Patricio Ray, M.D., is the Robert Parrott Professor of Pediatric Research at Children’s National Hospital and the George Washington University School of Medicine. He is also an adjunct professor of pediatrics at Georgetown University School of Medicine.  

Dr. Ray received his M.D. winning the “Gold Medal Award” from the University of Buenos Aires, School of Medicine, Argentina, for being the first rank medical student in his class. After completing his pediatric residency and chief residency at the Children’s Hospital “Ricardo Gutierrez” in Buenos Aires, Argentina, he was awarded a prestigious International Research Award from the University of Buenos Aires, School of Medicine, to work at the University of California San Francisco (UCSF) in the U.S. Dr. Ray completed his pediatric nephrology clinical training at UCSF, San Francisco, CA, and subsequently received five years of additional basic research training at the National Institutes of Health, in Bethesda, Maryland. He is currently certified by the American Board of Pediatrics, and the American Sub-Board of Pediatric Nephrology.

As a faculty member at Children’s National, Dr. Ray established one of the first pediatric nephrology research program in the country to study the pathogenesis of HIV-associated renal diseases. His research program at Children’s National has received grant support from four different NIH Institutes. Dr. Ray’s work on the elucidation of the mechanisms by which HIV-1 induces renal injury in children has received national and international recognition. Dr. Ray has published more than 80 articles related to pediatric renal diseases, and is currently exploring the role of heparin binding growth factors in the pathogenesis of acute kidney injury, vascular leakage and bleeding disorders in critically ill children under the sponsor of an NIH RO-1. Dr. Ray also focuses on educational research training efforts for fellows and young faculty at the Children’s National, and underrepresented minority trainees.
