I may quit my current PhD position after a year and a half due to supervision-related reasons. My promotor is the professor who is head of team (and supervised my master thesis), while I am currently supervised by another academic. My promotor is a very kind and considerate person. I have looked up another PhD position in a different country that suites my interests best. How to ask him for a letter of recommendation for the new PhD position?
I don't have any publications yet. My current promotor is currently evaluating a paper I wrote from my master thesis. I may also write another one from my master thesis. I would like to continue my work on these papers with him - how do I approach this situation without affecting the review process by him?
