Dr. Kitagawa received the B.S. degree in physics from Kyoto University, Japan in 1993, and the M.S. and Ph.D. degrees in physics from the University of Tokyo, Japan in 1995 and 1998, respectively. At the University of Tokyo, he carried out materials research on rare-earth intermetallic compounds showing quadrupolar orderings. In 2002 he joined Hiroshima University, Japan as a research associate. He was then engaged in the study of material properties using the terahertz (THz) time-domain spectroscopic method and the development of THz devices. In 2012 he joined Fukuoka Institute of Technology, Japan: from 2012 to 2014 as an associate professor, and from 2015 as a professor. His research interests include materials research on magnetic and superconducting materials. The current projects are magnetism and superconductivity in high-entropy alloys and chemical control of the magnetic state in a compound with a complex crystal structure.
