Message for Students

A real-world phenomenon is complex and flexible. Theoretical analysis would give us a simple view of seemingly complex things. With the help of mathematical modelling, computational science, and machine learning, let us work together to understand your exciting things, and share them with others.

Research Contents

Our group is theoretically studying the dynamics of pattern formation. A particular focus is on soft materials, such as polymers in gels, liquid crystals used TV, and biological cells. Those systems are very complex, but with the aid of machine learning, we may estimate mathematical models to understand them.

Attractive Factors of My Research

Nature is full of interesting phenomena. Understanding a small piece of it gives us new insight which nobody has done. A natural phenomonon is very complex, but still, it is often understood by simple theoretical idea. Mathematical science would help us find common aspects of completely different phenomena. Research would lead you to these experiences.

Achievement

Our group has proposed a machine-learning approach to estimate governing equations for the pattern formation of polymers and colloidal particles. Our research incudes nonlinear waves of proteins which play an essential role on cell division, modelling of self-propelled drops, and theoretical models for periodic patterns in cytoskelton.
