Professor Scott Hudson a Professor at Carnegie Mellon got his BS and MS at ASU and Doctorate from Univ of Colorado, Boulder. Nenad Medvidovic a Professor at USC got his BS ASU, MS & PhD at UC Irvine. Can’t tell you if anyone went to Harvard, but unless they were researching the things that the Harvard professors research they wouldn’t have applied. Grad student that do not have aligned interests won’t be in the running. Harvard is very difficult to get admitted to for CS grad school. There aren’t a lot of openings and it is quite highly ranked anyway. FYI.
