PhD Discussion Forum

Hi, I am from a maths/physics background currently doing a PhD in fluid mechanics within the engineering department. I am not enjoying it as much as I'd liked and have raised this with my supervisor (only just, I am not sure what the outcome will be yet), and having done a little research into possible connected directions I can take it, I feel as though one of them would involve co-supervising with someone in the mathematic department, and one, if possible, by someone who is at a different university- but was at my university for around ten years, leaving around five years ago, and seems to be the only person who has worked in this area (it seems pretty niche worldwide relative to other areas) with connections to my university. Is the latter heard of for co-supervision or is it a very long-shot? many thanks in advance

hey thanks alot for your reply, that's helpful :) re. on the last sentence yes ofc I thought so. On the previous sentence- this is another thing I am considering- who do I approach first here? my own supervisor having identified someone I would want to work with, or the potential co-supervisor first. the former seems silly if the potential co-supervisor would not be willing to work with us, and the latter seems rude, as though I should check with my own supervisor first. Many thanks :)
