Education

Molecular Microbiology and Immunology Programs
Master of Health Science (MHS)
The 9-month MHS program includes a core curriculum focused on the biology, immunology, and transmission dynamics of major infectious diseases related to public health.
Master of Science (ScM)
The 2-year ScM program gives students an understanding of infectious diseases guided by research experience in the laboratory or field.
Doctor of Philosophy (PhD)
The 5-year PhD program allows students to focus on the cellular and molecular mechanisms that drive infectious and immune diseases, the opportunity to take courses focused on a specific research area, and to benefit from lab rotations, mentored research, and professional development.
Centers and Institutes in the Department of Molecular Microbiology and Immunology
We host six centers and institutes that advance our research initiatives.
Johns Hopkins Malaria Research Institute
Johns Hopkins Center for Women's Health, Sex, and Gender Research
Johns Hopkins Center of Excellence for Influenza Research and Response (JH CEIRR)
Lyme and Tickborne Diseases Research and Education Institute
