Stanford is also heading in that direction I think, they recently hired Drew Endy and Christina Smolke. I haven't heard from JHU or Berkeley-UCSF joint grad program yet. If you look at http://thegradcafe.com/survey/index.php someone already submitted that they got an interview from Berkeley and another that he called the department and was informed that all interview invitations were sent. Well...not a good sign, but we'll see.
My interview for SD bioengineering is Feb 6th, I assume they're doing all the interviews at once, so anyone who is waiting for UCSD should probably expect a response within the next week.
