Each staff member has their own laboratory and research students. Some staff have also formed research groups in the department or faculty, sharing key research instruments, holding joint seminar sessions or conducting collaborative fieldwork. Some staff also belong to research groups outside of the university, some of which are Japanese projects operating domestically or overseas (e.g. JARE), while others are truly international (e.g. IODP).
