Mizuho Koike

Thank you for visiting this website. I am a geo-cosmochemist. My research interest is origin & evolution of planetary surface system, especially (1) Mars: water and habitable history, (2) Asteroids: formation and collisions, and (3) early Earth environments.

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.

Here are Recent Research Highlights

• A new research project concerning "Martian nitrogen-cycle" has started since 2021FY (JSPS Grant-in-Aid for Sicentific Research (B) -21H01149)

• Early collisional history of the Solar System was retrieved from Vesta-group meteorites using U-Pb dating technique. [Koike et al. (2020b)] [プレスリリース(日本語)]

• We have found 4-billion-year-old nitrogen-containing organic molecules from a famous Martian meteorite, ALH 84001. [Koike et al. (2020a)] [EurekAlert!] [ELSI research highlights] [MMX News (En) (日本語)] [academist Journal 研究コラム (日本語) ]

• (Collaboration work) Scientific importance of Martian Moons sample return [Usui et al. (including Koike)(2020) ]
