Dr. Vijay Dhar, Medical Director, Neonatology

Recognized for his leadership and expertise, Dr. Dhar serves as medical director of the CHOC Children’s Hospital neonatal intensive care unit (NICU). Dr. Dhar specializes in neonatal critical care, with particular interests in cytokines, nitric oxide, extracorporeal membrane oxygenation (ECMO) and high-frequency oscillating ventilation (HFOV) performed at CHOC.

On the forefront of innovative treatments, Dr. Dhar participates in numerous research studies. As the principal investigator in the NICU Tracheal Aspirate Study, Dr. Dhar and his associates evaluate tracheal aspirate leptin and parathyroid hormone-related protein levels in predicting the development of bronchopulmonary dysplasia.

Driven with a passion for better outcomes for neonates and children, Dr. Dhar is a coinvestigator in the multicenter National Children’s study which examines the effects of the environment, as broadly defined to include factors such as air, water, diet, sound, family dynamics, community and cultural influences, and genetics on the growth, development, and health of children from before birth until age 21 years. The goal of the study is to improve the health and well-being of children and contribute to understanding the role various factors have on health and disease.
