The supervisor-candidate relationship can be one of the most rewarding aspects of academic life for both supervisor and candidate. There is no single right way to supervise or to complete a PhD or MPhil thesis and the supervision relationship will usually change over time as the needs of the candidate and project change. There are, however, some hallmarks of most successful supervision relationships including: good communication; agreed standards; professionalism; consideration of the needs of the other party, and ethical behaviour.
The University has rules for supervision and PhD and MPhil candidature. These rules prevail over any of the comments made here. In particular, see the Graduate Research Training Policy (MPF1321) and the Supervisor Eligibility and Registration Policy (MPF1322). Guidelines for students and supervisors can be found at the working with my supervisors and the expectation of supervisors sections on the Graduate Research Hub webpage.
