What specific area? You need to find a potential supervisor to begin with. Then narrow down to the knowledge domain that you'd want to pursue.

PhD no class. It's pure research.

If you want a "mix-mode" type for doctoral level, you can look up at DBA (Doctor of Business Administration) or EdD (Doctor of Education).

If you have to attend classes, do assignments, and the final component is a thesis. Some DBAs even require you to do real-life consultation.

I think you have to find that out yourself because I don't know the courses offered by each individual university.

there is no short cut to find the info that only you yourself know what you want.
Especially you are talking about PhD research degree.
re-search means search and search...
