Research & Publications


Dr. Alexander Hillel's clinical practice and research focuses centers on risk factors for, the prevention of, and treatment for laryngotracheal stenosis (LTS) and other diseases of the trachea and larynx. His laboratory developed robust in vitro and in vivo model systems to study immunologic and metabolic mechanisms promoting laryngotracheal inflammation, airway wall remodeling, and fibrosis to develop new therapies targeting airway disease. Ongoing efforts include applying a novel drug-eluting stent to influence to treat laryngotracheal stenosis. He serves on the leadership team of the North American Airway Collaborative (NoAAC) which is an international organization dedicated to improving our understanding of adult airway disease and developing effective, cost-conscious treatments.
