Those who are interested in theatre studies may benefit from a program of study in this field. Topics covered might include everything from stage design to directing, as well as theatre, culture, and the impacts of theatre on society at large.

The PhD is a doctoral degree, specifically called a "doctor of philosophy" degree.

That said, PhD recipients are able to engage in thought experiments, reason about problems, and solve problems in sophisticated ways.
