The mission of the Department of Medical Microbiology & Immunology is to provide comprehensive scientific instruction to students, conduct novel and meaningful research, and offer consultation and service in microbiology and immunology as they relate to human health and disease.

Since its founding in 1935, the Department of Medical Microbiology & Immunology has significantly advanced the study of infectious diseases and immunity. Our renowned faculty lead research on bacterial, fungal, protozoan, and viral pathogens such as Toxoplasma gondii, Neisseria gonorrhoeae, Mycobacterium sp., Brucella sp., Listeria, Blastomyces, Aspergillus, Cryptococcus neoformans, Candida, influenza virus, Herpes simplex, enterohemorrhagic E. coli, and uropathogenic Escherichia coli. They also explore immunological topics including regulatory T cell biology, leukocyte migration and vaccine development. Additionally, the department study the roles of diet, the immune system and the gut-brain-axis in the intestinal microbiome.

We offer undergraduates rigorous coursework and research opportunities, and our nationally acclaimed Microbiology Doctoral Training Program allows graduate students to earn a Ph.D.
