The character is Dr Nigel Bernard, it was a fairly small supporting role, he shows up in the panel where they're evaluating Paul Gross after he gets back to Canada, I couldn't see him in any of the trailers to pull a screencap.

Dude's biggest acting role was probably as sherriff Logan in the Pinkertons which only ran for a season, though he's shown up over the years here and there in a bunch of random different stuff. Like, he was credited in X-Men as "Cop #2" or something.

He was also a legitimately good teacher.
