He is a Fellow of the American Academy of Pediatrics, the American College of Cardiology and the Heart Rhythm Society.

Dr. Scott's specific area of expertise is cardiac electrophysiology (arrhythmias) and he has a special interest in prevention of sudden cardiac death. He established a comprehensive program for the management of children with arrhythmias upon his arrival and has directed that program since its inception.

Dr. Scott’s research interests are directed at advancing non-invasive technology to diagnose and manage children with congenital and acquired heart disease. He has authored many peer reviewed publications and book chapters.
