Chronic infection and Cystic Fibrosis Research

Our lab seeks to improve understanding of chronic bacterial infections and to devise new diagnostic and therapeutic approaches. We focus on the opportunistic pathogen Pseudomonas aeruginosa, other Gram negative organisms, and microbiome analyses to study chronic infections that afflict people with cystic fibrosis and other diseases.

We use genomic, evolutionary, and molecular biology approaches in multi-disciplinary research that involves microbiologists, genome scientists, physicians, immunologists, and clinical researchers. We are located in the School of Medicine at the University of Washington in Seattle.
