Ask former PhD supervisor advice I did my PhD on topic X, and my PhD advisor is an expert on X and on Y. For a problem I have come across in my postdoc, I think that Y would be a good approach. There is no one I am currently working with that I could ask about Y, so I would like to send my PhD advisor an email asking for literature recommendations on topic Y. Is this customary? What would be the most polite way to ask? What is the best way to go about this?

Don't overthink this: Just email your advisor, it is normal.
