I'd use for/in the field. However, I can't see much point in using the sentence if this is still for a CV. If you're applying for a job in this field, then it is likely that the person will know that it's a good university, so telling them in this way could come across as patronising or even a bit pushy. Simply the name of a good university should suffice, though other people may feel differently.
