The major field of my research topic is mechanical materials and mechanis of materials. Especially, research topics on solid mechanics and continuum mechanics based on computational and experimental mechanics are been working on. Multi-scale modeling of phase transformation with interface dynamics in the metallic materials and the confirmation of its validity by experiment have been done. Recently, the research field related to impact engineering is interesting. The topics concerning with impact engineering and its applications to the aerospace and automotive industries are also been working on.
