A doctor was one of the highest degrees that could be awarded by a university to a person in their discipline. This title may refer to a Doctor of Medicine (MD) or a Doctor of Philosophy (PhD) for scientific pursuits. Doctors who serve in Starfleet are generally referred to by their title of "doctor" instead of "sir" or their rank, by both lower-ranking personnel and superior officers.
