Bio

Dr. Ariel Feldstein is chief of the Gastroenterology, Hepatology & Nutrition Division at Rady Children's Hospital-San Diego and a professor of pediatrics at UC San Diego School of Medicine.

After graduating from the Universidad de Buenos Aires Medical School and completing a postdoctoratal program in physiology at the Mayo Clinic, Dr. Feldstein went on to become the director of research for the Pediatric Institute at the Cleveland Clinic before moving to San Diego in 2011.

Dr. Feldstein oversees one of the largest pediatric gastroenterology divisions in the country, which is a top-ranked program by US News & World Report. He is a renowned pediatric hepatologist who pioneered the development of non-invasive blood tests to monitor liver damage. His research is supported by several grants from the National Institutes of Health, professional associations such as the American College of Gastroenterology and pharmaceutical industry leaders. He and his lab have made significant contributions to understanding and developing therapies for obesity-associated liver disease, now the most common form of chronic liver disease in children.

Dr. Feldstein has published over 120 peer-reviewed publications in various medical journals. He currently serves as the associate editor of Seminars for Liver Disease and has held editorial positions on other gastroenterology and hepatology journals. He is a member of the Society for Pediatric Research and numerous specialty societies and has held leadership roles in the American Gastroenterological Association and the American Association for the Study of Liver Diseases.

His goal is to use his research to develop safe and effective diagnostic and therapeutic strategies for patients with highly prevalent and potentially serious conditions.
