Research interests include renal pharmacology, animal models of ckd progression and ckd related hypertension and the use of biomarkers in transplantation and care of ESRD patients. Current interest involve the use of the 5/6 nephrectomy rat and mouse models of CKD. Of particular interest has been the delineation of mechanisms of renal protection, particularly using curcumin as one such agent that seems to ameliorate the rate of ckd progression. Active collaboration with investigators within the Department of Internal Medicine and in the Department of Pharmacology and Toxicology occur. Another focus has been the development of an animal model of hepatorenal syndrome through active collaboration with the Hepatology Division. Multiple areas of clinical investigation include novel treatments for acute kidney injury, the use of biomarkers to diagnose renal allograft rejection, novel treatments of hypertension, delineating hemodynamic and renal effects of paracentesis in patients with cirrhosis, and the impact of daily dialysis on dialysis patient outcomes. Dr. Gehr has received numerous teaching awards from Medical Students and Internal Medicine Housestaff and has published more than 75 articles.

Dr. Gehr and his family have lived in Richmond for more than 20 years. Lynne, his wife, is an Anesthesiologist at VCUHS and they have two daughters. He and his wife enjoy skiing, sailing, fishing, hiking and scuba diving.
