报告人简介:Yong Jung Kim (金容政) was born in Seoul, Korea, in 1965, where he lived until 1992 and finished undergraduate study at Seoul National University. He studied mathematics in USA for his Ph.D. program at University of Wisconsin. He studied Analysis and Partial Differential Equations and completed his Ph.D. under the supervision of Athanasios Tzavaras. He started his research on hyperbolic conservation laws. Recently he is interested in modeling of biological phenomena related ecology, pattern formation, population dynamics, etc.

Abstract: Classical chemotaxis theory is based on the assumption that microscopic scale bacteria sense the macroscopic scale chemical gradient. In this talk we will take diffusion models with spatial heterogeneity and apply them to obtain chemotaxis phenomena. We will see that the assumption of sensing the gradient is not essential in the chemotaxis theory.
