Depends on what type of project you want to do. Retrospective and case study is easy and can basically be done whenever you want, just have to have access to charts which means you need to be friendly with a PM&R doc.
Approach your faculty and tell them you're interested and see if they have anything going that you can help out on. Or try to come up with a couple easy projects and offer them as ideas and see if anyone bites to supervise/co-author with you (especially if your school has a residency program where you can try to get involved with a resident).
