Howard SOC Students..Help

There is a teacher there by the name of Sherrie Wallington who teaches Communications Research (At Bowie, the course is COMM 430). Has anyone had her? I ask this because I'm having difficulty with my topic. It deals with advertising and consumers. Do you know of any e-Journals which might be useful? Or any general tips when it comes to this professor? I just asked because she teaches in the exact format at both schools.
