The Doctor of Philosophy (PhD) degree programs at St. George’s University are offered through the Schools of Medicine, Veterinary Medicine, and Arts and Sciences and require a total of 60 credits or more. All PhD programs require the production and defense of a doctoral thesis. Transfer credits are accepted from approved institutions and the candidate’s supervisory committee determines the number of credits that may be incorporated, following specified guidelines. Research and coursework are directed by the candidate’s supervisory committee. All completed theses, upon the recommendation of the chair of the supervisory committee, are submitted to the Dean of the School of Graduate Studies and forwarded to an external examiner. A final oral presentation and defense of the thesis must be successfully completed prior to being awarded the degree.
