treat the disease and conduct research to investigate the causes of diabetes. Our work remains at the forefront of innovative educational initiatives as we train physicians, nurse practitioners, nurses, dieticians and certified diabetes educators.
