A doctoral advisor (also dissertation director or dissertation advisor, and known in British English as a doctoral supervisor) is an advanced member of a university faculty whose role is to guide a graduate student who is a candidate for a doctorate degree, helping them select coursework, as well as shaping, refining and directing the students' choice of sub-discipline in which they will be examined and/or on which they will write a dissertation.. Students generally choose advisors based on their areas of interest within their discipline, their desire to work closely with particular graduate faculty, and the willingness and availability of those faculty to work with them.
