Dale L. Greiner, PhD
Dr. Eileen L. Berman and Stanley I. Berman Foundation Chair in Biomedical Research, Professor, Program in Molecular Medicine, Co-Director, Diabetes Center of Excellence at UMass Medical SchoolDr. Greiner is nationally and internationally recognized for pioneering the development and use of mice engrafted with functional human cells and tissues.
Interests: Human immune responses, both how to turn them off for the treatment of type 1 diabetes and autoimmunity and conversely, to use the same pathways to turn the immune response on for the treatment of cancer. We utilize our unique animal models of human immune responses for investigating these approaches to downregulate as well as activate the human immune system.

David M. Harlan, MD
William and Doris Krupp Chair in Diabetes, Professor of Medicine and Co-Director, Diabetes Center of Excellence at UMass Medical SchoolFor more than 30 years, Dr. Harlan has conducted basic and clinical research exploring the pathophysiology underlying diabetes. His accomplishments and expertise are acclaimed worldwide as a diabetes investigator and physician.
Interests: Exploring beta cell biology and the anti-beta cell immune response underlying type 1 diabetes. We've developed innovative techniques to sort human pancreatic islet endocrine cell subsets, including from donors with both type 1 and type 2 diabetes, to determine the transcriptome from those purified cells. We're also working to develop better diabetes care delivery models.

Michael A. Brehm, PhD
Robert and Sandra Glass Term Chair in Diabetes, Associate Professor, Program in Molecular MedicineInterests: Understanding the immune mechanisms that regulate the development of human autoimmune disease. We've developed unique "humanized" mouse models of human immune responses, allowing us to investigate approaches to downregulate as well as activate the human immune system for the treatment of type 1 diabetes as well as potential cancer treatment.

Silvia Corvera, MD
Chair in Diabetes Research, Director, MSTP (MD-PhD) Program, Professor, Program in Molecular MedicineInterests: Understanding the basic physiopathology of type 2 diabetes, specifically the role of adipocytes and adipose tissue physiology in diabetes pathogenesis.
-
Michael P. Czech, PhD
Isadore and Fannie Foxman Chair of Medical Research, Professor, Program in Molecular MedicineInterests: Our laboratory is dedicated to the discovery of molecular mechanisms whereby insulin signaling regulates energy homeostasis. This includes RNAi screens, digital imaging and TIRF microscopy, phenotyping mice with gene knockouts and analysis of human adipose tissues. We hope to translate our findings to the prevention and treatment of type 2 diabetes.
-
Roger J. Davis, PhD, FRS
H. Arthur Smith Chair in Biomedical Research, Chair, Program in Molecular Medicine, Howard Hughes Medical Institute Investigator, Fellow of the Royal Society, Member of the National Academy of ScienceInterests: The molecular mechanism by which inflammation contributes to diabetes, cancer and stroke. Our studies of stress signaling pathways have led to the discovery of new genes that contribute to the development of diabetes and other diseases.
-
David A. Guertin, PhD
Professor, Program in Molecular MedicineInterests: Understanding how insulin resistance develops, especially in obesity and lipodystrophy. Identifying therapeutic strategies to improve how the body processes blood sugar(glucose). Exploring the biochemical mechanisms controlling cell growth and metabolism and their significance to the pathogenesis of metabolic diseases including type 2 diabetes.
-
Sally C. Kent, PhD
The George F. and Sybil H. Fuller Term Chair in Diabetes, Associate Professor, Department of MedicineInterests: Autoimmune response in human type 1 diabetes. In particular, T cell responses to self-proteins. We want to understand how and why these immune cells are attacking the insulin producing beta cells in people with T1D.
-
Jason K. Kim, PhD
Professor, Program in Molecular Medicine, Director, UMass Mouse Metabolic Phenotyping CenterInterests: Our research investigates obesity, diabetes and its complications. The goal of our research is to understand how obesity causes diabetes and to find its cure.
-
Hardy Kornfeld, MD
Professor, Department of MedicineInterests: The impact of diabetes and hyperlipidemia on tuberculosis defense
-
Yunsheng Ma, MD, PhD, MPH
Associate Professor, Department of MedicineInterests: Prevention and treatment of type 2 diabetes, as well as racial/ethnic disparities in the prevalence, incidence, treatment, medical and survival outcomes among diabetic patients.
-
René Maehr, PhD
Glass Charitable Foundation Term Chair in Diabetes, Associate Professor, Program in Molecular MedicineInterests: The molecular pathways that govern thymus organogenesis and function, and to translate this knowledge to stem cell approaches to recapitulate and investigate human immune syndromes associated with this organ, including type 1 diabetes.
-
Louis M. Messina, MD
Johnnie Ray Cox Term Chair in Biomedical Research, Professor and Vice Chair, Department of SurgeryInterests: Investigating new hematopoietic stem cell–based therapeutic approaches to treat type 2 diabetes and other common diseases. Determining the effects of T2D on wound healing and identifying the molecular and cellular mechanisms that could lead to potential therapies.
-
Tiffany Moore Simas, MD, MPH, MEd, FACOG
Chair and Professor, Department of Obstetrics and GynecologyInterests: Understanding the role that adipose tissue plays in gestational diabetes, as well as angiogenic biomarkers and gestational weight gain.
-
John P. Mordes, MD
Professor, Department of MedicineInterests: Basic and clinical research in the area of type 1 diabetes.
-
Jennifer P. Wang, MD
Associate Professor, Department of MedicineInterests: How innate immune responses contribute to autoimmune disease processes, in particular how activation of inflammatory pathways and type I interferon can lead to type 1 diabetes
-
Yong-Xu Wang, PhD
Associate Professor, Program in Molecular MedicineInterests: Brown fat development and browning of white fat. We particularly focus on transcriptional control, epigenetics, non-coding RNAs, and signaling molecules.
