Congrats! Are you accepting the offer? Where else did you apply?
From what I can tell, I’m a fan. I’ve had the inverse experience in that I applied specifically to work with a few POIs. I did their summer MICHHERS program which gave me a lot of insights into faculty, interests, and departmental priorities. I’d encourage you to reach out to grad students in the program if you haven’t already. The folks I’ve spoken with have been excellent and have offered really great insights into the realities of the experience.
