PHYSICAL MATHEMATICS SEMINAR TOPIC: STUDIES OF BACTERIAL COOPERATIVE ORGANIZATION USING REACTION-DIFFUSION MODELS SPEAKER: IDO GOLDING School of Physics and Astronomy Tel Aviv University ABSTRACT: We formulate a reaction-diffusion model for bacterial branching growth, and use this model to study possible scenarios during the life of a colony: The use of chemotactic signaling, the appearance of chirality, the emergence of mutations and the stress of antibiotics."
