Dr. Shannon was born in Cincinnati Ohio, attended Xavier University and Stritch School of Medicine, Loyola University Chicago. He served as pediatrician at Hanscom Air Force Base, Massachusetts before becoming a Teaching Fellow at Massachusetts General Hospital (MGH), Boston, Massachusetts.

Dr. Shannon was a physician-scientist who made significant contributions to pediatric healthcare. He developed one of our nation’s first Intensive Care Units for infants and children, and also founded the Pediatric Pulmonary Division at MGH. Through groundbreaking research and clinical practice, he introduced new procedures to pediatrics which remain the standard of care today. He was also instrumental in the creation of the Athinoula A. Martinos Center for Biomedical Imaging at MGH. In 2014, he authored “Innovations in Pediatrics, Massachusetts General Hospital 1910-2010”.

As a founding faculty member of the Harvard-MIT Health, Science and Technology Program (HST), Dr. Shannon helped develop this widely influential model for medical education. He vividly taught his students the power of integrating medicine with basic science and engineering to advance human health. As Director of Admissions and Faculty Development, he helped build an exceptionally diverse and rigorous HST community to promote collaboration and health equity.
