2006年より、JAXA宇宙科学研究所に所属。それまでの宇宙プラズマ物理の研究に加え、太陽系探査の企画推進にも関わるように。その立場で貢献してきたものとして、JUICE, ひさき、ERG、はやぶさ2,MMX、DESTINY+。宇宙プラズマ研究において多体系の物理への興味が高かったこと、JAXAが得意とする小天体とのリンクが強いことから、N体計算からの惑星系形成論も研究テーマに追加した。また、太陽系探査以外の宇宙科学計画の国際協力調整にも携わる。

Sep 7, 2018The surface of the Martian moon Phobos exhibits two distinct geologic units, known as the red and blue units. The provenance of these regions is uncertain yet crucial to understanding the origin of the Martian moon and its interaction with the space environment. Here we show that Phobos' orbital eccentricity can cause sufficient grain motion to refresh its surface, suggesting that space weathering is the likely driver of the dichotomy on the moon's surface. In particular, we predict that blue regions are made up of pristine endogenic material that can be uncovered in steep terrain subject to large variations in the tidal forcing from Mars. The predictions of our model are consistent with current spacecraft observations which show that blue units are found near these regions.
