People associate professors generally with lab coat, though I think it's only when they're on the job (except Oak, who is on the job 24/7
and is probably based on the age of actual oak trees).
For me, any original professor would probably revolve around a reason/purpose for why they came into their profession in the first place. Their attitude/personality trait would probably leave occasional hints about their cause.
Of course, whatever activities they do in their research is up to you.
