We are sorry to hear that you are experiencing an issue with your supervisor.
If you have discussed this with them and you still need someone to step in, please contact staff in your faculty research office who will be able to discuss the situation with you and will help you to determine the best way forward. To find out who you could contact, please see page 10 of the Handbook.
We understand that this situation can be stressful; please remember that there is support available at the university.
