Jochen Reiser, MD, PhD, is chairman of the Department of Internal Medicine at Rush University Medical Center and the Ralph C. Brown, MD, professor of internal medicine at Rush University.
Before joining Rush on Sept. 1, 2012, Reiser was the Peggy and Harold Katz Family professor of medicine, anatomy and cell biology at the University of Miami Leonard M. Miller School of Medicine. He also was the vice chairman for research in the Department of Medicine, chief of the division of nephrology and hypertension and the founding director of the Peggy and Harold Katz Family Drug Discovery Center. He also served as interim chairman of medicine for Miami.
Reiser led a team of international researchers and scientists in discovering the first circulating factor known to start the process leading to focal segmental glomerulosclerosis. They found that a soluble form of the urokinase plasminogen activator receptor (suPAR) is a circulating blood factor that can trigger glomerular kidney disease. Because of Reiser’s discovery, the disease is better understood, and researchers can now work toward developing targeted treatments to prevent what suPAR does to the kidney.
Reiser has authored more than 70 medical and scientific articles. He holds 10 patents and also serves on the editorial board of a number of leading medical journals. Reiser has led international research in molecular mechanisms of glomerular kidney disease. Reiser currently has three NIH-funded grants in renal disease and biomedical research. He is a member of the American Society for Clinical Investigation and was most recently also elected to the American Clinical and Climatological Society.
Reiser earned his medical degree and PhD (summa cum laude) at the Ruprecht Karls University of Heidelberg, Germany, and served his residency in internal medicine at the Albert Einstein College of Medicine in New York. He completed his fellowship in nephrology at Massachusetts General Hospital and Brigham and Women’s Hospital at Harvard Medical School in Boston. Before going to Miami, Reiser was an assistant professor at Harvard Medical School and the founding director of the program in glomerular disease at the Massachusetts General Hospital.
