Biography

Dr. Gong is currently Associate Professor of Medicine and Physician Scientist at the Nephrology Division of Brown Medical School in Providence, Rhode Island. Dr. Gong earned his MD degree from Nanjing University School of Medicine in Nanjing, China. He received his internal medicine residency and nephrology fellowship training at the Jinling Hospital of Nanjing University, where he gained extensive experience in glomerulonephritis, transplantation immunology, renal pathology and molecular nephrology. Afterwards, he earned his doctorate in Renal Physiology in 2001 under the mentorship of Drs. Zhihong Liu and Leishi Li, the thesis being “Epistasis in common kidney diseases”. He joined the full-time faculty at Brown University after completing postdoctoral research training with Dr. Lance Dworkin in 2004. Dr. Gongs research interests center on pathogenesis and therapy of glomerulopathies, in particular podocytopathies; and pathogenic mechanisms of renal fibrogenesis and inflammation. His other research interests include epistasis in common kidney diseases; immunopathogenesis of lupus nephritis; and mechanisms of acute and chronic kidney injury, repair and regeneration. His research has been well funded by the US National Institutes of Health, private foundations and industry, and has been very active and productive with over 50 original peer-reviewed scientific publications as well as book chapters and patents.

Research Interest

His research interests include: Mechanisms of kidney injury, repair and regeneration. Current research projects in his lab include: Pathogenic mechanisms and novel treatments of glomerulopathies, Pathogenic mechanisms of acute kidney injury (AKI) and post-AKI transition to chronic kidney disease, Cell signaling mechanisms involved in chronic renal fibrogenesis or scarring, The pathogenesis and treatment of renal inflammation.
