Ph. D. (Engineering), Assistant Professor
Department of Materials Science and Engineering,d
Graduate School of Engineering, Kyoto University, Japan.
I’m working on fundamental studies of physical metallurgy in various solid solution alloys. I’m interested in the relationship between nano/microstructures and macroscopic mechanical/physical properties of metals and alloys and characterizing microstructures by using advanced electron microscopy and quantum beam diffraction techniques.
