Registration for the 2023 Perlman Symposium is open! This year’s Symposium will be taking place on Friday, June 2, 2023 and is free for attendees!


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 the Department of Medical Microbiology & Immunology’s establishment in 1935, we have made fundamental contributions to the study of infectious disease and immunity. Our current faculty are well-established, recognized leaders in the field.

Research underway in our department involves bacterial, fungal, protozoan, and viral pathogens. Organisms under study are: Toxoplasma gondii, Neisseria gonorrhoeae, Mycobacterium sp., Brucellasp., Listeria, Blastomyces, Aspergillus, Cryptococcus neoformans, Candida, influenza virus, Herpes simplex, and uropathogenic Escherichia coli. Faculty also investigate diverse immunological topics such as the sexual dimorphism of immune responses, regulatory T cell biology, leukocyte migration, and vaccine development.

We  provide an exceptional learning environment for undergraduates through rigorous coursework and research opportunities. Graduate students may earn a Ph.D. through our nationally acclaimed, Microbiology Doctoral Training Program which is ranked first among U.S. public institutions and third nationwide.

Caitlin Pepperell, PhD

“Science is hard work and challenging in myriad ways, but at its essence it should be a joyful pursuit. Look for mentors, opportunities and environments that make you excited about the pursuit of new knowledge.”

Meet Caitlin!


Throughout the academic year, the Department of Medical Microbiology & Immunology hosts several seminars covering a range of immunological topics.


Diversity is a source of strength, creativity, and innovation for UW–Madison. We value the contributions of each person and respect the profound ways their identity, culture, background, experience, status, and abilities enrich the university.
