Academic Degree
Doctor of Engineering
Country of degree conferring institution (Overseas)
Field of Specialization
nonlinear physics, pattern formation, crystal growth, fractal, sociological physics, complex systems
Outline Activities
I mainly study pattern formations such as dendrite, dense-branching morphology and fractal diffusion-limited aggregation in diffusion field, which are related with nonlinear and non-equilibrium phenomena.
I give some lectures of physics for undergraduate students at Ropponmatsu campus and some lectures for graduate students in Interdisciplinary graduate school of engineering sciences at Chikusi campus.
I gave lectures at Hoso University in 1999.
[social activities]
I was a maneger of crystal growth section of the physical society of Japan and have been an editor of the journal of The Society for Sciences on Form, japan, "FORMA".
Research Interests
  • We have studied statistical properties(statistics/dynamics) of approval ratings of several governments in the view points of complexed science or sociological physics.
    keyword : complexed science, sociological physics
  • pattern formation in nonlinear and non-equilibrium systems
    keyword : nonlinear physics, non-equilibrium phenomena, pattern formation in diffusion field, dendrite, fractal, finger print, Tsallis statistical physics, sociological physics, complexed science
    1983.04~2018.03I have studied pattern formation in diffusion field as nonlinear and non-equilibrium phenomena with experiments and computer simulations. The diffusion field makes dendrite, fractal pattern, dense-branching morphology and so on. We have understood, for example, the growing mechanism of the tip of dendrite. And, we are studying the mechanism of growing side-branches of the dendrite..
