Background

Dr. Ronadip (Ron) Banerjee is an Assistant Professor in the Division of Endocrinology, Diabetes and Metabolism at Johns Hopkins University School of Medicine.

Dr. Banerjee received his B.S. in Biological Sciences with Honors from Stanford University.  Afterwards, he completed his M.D. and Ph.D. from the University of Pennsylvania School of Medicine in Philadelphia, PA as part of the prestigious MSTP program. His postgraduate medical training included residency in Internal Medicine and a fellowship in Endocrinology, Diabetes and Metabolism at Stanford Hospital and Clinics.  Additionally, as part of the American Board of Internal Medicine Physician-Scientist Research Pathway, Dr. Banerjee completed a postdoctoral fellowship at Stanford University Developmental Biology Department examining hormonal regulation of islet biology.  Previously he was a faculty member at Stanford and University of Alabama School of Medicine before joining Johns Hopkins.

Dr. Banerjee’s laboratory research is focused on hormonal regulation of metabolism in health and disease.  A major focus of the lab is pancreatic islets, including the insulin-producing beta-cells, and how they adapt to physiologic stressors such as pregnancy and dietary adaptation, or are defective in diseases such as gestational diabetes. Current projects are focused on how prolactin receptor regulates expansion of beta-cells in pregnancy, and transcriptional regulatory mechanisms controlling islet cell function in pregnancy and the postpartum.

Dr. Banerjee is board-certified in Endocrinology and Metabolism and maintains an active clinical practice.  His clinical interests include Endocrine Tumors, such as Multiple Endocrine Neoplasia, adrenal tumors and disorders, pancreatic and neuroendocrine tumors, pituitary, thyroid and parathyroid disorders.

Research Summary

Our group is working to expand the understanding of how hormones regulate pancreatic islets in health and disease. 

A major focus of the lab is to define the normal physiologic adaptations of islets, particularly insulin-producing beta-cells, to the metabolic stress of pregnancy.  We hope to use this knowledge to determine how defective adaptation contributes to gestational diabetes (GDM).  

We anticipate that uncovering mechanisms of gestational beta-cell adaptation will help identify novel therapeutic strategies to expand functional beta-cell mass and lead to new treatments for all types of diabetes.
