After I received my Ph.D. at the University of Tokyo in 1991, I shortly stayed at the University of Hawaii for Pos-Doc. research, and moved to the Geological Survey of Japan as a researcher in 1993. My main field is marine geology using a reflection seismic survey data and focusing plate convergent margin tectonics. After about 10 years service at the Geological Survey of Japan, I moved to the JAMSTEC and joined an organization of scientific ocean drilling which is managing the state-of-the-art scientific ocean drilling vessel “CHIKYU” in 2002. I’m continuing science services and management of international scientific ocean drilling program at JAMSTEC.
