The Division of Pediatric Cardiology is home to some of the country's best research aimed at understanding improving the care of children and adults with CHD and children with acquired heart disease. A broad spectrum of research activities spanning basic molecular research, device development, clinical trials and quality improvement initiatives are being pursued by faculty, and all have garnered significant external support. In particular, the Division is an international leader in personalized medicine and the assessment and evaluation of patients with cardiomyopathy and after heart transplantation.

H. Scott Baldwin, MD
Dr. Baldwin’s research has concentrated on delineating the molecular basis of vascular development in the mammalian embryo as an approach to understanding the etiology of congenital heart disease. The ultimate goal of his laboratory is to exploit in utero developmental mechanisms to inform the therapies for postnatal congenital heart and vascular diseases. He is particularly focused on the role of the endocardium in ventricular trabecular and compaction as well as the role of the lymphatic system in mediating additional morbidities and mortalities of patients with CHD.

Justin Godown, MD
Dr. Godown’s research focuses on patient outcomes related to pediatric heart failure, cardiomyopathy, and heart transplantation using novel data analytic strategies including database linkage and advanced machine learning. He is a leader in the use of administrative and billing data to study pediatric heart disease. He is actively investigating processes which impact the availability and utilization of pediatric donor organs through in-depth collaboration with the Association of Organ Procurement Organizations and experts in the field of social and decision-making science. He is also engaged in research to develop novel materials for use in extracorporeal circulation. Dr. Godown is actively involved in multi-center research initiatives through the Pediatric Heart Transplant Society, the Pediatric Cardiomyopathy Registry, and the ACTION learning network. He serves on the Scientific Advisory Committee of the Enduring Hearts Foundation and the Myocarditis Foundation.

Prince J. Kannankeril, MD, MSCI
Dr. Kannankeril is a pediatric electrophysiologist with a Master of Science in Clinical Investigation (MSCI) whose research has been NIH funded for over 15 years. He is Co-Director of the Center for Pediatric Precision Medicine at Vanderbilt, with faculty appointments in both the Vanderbilt Genetics Institute (VGI) and the Vanderbilt Center for Arrhythmia Research and Therapeutics (VanCART). His research program investigates genetic variants and their contribution to cardiovascular disease and clinical outcomes (Personalized Medicine). He is contact PI for the NIH-funded Vanderbilt Integrated Center of Excellence in Maternal and Pediatric Precision Therapeutics (VICE-MPRINT), one of only 2 funded Centers of Excellence in the nation. He has served on the research committee for the Heart Rhythm Society and as Vice President for Research for the Pediatric & Congenital Electrophysiology Society.

Stacy Killen, MD, MSCI
Dr. Killen is a pediatric and fetal cardiologist with expertise in fetal arrhythmias and prenatal diagnosis of complex congenital disease. Her clinical and research efforts seek to improve the care of mothers and fetuses whose pregnancies are complicated by fetal arrhythmias, including supraventricular tachycardia, long QT syndrome, and SS-A antibody-mediated congenital heart block. Dr. Killen is currently participating in several multi-center studies, including studies sponsored by the Fetal Heart Society, that seek to improve treatment approaches and outcomes for patients with fetal arrhythmias and complex congenital heart disease.

Rachel Sullivan, MD
Dr. Sullivan is a pediatric cardiologist with advanced training in pediatric pulmonary hypertension. Her research focuses on examining the role of pulmonary vasodilator therapies in the treatment of pulmonary vascular disease in patients with single ventricle congenital heart disease. She also has interest in evaluating the hemodynamics and treatments for pulmonary hypertension associated with congenital heart disease and bronchopulmonary dysplasia. As a member of the multi-disciplinary Vanderbilt Children’s Pediatric Pulmonary Hypertension Program and North American Pediatric Pulmonary Hypertension Network, she is involved in multi-institutional collaborative research on pediatric pulmonary hypertension.

Jonathan H. Soslow, MD, MSCI
Dr. Soslow is a pediatric cardiologist with advanced training and expertise in pediatric cardiac imaging. He specializes in echocardiography and cardiac magnetic resonance imaging (CMR). He has a Master of Science in Clinical Investigation (MSCI) and focuses his research program on the assessment of serum and imaging biomarkers in Duchenne muscular dystrophy (DMD) cardiomyopathy and after heart transplant. He has been the principal investigator for multiple studies, including an American Heart Association Clinical Research Program grant, a K23 and an R56 funded by the National Heart, Lung, and Blood Institute, and a grant from the Enduring Hearts Foundation. He is currently the PI of a multi-site R01 from the Food and Drug Administration evaluating the longitudinal progression of DMD cardiomyopathy. He is the Director of Clinical Research for the Division of Pediatric Cardiology at Vanderbilt University Medical Center and the Co-Director of the DMD Multispecialty Clinic. He also serves as Co-Chair of the Pediatric Multicenter Research Collaborations Subcommittee for SCMR and on the Steering Committee for the Pediatric and Congenital Heart Disease Section of SCMR.
