The mission of the Department of Medical Microbiology & Immunology is to provide comprehensive scientific instruction to students, conduct meaningful research, and offer consultation and service in microbiology and immunology as they relate to human health and disease.
Who We Are
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, our labs study the roles of diet, the immune system and the gut-brain-axis in the intestinal microbiome. The Department of Medical Microbiology & Immunology is housed under the School of Medicine and Public Health.

Meet Our Researchers
Christina Hull, PhD
“Don’t worry about what or how everyone else is doing – focus on your interests and your goals and how to achieve them.”
Shai Bel, PhD
“Remember that science is like looking for a black cat in a dark room. This means that your advisor is fumbling in that dark room just like you are. They don’t have flashlight either. The only difference between you is that your advisor’s eyes have become a little more accustomed to the dark.”
Gustavo Caballero-Flores, PhD
“Since my very first biology classes until now, I have always been intrigued by the microscopic organisms present in our body, and all around us, and how we interact with them every day without realizing it.”
