OMG!!!!!!!!!! I'm screwed. I'm currently doing a master at Yale and in my application to UPenn, I mentioned I'd be interested to work with Kao. How could I not know that??!!!!!!
That's about the size.
Not really actually.... in 2015 there're only two new students. But yeah, a quite famous professor from the department who wrote me a reference letter told me that since many professors were on leave, they needed to limit the size. Also, the department enrolled about ten students last fall. Bad news for us. Really tough time this year. The professor explicitly told me to apply to as many programs as possible and she'd be happy to upload the letter for my multiple times. So I figured my chance's slim.
