Physics Colloquium with Dr. Jay Tang
Active Matter Physics of Bacterial Swarms with Dr. Jay Tang Brown University ABSTRACT: On nutrient-rich substrates, a droplet of motile bacteria can grow into a large swarm. Swarming is a prevalent form of bacterial collective motility, often viewed as a precursor to biofilms. The spreading of a bacterial swarm is facilitated by factors such as osmolytes and biosurfactants, secreted by the dense population of bacteria. Studying Pseudomonas aeruginosa, a human pathogen known to swarm and form...
