He has extensive experience as a physician leader, recently completing a two-year, comprehensive physician leadership program at Advocate Christ Medical Center in Chicago. He has been involved in clinical and translational cancer research for most, if not all, of his career. Dr. Riker enjoys teaching medical students, surgical residents and fellows (surgical oncology, breast oncology). He previously served as Program Director for the surgical breast oncology fellowship.
