Matters Microbial #131: What Cystic Fibrosis Reveals About Hidden Microbial Lives

Matters Microbial #131: What Cystic Fibrosis Reveals About Hidden Microbial Lives June 3, 2026 Today Dr. Sam Brown, Professor of Biological Sciences at Georgia Tech University, joins the quality quorum today to discuss the social lives of bacterial pathogens. He will also discuss VERY recent research from his lab group exploring the specialist/generalist problem in Pseudomonas aeruginosa, and thoughts on cryptic convergent specialization! Host: Mark O.
