Hi,
I agree with John, I have a few publications from my job, but I also managed to get one whilst doing a summer placement sponsored by the Wellcome Trust whilst at uni.
I think you will have oportunity to do this in the summer after your first year, providing you find a suitable supervisor to put forward a grant and research project for you. You could begin by getting in touch with the relevant department(s) now to see if they could help you in the future. It will do no harm asking, it only shows enthusiasm!
