I research how bacterial pathogens interact and evolve during chronic infections, especially in the long-lived lung infections that affect people with the genetic disorder cystic fibrosis. I am also a founder member of the interdisciplinary AncientBiotics consortium, which seeks to identify, reconstruct and test infection remedies from medieval medical books in the hope of finding new agents to treat antibiotic-resistant infections.
