About Myself
My research interests focus on the evolutional history of Earth-related planets and small bodies (e.g., asteroids), as well as their potential habitability. As a cosmo-geochemist, I have been studying chemical and isotopic records in extraterrestrial materials by using high-spatial resolution analytical techniques. My main targets are meteorites that originated from [I] Mars and [II] a large rocky asteroid 4–Vesta.
In technical aspect, I mainly use secondary ion mass spectrometry (SIMS), X-ray Absorption Fine Structure (XAFS), SEM, EPMA, FIB, and noble gas mass spectrometry.
Outline of my research topics is introduced in Research Topics page.
My research achievements are summarized in Publications page.
[new] A recent work on a unique and interesting meteorite, NWA 16895, is introduced here.
