    Collapse Overview
    My research has focused on the influences of heredity, as well as prenatal and infant environmental exposures ( including environmental, microbial, and nutritional influences) on immune responses and clinical symptoms of allergy and asthma. I have been actively involved and collaborated with investigators on 4 large prospective birth cohort studies and a cross-sectional study relating to environmental and immunological determinants of allergy and asthma.

    Clinically, I oversee and direct care for a large number of asthmatic children in the Pediatric Pulmonary Asthma Program at UCSF that I established in 2009. The Asthma Program consists of an asthma care team that includes a nurse practitioner and respiratory therapist certified in asthma education to facilitate asthma education and management for children less than 18 years of age.

    My other clinical interests include bronchopulmonary dysplasia (BPD), congenital lung abnormalities, interstitial lung diseases, chronic respiratory failure/insufficiency and neuromuscular respiratory diseases, including assistive therapies such as oxygen, mechanical ventilation, airway clearance devices, or an artificial airway.
