About Irving D Weiner

I am a professor of medicine in the University of Florida Division of Nephrology, Hypertension & Renal Transplantation and co-holder of the C. Craig and Audrae Tisher Chair of Nephrology. I am also the chief of the nephrology and hypertension section of the North Florida/South Georgia Veterans Health system. I have an active clinical practice specializing in resistant hypertension and in the management of autosomal dominant polycystic kidney disease. I also see patients with almost every form of kidney or electrolyte disorders. I direct an NIH-, VA- and AHA-funded research program that has resulted in more than 100 peer-reviewed publications, which is in addition to having written more than 30 book chapter and co-authoring one nephrology textbook.

I earned my medical degree from Vanderbilt University in 1984. Then, I went on to complete an internal medicine internship and residency at the University of Texas Health Science Center at San Antonio. I completed nephrology fellowship training at Washington University St. Louis/Barnes-Jewish Hospital in 1990.

I have extensive experience in administrative roles, having previously served as interim clinical chief of the UF Division of Nephrology, Hypertension & Renal Transplantation, director of the nephrology fellowship program at UF, chair-person of the UF Health Shands Hospital pharmacy and therapeutics committee, co-director of the MS2 nephrology course for the UF College of Medicine, member and chair-person of the Department of Veterans Affairs merit review subcommittee for nephrology, standing member of the NIH Kidney Molecular Biology and Genitourinary Development committee, and director of the UF Division of Nephrology, Hypertension & Renal Transplantation outpatient clinic program.

Research Profile

Dr. Weiner’s pre-clinical research interests focus on the molecular mechanisms and the regulation of acid-base hemostasis. This includes studies on ammonia metabolism, including regulation of production and novel mechanisms of transport by specific proteins. Dr. Weiner’s laboratory played a major role in a recognition the Rhesus glycoproteins enable regulated transport of ammonia gas, NH3, which resulted in a paradigm shift shift in the understanding of ammonia metabolism.
