To realize a sustainable society, the development of lightweight and high-performance structural materials is essential. Our laboratory combines microscopic structural analysis using electron microscopy with computational simulations to elucidate the fundamental microstructural factors that govern advanced material functionalities.

Main research themes are as follows:

• Design and development of lightweight structural materials with tailored anisotropy
• Elucidation of microstructural evolution processes through multivariate analysis and in-situ observations
• Investigation of nanoscale deformation mechanisms using machine-learning potentials
