Is my acceptance into the MA program or Ph.D. program contingent upon working with a specific professor or research mentor?
No. You are free to choose the mentor you wish to work with once you are admitted to the program. Although it is not required for you to choose a mentor before you join the program, it is beneficial to be very clear about your research interests and have a few potential mentors in mind. This will help determine whether you are a good match for the program. Additionally, in some cases, offers of funding are tied to a specific mentor and research laboratory.
