Welcome to the Tomohiro Usui Research Group! We are planetary scientists, geologists, and remote sensing experts.

The Usui lab spans the options in ISAS’s Department of Solar System Sciences.

As of December 2018, we are seeking new graduate students or postdocs. Candidates for the Department postdoctoral fellowship programs or ISAS graduate studies should consider applying, especially if research interests span multiple faculty. [Contact]
