Need some help thinking of who could examine you? Start with these six questions to get a list of names:
- Whose work have you built on in a meaningful way?
- Who have you met at conferences?
- Who has a good reputation?
- Who is an expert in your field?
- Who have you cited a few times?
- Who do you think you can trust to do a good job?
With these six questions you can get a long or short list quite quickly. Then you have to figure out how you narrow it down so that you can have a chat with your supervisors.
A more useful question perhaps: what are you really looking for in an examiner?
Once you know the answer to this, you can have a more meaningful conversation with your supervisors about who might be a good choice.
