Hyperordered Structures in Materials

Koichi Hayashi was born in Kagoshima, Japan, in 1968. He obtained his B.Sc. (1990) and M.Sc. (1992) degrees from Kyushu University, and D.Sc. (1996) degree from Kyoto University. He was a research associate in Kyoto University (1996–2000) and Tohoku University (2000–2003). Then, he promoted to an associate professor (2003–2015) in Tohoku University. He moved to Nagoya Institute of Technology as a full professor in 2015. He has been engaged in developments of new X-ray analysis methods to date. Recently, he has investigated local structures around dopants in state-of-the-arts materials by means of XFH. In November 2020, he launched a huge national project (JSPS Grant-in-Aid for Transformative Research Areas (A)) of “Hyper-ordered Structures Science” as a representative.
