| Research Abstract |
We have carried out theoretical analysis and development of numerical method for studying various macroscopic and microscopic pattern formation in material sciences. In particular, we have investigated both numerically and analytically
(1) structural transitions of mesophases in block copolymer melts
(2) ordering dynamics of charged colloidal particles
(3) dynamics of grain boundaries
(4) domains dynamics of reactive phase separating systems and
(5) formation of bacteria colony with chemotacsis.
Some of these works have been performed in collaboration with experimentalists.
Together with these studies, we have also developed fundamental theories of interface/grain boundary dynamics by means of singular perturbation and reduction method.
