The Ph.D. is offered, according to subject-area, in Archaeology or in Conservation Studies. A Ph.D. should normally be completed within three years from the start of enrolment. Thus research projects should, at the outset, be designed to be capable of completion (including submission of the thesis) within that time, and the timetable for the conduct of research should reflect this: although the Regulations make provision for an additional year for the submission of the thesis, students should not embark on the Ph.D. program expecting to avail themselves of this.
