Field of Research:
Materials science and engineering, in particular, in the areas of metals, alloys and oxides, materials design, computational materials science, etc.
Research Interests:
One of my main interests is the computer-aided materials design. With the aid of quantum mechanical calculation methods such as the DV-Xa molecular orbital method and the plane-wave pseudopotential method, most properties of alloys and ceramics can be understood in view of the nature of the chemical bond. The use of the concept for materials design constructed on the basis of such fundamental understanding, makes materials development more efficient, compared to the current trial-and-error experimental method. Also, my attention is directed toward the simulation of localized quantum structures formed in those alloys and ceramics which are decorated with light elements such as hydrogen and lithium. Furthermore, my current interest is focusing on the process simulation of multi-functional materials with fine structures using the phase-field method as well as quantum mechanical calculation methods.
