How long can you leave it to ask for feedback from an interview? I was at one at end of May so I e-mailed potential supervisor to get feedback but he didn't reply as he was moving unis. I think he has only recently been added onto staff list of new uni so is it still ok to email when the account gets set up? Or has the gap been too long and will look funny if I ask for feedback now? Please help. Thanks.

It's worth emailing to ask. The supervisor can always choose not to reply.
