He is interested in the coloration phenomena in nature that utilizes sub-wavelength structures. He has investigated many natural examples including brilliantly colored butterfly wings, beetles’ elytra, bird feathers, and fish.

He studied physics at Hokkaido University, and received PhD in femtosecond time-resolved laser spectroscopy (1998). Then, he studied the low frequency response of molecular liquids as a postdoctoral fellow at Osaka University (1999). He was a research associate of Graduate School of Science of Osaka University from 2000 to 2001, and moved to newly founded Graduate School of Frontier Biosciences (2002).
