She is a pediatrician and health services researcher, and is the Director of the Center for Healthcare Research in Pediatrics (CHeRP). Dr. Wu is also leading the Age-Dependent Pharmacogenomics of Asthma Treatment (ADAPT) study; this research will link genetic variants to therapeutic responses with additional information from genomics and metabolomics to provide insight into the biologic pathways that may be activated in an age-dependent method. This study will elucidate response to the two most commonly used medications for asthma, inhaled steroids and β2-agonists. Her research interests are in health disparities, asthma, and pharmacogenetics.
