We encourage students interested in research to contact faculty directly. Send them an email or drop by their office. You can learn about each person's research area by looking at their personal page or lab page.
You can view the list of all our department faculty. If you click on a person's name you will eventually reach their personal page with all their research interests. If you think you might be interested in doing research in those topics then contact that person.
You can also view the list of all our research labs which are usually formed by a few faculty and their graduate students around a general research area.
Finally, USC has the Magellan Scholar Award for undergraduates. You can work your faculty research advisor to write a submission and perhaps win an award. This department has several Magellan winners every semester.
