It means "At university, she studied biology.", correct?
So far I've learned that location goes after the subject, but I've seen this construct twice now. The other time it was in a sentence that was translated (not by me) to "We are not allowed to eat inside the subway".
The "inside the subway" bit was again at the front of the sentence. It's not really any harder for me to read, but if I was asked write this sentence I'd probably forget and put the location after the subject.
Why does the 在...里 construct lead?
