Department of Molecular Microbiology
and Immunology

As the oldest and largest school of its kind, the Johns Hopkins Bloomberg School of Public Health brings together leading public health professionals to investigate and provide solutions to health issues of populations around the world.

The Department of Molecular Microbiology and Immunology has more than 20 active faculty members conducting research in the laboratory, in the clinic and in the field. In addition, many faculty from other departments in the School and the Johns Hopkins University School of Medicine collaborate with MMI faculty, teach and mentor MMI students. 

Departmental research interests are wide by design, and include: virology, bacteriology, parasitology, medical entomology, immunology, ecology of infectious diseases and many topics relevant to the emergence of new infectious diseases. The premise of this broad approach is that public health problems are best addressed by understanding their underlying biological mechanisms. This approach is also reflected in the degree programs offered by MMI.
