[Marvel] What is Dr. Doom's PhD in?
gpt
Surprising that with 11 comments there isn't a real answer yet.  Dr. Doom doesn't have a PhD.  He was in school for theoretical physics but he was expelled after a machine he'd built exploded (due to Ben Grimm's sabotage).  After he left he just gave himself the title of doctor and no one really disputes it because he IS a genius and far more intelligent than a single degree would account for.
