Dr. Stephan R. Targan, Director of the Inflammatory Bowel and Immunobiology Research Institute at Cedars-Sinai, has been focused on finding solutions to complex scientific problems ever since childhood. Drawn to the study of IBD because, he says, “it was one of the most difficult puzzles to solve,” Dr. Targan has become one of the IBD field’s most renowned physician scientists. Perhaps one of his most significant contributions to the field is his training and mentorship of hundreds of physicians, locally and globally, who have emerged as international thought leaders in their own right, creating a positive ripple effect that has benefitted patients worldwide.
