Mungo, I'm guessing you're in

grad school. If you're not, dang you have a great educational system! The "tutor" system is used in the USA at MA

and PhD levels, but we call them advisors, e.g., a professor that oversees your area speciality. The term tutor is

commonly used for student teachers that help other students having academic difficulty. For example, star football

players have tutors because they're usually a bit slow upstairs.
