Researcher's Profile

All the matter that makes up our bodies and our planet comes from stars that exploded in the space before the formation of our solar system.

Meteorites serve as time capsules, preserving the primordial materials created by these stars. In contrast, Earth's rocks record the evolution of solar system materials through planetary processes. By comprehensively comparing and analyzing the meteorites and the Earth's rocks, we can unravel the formation mechanism of the Earth and the Solar System over a period of 4.5 billion years. 

We are investigating the formation and evolution of the solar system by deciphering the information recorded in planetary materials. This is achieved through a combination of mineralogical analysis and isotopic analysis using mass spectrometry. We are also participate in international planetary exploration, and contribute to the future of space exploration in the field of planetary science.
