The Department of Medical Microbiology, Immunology and Cell Biology (MMICB) is dedicated to discovery-based, cutting-edge research that contribute to innovative advances in the diagnosis, treatment, and prevention of medical diseases. Our faculty are involved in discovery-based biomedical research and are dedicated to the education of graduate and medical students at SIU School of Medicine. 

Our innovative research is investigating clinically-significant fields such as:  mechanisms promoting tumor growth and metastasis, viral and bacterial pathogenesis, effects of microbiome on human physiology, and the role of the immune system in infections, cancer and reproduction. We also offer the the Public Health Laboratory Sciences (PHLS) program, which consists of graduate level classroom instruction augmented with extensive public health laboratory training.
