Nationality doesn't bother me, but I do sometimes wonder about the quality of universities in other countries. Honestly, if the Mayo Clinic(where he used to work) and Vandy think his credentials are good enough, I'll go with that. I just was curious about what would be said about the quality of the education at Baghdad University. Didn't really find anything on that, but when I read the wiki on it, that stood out. Honestly, I just started laughing. Wiki being open like it is, I'm sure the university had no control, but I'm fairly certain they wouldn't want the person listed as one of their "notable" alumnus.
