In 2000, he was appointed as the President of the Tokyo Chapter, LEOS, IEEE. From 2000, He is an executive director of the Japan Society of Applied Physics. His main field of interests is nanophotonics.He is a Fellow of the Optical Society of America, and a Fellow of the Japan Society of Applied Physics. He is also a Tandem Member of the Science Council of Japan. Awards: 14 prizes from academic institutions, including the Distinguished Achievement Award from the Institute of Electronics, Information and Communication Engineering of Japan in 2007, the Julius Springer Prize for Applied Physics in 2009.

Masahiro Irie received his B.S. and M.S. degrees from Kyoto University and his Ph.D. degree in radiation chemistry from Osaka University. He started his research on photochemistry at Hokkaido University in 1970 and went on to Osaka University. In 1988 he was appointed to Professor at Kyushu University, where he initiated the study of photochromic diarylethene derivatives. He is currently interested in developing single-crystalline photochromism and single-molecule photochemistry using diarylethene derivatives.
