Cool thanks. Any more advice?
If you have a PI, get to know him or her well - they could be a great mentor and possibly write a recommendation down the line. If it's a physician, make sure to spend a few days with them clinically if you're interested in the field and haven't seen it before. They can also give you an idea of the hot topics in the field, which may help you come up with some questions on your own. And no shame if you don't - it's difficult when you're not familiar with the literature.
Learn the research procedures at your institution - are you doing clinical, bench or animal work? Make sure you're squared away with the appropriate research board before you get working, hopefully there is some sort of orientation for that, and you may have some training to do before you can actually start working.
A lot of what you're doing will be done independently, so make sure to update them on where you are with your project. You'll be able to gauge how frequently this should be. To give you an idea, I've been updating about once a week while I'm slogging through data and it'll be more frequent once our databases are established and we're actually working on the statistics and writing up the results.
The biggest thing though, and this should go without saying, is to be professional. Show up when you're expected to, dress according to the lab/clinic standards, etc. Basically, go with the flow of your institution and be nice to everyone - you'll never know where help can come from when you have a question. Professionalism goes a long way. (Hopefully I'm just preaching to the choir, as I don't know your work history.)
