Ngoc P. Ly, MD, MPH

Chief of Pediatric Pulmonary Medicine

Dr. Ngoc P. Ly is a specialist in diagnosing and managing acute and chronic respiratory diseases in children. Her expertise encompasses lung function testing, exercise testing and bronchoscopy (passing a flexible instrument into the lungs to view the airways). She has a special interest in caring for children with asthma and other chronic lung diseases.

Ly directs the UCSF Asthma Program, which provides comprehensive diagnosis and treatment services for asthma in children, with a focus on severe asthma. The program's care team includes a nurse practitioner and respiratory therapist certified in asthma education, with the goal of helping patients and their families to better understand and manage the condition. Ly also directs UCSF's fellowship program in pediatric pulmonology.

Ly earned her medical degree from the University of Rochester. She completed her residency in pediatrics at Virginia Commonwealth University School of Medicine. She completed a fellowship in pediatric pulmonary medicine at MassGeneral for Children, an affiliate of Harvard Medical School, and then completed a research fellowship in respiratory and environmental epidemiology at the Channing Laboratory, part of the Harvard T.H. Chan School of Public Health, where she also received her master of public health degree.
