This Wikipedia page says that the Black Panther, T'Challa, is a trained scientist who also invented the Quinjet. The same article says that he studied abroad. He clearly has advanced engineering skills.
Where did T'Challa go to school?
T'Challa Black Panther went to graduate school at Oxford University in England and received a PhD in Physics. That's from this Wikia article, citing the Official Handbook of the Marvel Universe A-Z Vol 1:1.
He gained a Ph.D. in Physics from Oxford University.
The official wiki lists "Ph.D in physics" under "Education," but does not name a location.
