It is essential that you identify and contact a potential supervisor as early as possible and no later than 2 months before you intend to make your application.
This is to ensure that they are interested in, available and appropriate to supervise your project, to give you adequate time to jointly develop a research proposal, and for them to agree to become your supervisor(s). They will also be able to help identify a second and sometimes third supervisor whose expertise would be of benefit to the project.
Applications submitted without a named supervisor/s and supervisory input to the research proposal will be at a severe disadvantage. A list of current staff and their research interests can be found here: Staff Research Interests - Durham University
