My Biography & Research


Dr. Brewington cares for patient with a wide variety of airway and lung diseases. He has a particular interest in the care of patients with cystic fibrosis, congenital airway malformations, and chronic respiratory failure. His research focuses primarily on cystic fibrosis, with a goal of maximizing the clinical benefits of new "modulator" drugs at the individual patient level. His work investigates possible drug-drug interactions between traditional CF therapies and these novel drugs, as well as personalized model systems to predict and study drug benefit for an individual patient. He is also interested in medical education, including residency and fellowship training, as well as formal training in flexible bronchoscopy.
