Education and Training

Sripriya Sundararajan is an Associate Professor in the Division of Neonatology at University of Maryland. She originally received her MD in Pediatrics from Chennai Medical College, India after completing medical school from Stanley Medical College, India. She recertified in Pediatrics and completed her fellowship training in Neonatal-Perinatal Medicine from the University of Virginia. She is a member of the American Academy of Pediatrics, section member of Neonatal-Perinatal Medicine, member of the Society for Pediatric Research and member of the Eastern Society for Pediatric Research.



Dr. Sundararajan's research focuses on improving patient outcomes in preterm infants by reducing morbidities including necrotizing enterocolitis and retinopathy of prematurity. Dr Sundararajan studies the impact of red blood cell (RBC) transfusions on preterm infants and the benefits of placental transfusion associated with delayed cord clamping. Dr Sundararajan has established standardized guidelines for blood product use including RBC and Platelet transfusions in the NICU. She led a multidisciplinary institutional effort to incorporate delayed cord clamping into clinical practice. She has played a significant role in reducing hypothermia in neonates after delivery by enforcing the WARM bundle in the Labor and Delivery unit at UMMC. Dr Sundararajan also worked collaboratively with MFM., Pediatric Cardiology, and PCICU in revising the neonatal cardiac classification and criteria for the disposition of high-risk infants with critical congenital heart disease at UMMC. 

As the Medical Director of a level IV Neonatal Intensive Care Unit in the state of Maryland, Dr Sundararajan oversees highly complex patients and creates solutions to make things better. She leads the clinical mission by incorporating evidence to create guidelines; developing systems that evaluate, monitor, and improve patient and team-based care; coordinating care among obstetric and pediatric subspecialty providers; mediating conflict between providers and with families; and acting as a liaison between the NICU staff and administration. As the Neonatal Director of OB-MFM relations, Dr Sundararajan facilitates consultation with high-risk pregnant mothers by working closely with the Maternal-Fetal Medicine group at UMMC. Dr Sundararajan is actively involved in medical student education through participation as a preceptor for Practice of Medicine (POM-2) course and Pediatric Clerkship rotations. 

Research/Clinical Keywords

Neonatal red blood cell transfusion, hypothermia reduction in the delivery room and at NICU admission, delayed cord clamping and study of intestinal permeability in very low birth weight infants
