Recent single molecule detection techniques have revealed unique mechanism of actomyosin molecular motor.

Molecular motor moves unidirectionally with using Brownian motion (thermal fluctuation). Such molecular motors are well organized in muscle systems, which can control their spatiotemporal dynamics according to various conditions.

In this study, molecular motor is postulated as an information-processing unit based on Brownian motion, and muscle as organized system based on these Brownian units.

By modeling and experimental testing for molecular motor system, I will try to understand and create dynamic controlling mechanism realizing such dynamic behaviors of bio systems.
