I am a Senior Scientist of the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) at Yokosuka, Japan. I graduated from the Hiroshima University (geology and geophysics) in 1998 and received the Ph.D. (in geophysics) from the Earthquake Research Institute (ERI), the University of Tokyo in 2003. My scientific interests cover studies of the mantle and core dynamics, earth's evolutionary history, seismotectonics, and computational fluid dynamics. I have been working as a visiting associate professor of the ERI in 2011. I have been awarded the SC2004 Gordon Bell Award of the Institute of Electrical and Electronics Engineers (IEEE) in 2004, the JAMSTEC R&D Achievement Award in 2013, the Scientific Image Award of The Visualization Society of Japan in 2014, and the Best Guest Editor Award of Geoscience Frontiers in 2016.
I am engaged in the researches on mantle dynamics and global tectonics with various geophysical approaches, in particular, numerical simulations, hydrodynamic theory analyses, and geophysical data analyses, in collaboration with seismologists, geologists, and geochemists. The aims of my study are to solve the thermal and compositional evolutions of the Earth's mantle and core, the onset conditions and mechanisms of plate tectonics, the behavior of subducted plates in the deep mantle, the driving forces of the supercontinental breakup and continental drift, and the tectonic and geological conditions of great earthquakes.
