I am wondering this as well. I have a Skype interview for a program on Thursday and they told me today which two professors will be doing my interview. Neither of them are even from the DEPARTMENTS I am interested in. It's an interdisciplinary program. My interests on application are biochemistry/molecular biology, cancer biology, personalized medicine, and stem cell biology. The professors are from Pharmacology, Toxicology, and Therapeutics (ok I can see how that is minimally relevant but his research is not), and then Anatomy and Cell Biology. So kind of have no clue what to expect.
