Yeah Scripts is a good place to go. have a look around as different institutions specialise in certain areas.
Well best thing to do is to try and work with people doing that sort of research at the institution you go to. So you should be able to find faculty and their specialities and research interests. For example here are the people at Scripts who do the work on that.

If you go there on Day 1 after all the introduction and stuff. Talk to them about your interest and enquire if they need undergrad help on any projects ongoing or in the future. PhD's often need help in the lab ect.
But don't limit yourself to one thing, go to a few people who's work you are interested in and ask if they need help.
Eg when I did my undergrad I helped with Diving surveys, lobster culture, jellyfish culture, evolution and climate change experiments, fish nutrition trials, environmental surveys, public outreach. As well as so many lab techniques.
Try and get a wide base of experience which you can build on in the future.
