David A. Ziring MD

David Ziring, MD, has dedicated his life to helping children with inflammatory bowel disease (IBD). He received his medical degree from the Chicago Medical School while earning his master's degree in clinical immunology. Dr. Ziring went on to receive residency training in pediatrics at Children's Hospital Orange County, then pursued subspecialty training in Pediatric Gastroenterology at UCLA David Geffen School of Medicine with Marvin Ament, MD, and associated faculty. At UCLA, Dr. Ziring concentrated his research efforts on the regulation of the immune system in IBD with research mentor, Jonathan Braun, MD. Dr. Ziring was instrumental in describing the contribution of the gene CNR2 to IBD pathogenesis, working with collaborators at Cedars-Sinai. He has since migrated research interests from working in the laboratory with animal models to studies involving patients with IBD. This work resulted in the award of a Broad Medical Research Program grant to study the immunomodulatory effects of large doses of vitamin D in children with Crohn's disease. Besides his research and direct patient care, Dr. Ziring works closely with the IBD community.
He serves as medical director of the Crohn's & Colitis Foundation of America's national Team Challenge half marathons, with events in Napa, San Antonio, Miami and Hawaii that have raised more than $30 million. He has been a volunteer physician for the past eight years with the CCFA's summer program Camp Oasis, caring for more than 120 children with IBD each summer. Dr. Ziring serves as the primary investigator and UCLA's representative for the CCFA's national pediatric research network PROKIIDS and is a member of the IBD Committee for the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition. He has spoken at regional academic centers on topics from skeletal health in children with IBD to the transition of care of teens with IBD.
