Research Interests<\/h3>\nMy research is to develop new theoretical frameworks and methodologies to unveil the properties of complex phenomena in nature. In particular, the remarkable developments of biology offer us numerous special nonlinear complex systems in which the dynamics implement the “algorithm of life” and embody functions essential for survival in a complex, fluctuating environment. However, due to the highly complex nature of these systems and the difficulties in observing the solely dynamical behavior of an individual molecule free from averaging over an ensemble, the present understanding of fundamental nonlinear phenomena of biomolecules, such as functions, energy storage and transport properties of proteins in cell membranes and organelles, has been no further along than an anatomy or a presupposed thermodynamic energy landscapes on the microscopic levels. By the new methodologies and employing the recent establishments in nonlinear dynamics, information theory and nonequilibrium statistical mechanics, I would like to establish an integrated and quantitative understanding of biological systems, and shed new light on the origin and meaning of life.<\/p>\n
