Math Biology Seminar: Lewis Liu (CANCELLED)

Due to inclement weather, this talk has been cancelled and will be rescheduled for a later date.

Bacteria collective migration can spontaneously emerge when individuals follow common rules of interaction (chemotaxis), and a biased leakage during the migration can be observed, but it remains unclear how these behaviors are achieved. The traditional Keller-Segel model is successful in modeling chemotactic migration of a single phenotype in population/distribution level, in this talk we will introduce diversity to the model to study the collective migration. We reveal the mechanism behind collective migration through ‘analysis’ and numerical simulations. And we also make a connection to the Ornstein-Uhlenbeck process and Langevin equation to investigate the biased leakage. This is a joint-work with Xiongfei Fu and Yang Bai.
