John S. Gunn

John S. Gunn studies how bacterial pathogens like Salmonella and Francisella cause chronic infections, focusing on biofilms (protective bacterial communities that resist antibiotics and immune attack) and the signaling systems bacteria use to sense their environment. Much of the work uses mouse models to understand chronic Salmonella carriage (such as in the gallbladder) and to test new anti-biofilm compounds, sometimes combined with antibiotics like ciprofloxacin. The research aims to develop better methods for detecting persistent infections and new therapeutic strategies against biofilm-related bacterial disease.

Publication output has fluctuated over the last decade, rising to peaks in 2021 and 2024 but generally averaging fewer than 5 papers per year in the most recent 5-year period, suggesting a somewhat variable rather than steadily growing pace.
