Division of Earth and Planetary Materials Science (Doctor's Course)

Department of Analytical Planetary Chemistry

The goal of our research is to understand comprehensively the origin, evolution, and the dynamics of the Earth and the Solar system using geochemical tracers and chronometers. To achieve this, we quantitatively examine elementary physicochemical processes such as elemental transport, re-distribution, and isotopic fractionation related to natural phenomena by applying state-of-the-art analytical techniques. Additionally, the targets of our pursuits are not limited to the earth sciences; we are investigating broader scientific fields such as biochemistry and the medical sciences.

Department of Experimental Planetary Physics

We study physical and chemical properties of the Earth's constituents, particularly at high pressures and high temperatures. Combining these knowledge with geophysical and geochemical observations, we obtain better understanding of the dynamics and evolution of the Earth and other terrestrial planets.
