About Me
My clinical interests include the non-invasive assessment of congenital heart disease in the fetus to the adult, with a particular focus in fetal cardiology and patients with single ventricles. I am the director of Duke Pediatric Noninvasive Cardiac Imaging and I am an attending physician in the Duke Cardiovascular Magnetic Resonance Center. I am an American citizen who was born in England and raised in Canada. I have lived in the United States since I received my undergraduate education at Cornell University. I joined the Duke Children’s Heart Program in 2004.

Ratings and Reviews
The ratings and reviews are based on patient responses to the overall provider rating question from the survey. The question reads: “Using any number from 0 to 10, where 0 is the worst provider possible and 10 is the best provider possible, what number would you use to rate this provider?” Responses are converted to a 5-point rating system and applied consistently to all providers. Learn more about our survey process. Patients who see some types of providers receive a different version of the patient satisfaction survey. Those results are not available on DukeHealth.org.

Clinical Focus and Research
My research investigates novel technologies in imaging the heart for structure and physiology in conjunction with the North Carolina State University College of Veterinary Medicine, changes in cardiac function with exercise, assessment of myocardial mechanics, and how to provide the best care to newborn infants with prenatally diagnosed heart disease that balances infant stability with family bonding. I am equally committed to cardiovascular education and investigating methods to best deliver pediatric cardiology training to the global health community.
