My interest in pediatric pulmonology started early in my training, when I had the opportunity to work in an asthma clinic for children. I chose to specialize in lung diseases affecting children because this population is very special; they are both inherently vulnerable but also remarkably resilient. I love developing relationships with my patients and their families and consider it a privilege to take part in their care. Children are referred to me for a variety of reasons, such as difficulty breathing, frequent cough, difficulty exercising, snoring, swallowing problems, weakness, prematurity, and frequent lung infections. Left untreated, many of the underlying conditions causing these symptoms can have severe long term effects. It is essential that growing children are able to sleep well, breathe comfortably, be physically active, and receive adequate nutrition safely. I work with families, my colleagues, and physicians in other medical specialties to ensure that my patients reach these goals. My research interests have been primarily related to basic mechanisms driving inflammation in patients with asthma. In our laboratory, I work with other pulmonologists and scientists to study the roles of various proteins produced by our body and how they can worsen or mitigate asthma. More recently, I have started to study how these proteins affect lung development in babies. Another one of my interests is medical education, and I am involved in an innovative project designing instructional tools to teach doctors in training more about pediatric pulmonology.

Marc Richmond, MD, MS is an Associate Professor of Pediatrics at CUMC, and the Associate Medical Director of the Program for Pediatric Cardiomyopathy, Heart Failure and Transplantation. He specializes in caring for the child with heart failure due to cardiomyopathy, congenital heart disease or acquired cardiac disorders as well as caring for children after heart transplantation for such indications. Dr. Richmond additionally sees patients as part of the Cardiac Genetics Program and in the Comprehensive Muscular Dystrophy Clinic. His clinical and research interests are focused upon improving clinical outcomes for children with heart failure or transplantation, evaluating cardiac function using newer noninvasive techniques as well as an interest in the use of ventricular assist devices for children with severe decompensated heart failure. Furthermore, he serves as the Vice-President of the multi-center Pediatric Heart Transplant Study Group and is actively involved in the multi-center Pediatric Heart Network and Cooperative Clinical Trials in Pediatric Transplantation.

Dr. Mark Liszewski is a board certified radiologist with subspecialty certification in pediatric radiology. He is an associate professor of radiology at Columbia University Irving Medical Center, vice chair of radiology at NewYork-Presbyterian Morgan Stanley Children’s Hospital and chief of the Division of Pediatric Radiology. As a pediatric radiologist, Dr. Liszewski works with pediatricians and pediatric specialists to provide family centered diagnostic imaging services attuned to the needs of children. Dr. Liszewski earned his medical degree from the Albert Einstein College of Medicine where he was inducted to the Alpha Omega Alpha Honor Medical Society. He completed an Internal Medicine Internship at Beth Israel Deaconess Medical Center/Harvard Medical School which was followed by a Radiology Residency at Brigham and Women’s Hospital/Harvard Medical School where he was elected to serve as chief resident. He then completed a Pediatric Radiology Fellowship at Boston Children’s Hospital/Harvard Medical School where he served as chief fellow. Prior to joining faculty at Columbia, Dr. Liszewski was the vice chair of outpatient imaging, chief of the Division of Pediatric Radiology, and an associate program director for the Radiology Residency at Montefiore Medical Center. Dr. Liszewski is a nationally recognized leader in pediatric radiology and is a frequently invited speaker and panelist at national and international conferences. Dr. Liszewski has chaired and served on multiple hospital committees and academic committees of leading radiology organizations including the American Board of Radiology and American College of Radiology. He has served as an assistant editor for the American Journal of Roentgenology, Pediatric Imaging Section and has been recognized with awards including the Ralph Ger Award and the Golding Scholar Award. Dr. Liszewski’s research focuses on innovations in pediatric imaging with particular interest in pediatric thoracic, gastrointestinal and vascular disease. He has also worked to develop novel bedside fluoroscopy techniques for children.
