Biography Summary

David J. Keljo, MD, PhD, is a pediatric gastroenterologist at Children's Hospital of Pittsburgh, director of the hospital's Inflammatory Bowel Disease Program and a professor of pediatrics at the University of Pittsburgh School of Medicine.

Dr. Keljo earned a bachelor's degree in chemistry from Yale University, graduating magna cum laude with departmental honors in 1971. He earned his medical degree from the University of Pennsylvania School of Medicine, where he was awarded the R.G. Williams Prize for Research by an undergraduate. Dr. Keljo also earned a doctorate in physiology from the University of Pennsylvania Graduate School of Arts and Sciences. He completed his residency in pediatrics at Children's Hospital Boston, Harvard Medical School, and a fellowship in pediatric gastroenterology at the Hospital for Sick Children, University of Toronto, where he was awarded the Tisdall Prize for Research by a fellow.

Dr. Keljo's research program seeks to better understand inflammatory bowel disease and improve treatment. His research interests include examining the time course and effects of therapy on bone density to optimize bone development in patients with inflammatory bowel disease. Assessment of disease activity currently relies on symptoms such as abdominal pain, which can have many causes other than inflammatory bowel disease. More reliable measurement of disease activity will help to improve studies of treatment for inflammatory bowel disease.

He has been published in many notable publications, including Current Gastroenterology Reports and Current Treatment Options in Gastroenterology.
