Lawrence B. Holzman, M.D.

Chief, Renal Electrolyte and Hypertension Division Professor of Medicine, Perelman School of Medicine, University of Pennsylvania


Dr. Lawrence B. Holzman is an NIH-funded laboratory researcher, well recognized for his investigations of mechanisms of cell signaling and podocyte biology. His work has contributed importantly to understanding the mechanisms that govern podocyte cytoskeletal architecture, and his research has led to multiple discoveries. Dr. Holzman is affiliated with numerous professional organizational fellowships, including the American Society of Nephrologists, the American Heart Association Kidney Council, the American Association for the Advancement of Science, and the National Kidney Foundation Science Committee.

Dr. Holzman received his M.D. training from the New Jersey Medical School, completed a residency at The Hospital of the Medical College of Pennsylvania, and completed a fellowship in nephrology at the University of Michigan. Dr. Holzman has served as a research mentor to several fellows who have gone on to achieve academic positions in the United States and Germany.
