Julia Emerson, MD, MPH

Julia C. Emerson, MD, MPH, is an epidemiologist in the Division of Pulmonary Medicine at Seattle Children’s Hospital and lecturer in the Department of Pediatrics at the University of Washington School of Medicine. Emerson’s research interests include the natural history of early cystic fibrosis (CF) lung disease, the design of clinical trials to improve CF therapies and the development of better outcome measures for CF clinical protocols. She also collaborates on studies of the genotypic and phenotypic changes in airway pathogens that may be associated with CF lung disease severity and progression.
