Biography

Dr. Brewer completed a post-doctoral fellowship in cell biology at St. Jude Children’s Research Hospital. Dr. Brewer came to LUCOM with over 10 years of faculty experience in medical and graduate education in biomedical sciences, teaching immunology and mentoring students in the laboratory.

Dr. Brewer served on the faculty at the Stritch School of Medicine, Loyola University, Chicago, for 8 years and then at the University of South Alabama College of Medicine for 6 years. His research focuses on a cellular stress response mechanism, termed the unfolded protein response, and on the function of B-lymphocytes in the immune system.
