Research Interests:

  Most of planetary materials have a crystalline structure, in which constituent atoms are packed in a repeating pattern extending in all spatial dimensions. Those crystals (minerals) respond to changes in the terrestrial and extraterrestrial environment with various physical and chemical changes; e.g. phase transformation, exsolution and diffusion. In other words, investigations of minerals provide us curriculum vitae of the Earth and Planets. Merely identifying minerals without appreciating its significance is nothing but a work of amateur collectors. I am aiming to read information about the origin and the evolution in terrestrial materials, meteorites and synthetic samples using various experimental methods (electron microscopy, micro-probe analysis, spectroscopy, diffraction and so on).

Current research projects:
1. Examinations of micro-textures and symmetry in Earth and planetary materials using electron microscopy.
2. Diffraction study on high pressure and high temperature materials using synchrotron X-ray.
3. Developments of computer software on X-ray and electron crystallography.
