It seems to be just the nickname he had on Gallifrey. If he has any sort of academic qualifications, he got it there, not a PhD on earth. Regardless, I'm certain there was an episode where he mentioned that he had medical training.

If I recall from the old series, his specialty was some sort of physics... the Rani kidnapped him for it or something.
