Research topics

 The main subject is the development of science in materials microscopic processes by interaction between high energy electrons and materials. Materials nano-processes induced by knock-on displacements and electronic excitation effects and non-equilibrium phase formations driven by the synergy effects with nano-size effect have been studied by in-situ ultra-high voltage electron microscopy. Our research interests are focused on the materials science under dynamic non-equilibrium states. The main subject of our biological research is the relationship between the structural change of macromolecules and its function.
 Current research programs are as follows.
(1) Electron-irradiation-induced non-equilibrium phase formation
(2) Specific structural properties in nanoparticles and soft materials
(3) Localization of biological complexes in cell by electron tomography
