If that Prof. is Yang Yi, you better think twice. This guy has a bad record in placing his students and his mentality toward placing or mentoring his students is awful, fearing that he or she would surpass him. Sound hilarious but that happens. Avoid him at all cost. On a side note, if you are not from PKU/Tsinghua/CUST/Fudan/perhaps Nankai or Zhejiang U, you can forget about top programs in the States. That manuscript, even being accepted, will not enhance your background too much.

Given your intention to find a placement in industry and to collaborate with CS department, I would definitely suggest to go for Columbia. Columbia has a better CS department and hey, New York is an ideal city to find a job, given your Columbia degree.
