Organising a supervisor
The role of supervisors is to advise, guide and provide constructive feedback to you through the processes of choosing a realistic topic, designing a viable project, doing the research and interpreting the findings and writing the dissertation.
Most graduate research students are supervised by two or more members of staff. External supervisors are welcome additions.
Generally, allocation of supervisors is a matter for individual negotiation between student and supervisor, and students are free to choose.
Make your choice with great care, as the effectiveness of the student/supervisor relationship has a major effect on your experience.
