Dr. Douglas Bush is an Assistant Professor of Pediatrics in the Division of Pediatric Pulmonology in the Jack and Lucy Clark Department of Pediatrics at the Icahn School of Medicine at Mount Sinai and the Mount Sinai Kravis Children's Hospital. After completing his undergraduate studies at Union College and obtaining his medical degree from St. George’s University School of Medicine, he went on to complete  his pediatric residency at Cohen Children’s Medical Center and his pediatric pulmonology fellowship at Children’s Hospital Colorado, part of the University of Colorado. Dr. Bush has studied the genetic and molecular contributions to developing pulmonary hypertension in children with Down syndrome. In particular, he has studied the effects of genetic over-expression of chromosome 21 specific anti-angiogenic factors and their contribution to abnormal lung vascular and airway development.

Although Dr. Bush has expertise in all aspects of pediatric pulmonary disease, he has additional and specific interests in pulmonary hypertension more broadly, severe/refractory asthma, chronic lung disease, rare and interstitial lung disease, technology dependence (tracheostomy and/or chronic ventilator dependence) and other developmental lung disorders such as bronchopulmonary dysplasia.
