Personally I can't imagine what research he did when the actual outcome seemed to be so bad.
Not sure what he wanted out of life.

I can empathize a little with any difficult situations he may have encountered, but I would have thought he'd at least have made some short visits to validate or modify his research.
We all have our first time experience leaving our home country into a new country and new culture. This guy was probably totally unprepared for anything outside his daily routine with no-one to guide and mentor him.
Foolhardy.
