Thanks. Don't count much on UNC INSTORE, as a professor told me that they would accept VERY FEW (aka, 1 - 3, I guess?) students this year while receiving a HUGE number of applications. I think you would have a better shot at NYU DS (I also plan to apply there for the MS program, as I just knew about the PhD program after the deadline...Too bad for me:p) and Stanford ICME (missed the deadline. Same story with Ross Business School:P), which are even better in terms of brand's reputation, and the professors there.
