Research Summary

Our research focuses on understanding interactions between microbial species during airway infection in individuals with cystic fibrosis. Data from our lab and others reveal interspecies interactions can alter microbial metabolism, motility, antibiotic tolerance, and production of virulence factors. We seek to understand the cellular mechanisms driving these interactions in order to modulate polymicrobial community behavior and improve patient outcomes. We utilize live-cell imaging, bacterial genetics, and molecular biology approaches to interrogate polymicrobial interactions at the population and single-cell level, in both in vitro models of infection and in ex vivo patient samples.
