Introduction of Research

I am involved in petrological, geochemical, experimental, and theoretical studies principally aimed at quantitative understanding generation, ascent, evolution, and eruption processes of magmas, differentiation processes of the lunar magma ocean, and evolutionary processes of the Earth.
