What kind of scientist would Santa be?

I don't think he'd be a scientist. [Link]

So the premise is that Santa is at least several hundred years old, and you've got to assume that somewhere along the line, he spent some time in academia and probably got a degree or two. Now, I'm going to go out on a limb here and suggest that he is a man of science, but I guess the question to ask is in what way specifically?

I'm thinking Linux guy, Jon "maddog" Hall
