Research Subject

The autonomous behaviors of a cell, the minimum unit of living organisms, are performed by soft bio-matters that are driven both by thermal and athermal forces. Dynamic response and process in cells are frequently nonlinear and far from equilibrium, and therefore statistical physics that governs the behavior of cells and tissues is still elusive.
In this project, we study the kinetics of the nonlinear and non-equilibrium bio-matter systems by performing active/passive microheology. We investigate the intricate relations between fluctuation and the dynamics response of bio-matter which is driven by artificially or spontaneously generated athermal fields.
Our aim of this project is to study (1) the fluctuation in non-equilibrium system under a strong multi-object interaction, and (2) the non-equilibrium dynamics of the intracellular environment as athermally driven glassy materials. These experimental studies clarify the physics underlying the living systems.
