Professor Of Physics Kyoung-Jin Lee is a biophysicist working in on nonlinear, non-equilibrium, and many-body systems. He obtained his Ph.D. (1994) from the University of Texas - Austin, and before coming to Korea University he was a research associate at Princeton. Research Interests Broadly speaking, I am interested in biophysical problems in which nonlinear, non-equilibrium, many-body system approach (i.e., patterns and waves) plays an important role. They are ubiquitous in nature: by all means, "living creatures" are composed of many interacting cells that are inherently nonlinear and often self-organizing to make various dynamic structures and forms. My laboratory is exploring several different issues ranging from "neural learning and memory" to "density waves in populations of tumor cells."
