THAT...is something I would need to figure out, yes. In canon he's the archchancellor, which basically is the headmaster of a magical university. In this he's a bit lower ranked. He probably teaches several classes. History of Sanctuary, Responsible Use of Enlightened powers, Magical Theory...

Really though he tries to get out of actually lecturing whenever he can. His students need to show initiative and that means hunting him down before he leaves for the day to go fly fishing.
