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).
