I will be enrolling in a Master's program for Biomedical Informatics next fall.
I already know the faculty member that I would like to be mentored by (working as a student intern with one of his graduate students). However, I was told that I will most likely be assigned another mentor upon starting the program.
Would it be best to work under a new faculty member while under MS program and attempt to transition into PhD later and talk with the professor that I would like as my mentor? Or would it be best to talk to the professor before starting the MS program about possibly having him as my mentor in the first place?
P.S. Also, what is the best way of approaching a professor about receiving support as in funding?
