研究の背景 Background


To create a mathematical model for a variety of phenomena, we would like to establish a methodology for understanding by using numerical calculation. Even if we could not find a commonality in phenomenon, in the process of creating a mathematical model, we might be able to find a commonality. I will research for “to find a general rule of lurking on the phenomenon”.

研究の目標 Outcome


In biological systems, I study about morphogenesis. Form of the organism has a close relationship with its function. Until now, I study about several mathematical model (ex. A mathematical model of cell cleavage, planar cell polarity, and the dynamics model for Drosophila hindgut). On the other hand, I am interested in quadruped locomotion system and phenomenon of related cognition to of the human brain.
