UK , I met him at an engineering conference but it was 15 years ago now. BUt I suspect he is abroad now working for surgicraft or the like.
The bio-engineering units sometimes have a medical-physics attached or they are attached to or they don't. Some have quite a large cross discipline groups from Medics right through to software engineers, or they are just a load of engineers depending where there focus is.
I wouldn't be suprised if you could find something that would allow you to combine the vision stuff with engineering. For example the robotics for nuclear decomissioning etc.
Its one of the good things about engineering if you enjoy it. You can get something between Finance and law right the way through to flying planes or high energy physics experiments.
