Research Overview

Dr. Levy is co-lead of the SmallWonders research group, which focuses on using real-time hemodynamic and cardiovascular data to guide precision care in critically ill newborns with heart disease. The team develops and validates noninvasive imaging and biomarkers to improve diagnosis and treatment in neonatal and pediatric patients. Their work, part of national and international collaborations, explores noninvasive measures of cardiac and pulmonary function in preterm infants to better understand postnatal cardiac adaptation. Conditions studied include patent ductus arteriosus, pulmonary hypertension, bronchopulmonary dysplasia, pulmonary vein stenosis, and congenital heart disease. The group takes a physiologic, interdisciplinary approach to managing neonatal cardiorespiratory disorders, with ongoing collaborations across cardiology and neurodevelopmental science.

Research Background

Dr. Levy is a clinician-scientist dedicated to excellence in neonatal cardiovascular care, research, and education. His work focuses on innovative approaches to understanding congenital and acquired heart diseases in newborns, with expertise in advanced cardiac imaging, neonatal lung disease, resuscitation, and complex care for preterm infants with heart conditions. He has received support from NIH and institutional grants and built a broad network of national and international collaborators to advance cardiac phenotyping in newborns. Dr. Levy is a founding member of the Neonatal Hemodynamic Research Center, co-leads the New England Premature PDA Closure Program, directs the neonatal consultation program at Boston Children’s Hospital, and serves as a liaison between the Newborn Medicine division and the Heart Center at Boston Children's Hospital.
