The science department websites may have synopses of research interests. If not, talk with individual professors and ask them about their research and about what other professors in their department are researching.
First, eliminate the research that sounds boring to you, or that you don't really want to do.
Second, choose who you research based on (1) whether there is an immediate opening in their lab (vs. waiting a semester to get in) and (2) how you think you'd work with the prof. and how much you'd be able to get out of their mentoring.
You have to find something that is interesting and that you'll get a lot out of.
