Many students interested in biochemistry do independent research with faculty.  To get involved with research, you should contact a few faculty members you might be interested in working with to discuss projects in their labs.  If those faculty members are currently taking research students, they will likely set up a time to talk with you further about their research projects and your interests in research.  You can learn more about biochemistry research being done by faculty in a variety of departments on the Biochemistry Program website.
