I turned down the university's acceptance in order to find a program whose professors I more closely identify with.
In the above sentence, it is difficult to figure our whether "with" is being used as part of a phrasal verb or a preposition. I know it is not best practice to end a sentence in prepositions, but even if this "with" is not a preposition, it makes the sentence seem strange.
Also, I chose "whose" because it sounds even worse to say:
I turned down the university's acceptance in order to find a program with professors I more closely identify with.
And in this last example it wouldn't sound right to just leave off the last "with."
