Please feel free to correct the title, I am not sure how to formulate this crisp & clear in a sentence.
I am very interested in a particular graduate program. It's a top notch program, but I happen to want to work with an academic who is quite young still and not yet a professor, and although the program is o.k. for the subfield I am interested in, it is not stellar. (Let's not discuss here whether this would be a clever move please)
Question: Will it affect my chances getting into the program, that is, would a university rather see students interested in the field they are already strong in, or would they like to see someone being interested in something for which the uni is not particularly known for?
Will the prospective advisor maybe have less of a say regarding my admission, than if I were to target a senior professor who would like to work with me?
