What We Do in the Department of Molecular Microbiology and Immunology

The mission of MMI is to advance fundamental knowledge of human pathogens, host-microbe interactions and arthropod vectors, develop interventions to improve public health, and train scientists to conduct rigorous, ethical research while embracing diversity, inclusion and the unique experiences of all department members.  

We believe in the power of scientific discovery. Our diverse research programs and committed faculty offer students unparalleled opportunities in the laboratory, in the clinic, and in the field.

Molecular Microbiology and Immunology Programs

Master of Health Science (MHS)

Onsite | Full-Time | 9 months

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)

Onsite | Full-Time | 2 years

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)

Onsite | Full-Time | 5 years

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.

How do you study the world’s most dangerous animal? In a world-class, carefully designed facility. The Johns Hopkins Malaria Research Institute at the Bloomberg School is home to a 3,000-square-foot insectary, one of the largest in the U.S.

Core Facilities

Our faculty and collaborators work in state-of-the-art facilities tailored to specific research needs.
