Microbiology and Immunology

The Microbiology and Immunology Department is a community of biologists, virologists and immunologists focused on the study of the host’s interaction with foreign genomes along with inflammatory and autoimmune disorders. Researchers regularly explore the three main causes of death from infectious disease: HIV, malaria and tuberculosis. The department has a global perspective, with joint appointees conducting clinical trials in Haiti and Africa and forming international partnerships. Postdoctoral fellows, graduate students and medical students can take advantage of one of seven graduate tracks, including the Program in Immunology and Microbial Pathogenesis.
