Dr. Pollak is a graduate of Princeton University and New York University’s School of Medicine. He did clinical training in Internal Medicine at Columbia-Presbyterian Medical Center, completed his nephrology fellowship at the Brigham and Women’s Hospital and his postdoctoral research training in the Department of Genetics at Harvard Medical School in the laboratory of Jon and Christine Seidman.
Dr. Pollak is a clinical scientist recognized for his studies in the genetic basis of kidney disease. He is known for his contributions to understanding the molecular and genetic basis of diseases of human glomerular function and in understanding the genetic basis the high rate of kidney disease in individuals of recent African descent. Dr. Pollak’s studies have garnered him considerable international stature as a renal molecular geneticist. He has been continuously funded through the NIH since 1992.
His recent notable accomplishments include being elected member to the National Academy of Sciences (2014), selected as the recipient of the American Society of Nephrology, Homer W. Smith Award (2017), and was named Awarded Medical Honoree, from NephCure Kidney International (2020).
Dr. Pollak’s laboratory in interested in the molecular genetic basis of human kidney disease, with a particular focus on diseases of the glomerulus. His laboratory uses a combination of methods, including human genetics, mouse genetics, cell biology, and biochemical tools to understand the connection between phenotype and genotype and to understand glomerular physiology. He and his colleagues have shown that variants in the APOL1 gene both lead to increased rates of kidney disease in people of recent African ancestry, as well as resistance to certain forms of trypanosomal infection. He and his colleagues continue to study the genetics and biology of APOL1-associated kidney disease, a major public health problem in the US. His laboratory hosts bright trainees in nephrology and genetics from BWH, BIDMC, Children's Hospital, as well as outside institutions.

Associate Professor of Medicine
Chief, Kidney and Hypertension Section, Joslin Diabetes Center
Robert C. Stanton, MD, did his undergraduate studies at Harvard College, Medical School at Drexel University, Internal Medicine Residency and Chief Residency at Oregon Health Sciences University, and Nephrology Fellowship at Brigham and Women’s Hospital. Dr. Stanton also did postdoctoral fellowship work with Professor Lewis Cantley at the Tufts University Physiology Department. Dr. Stanton has been involved with research, teaching, clinical work, and administration. Dr. Stanton has been the Chief of the Kidney and Hypertension Section since 1995 and is an Associate Professor of Medicine at Harvard Medical School. He has served on multiple committees at Joslin Diabetes Center and Harvard Medical School including being the current Chair of the Institutional Review Board at Joslin Diabetes Center. From a research perspective, Dr. Stanton’s research has focused on antioxidant and oxidant pathways. Many studies have shown that alterations in these pathways play central roles in the development and progression of many diseases including diabetes, diabetic complications, hypertension, cardiac disease, vascular disease, neurologic diseases, cancer, and many more. Dr. Stanton’s work has focused on an essential enzyme that plays a major role in regulating multiple cellular functions in these antioxidant/oxidant pathways, glucose 6-phosphate dehydrogenase(G6PD) and its principal product, NADPH. His research has determined that G6PD is essential for normal cell growth and in preventing cell death. Work from his lab has shown that changes in this enzyme play a central role in the development of diabetes, diabetic kidney disease, and cardiovascular disease.
From a teaching perspective, Dr. Stanton has been the director of the second-year renal pathophysiology course at Harvard Medical School as well as overseeing the second-year courses at the medical school. Dr. Stanton continues to teach medical students, residents, fellows, and colleagues. From a clinical perspective, Dr. Stanton maintains an active clinic as well as he routinely attends on the consult and dialysis services at the hospital.
Dr. Stanton has given and continues to give many invited lectures in the USA and all over the world. He has written many original articles, review articles, abstracts, chapters, and other educational materials (over 150). He has received three Honorary Professorships from Universities in China and in 2016 he received a major lifetime-achievement teaching award for “Sustained Excellence in Teaching” from Harvard Medical School. He is also routinely listed in the “Best of Boston” editions of Boston Magazine for top nephrologists in Boston.
