Sorry I'm late getting back into the game here. Aviation medicine has to do with medical certification of pilots and related issues (like, aeromedical evacuation). You can't swing a cat in Alaska without hitting 3 pilots, so there is plenty to do. Most of us doing this are also pilots, and do it for the fun of it; we get paid a modest sum for spending half an hour talking about flying with fascinating people who are desperate to stay healthy. It is very cool. It is actually a subfield of occupational medicine, and we have a real journal "Aviation, Space, and Environmental Medicine" that publishes such pithy topics as "The Effects of +Gz Acceleration on the Circadian Cortisol Levels in Anesthetized Rats."
