Admission officers may be able to tell you about research opportunities that are available on a campus you are considering. Also, your campus may have an office of undergraduate research. If so, that may be the best place to look once you have matriculated as a student.
Participation in research enriches students' learning experiences, provides improved preparation for graduate school or work, and creates involved citizens who address community problems. The opportunities are countless, and students who seek out such experiences will be rewarded with both engaging work and increased career options.
