David Friedman graduated from Harvard College and received his medical degree from the Yale School of Medicine. He completed internal medicine residency and renal fellowship at BIDMC. He joined the CVBR in 2008. He is currently an Assistant Professor of Medicine at Harvard Medical School and an attending physician (nephrology) at BIDMC.

Research Interests: Renovascular Disease


Basic Research - My laboratory studies 1) genetic causes of chronic kidney disease; 2) the microvasculature in kidney disease; 3) diabetic nephropathy; and 4) the role of innate immunity and evolution in susceptibility to chronic kidney disease. We use human genetic studies combined with mouse models and molecular biology to understand these disease processes. One major project focuses on the role of APOL1 and the APOL gene family in causing kidney disease in African Americans. Our second focus is on genetic susceptibility to Mesoamerican Nephropathy, an unexplained epidemic of kidney disease in Nicaragua, El Salvador, and other countries in Central America.
