About the PhD in Molecular Microbiology and Immunology Program
Through a departmental core curriculum as well as research area-specific courses, laboratory rotations, qualifying examinations, mentored research, and professional development, all MMI PhD students are prepared to engage in cutting edge research and scholarship that advances knowledge.
MMI PhD students hone their scholarship, research and professional skills. Course and laboratory work can address problems in microbial pathogenesis, immunology, disease transmission, and diseases related to malaria, mosquito and arboviral biology.
Students can choose to complete the traditional MMI PhD program or the MMI PhD program concentration in Rigorous, Reproducible, and Responsible Research Investigation in Immunology & Microbiology (R3IM).
The concentration in Rigorous, Reproducible, and Responsible Research Investigation in Immunology & Microbiology (R3IM) conveys a broad background in immunology and infectious diseases research, with a special emphasis on critical thinking, logic, ethics, and written and oral skills to help graduates become communicators of complex scientific concepts and agents of change in their workplaces and communities.

Admissions Requirements
For general admissions requirements, please visit the How to Apply page.
Standardized Test Scores
Standardized test scores (GRE) are optional for this program. The admissions committee will make no assumptions if a standardized test score is omitted from an application, but will require evidence of quantitative/analytical ability through other application components such as academic transcripts and/or supplemental questions. Applications will be reviewed holistically based on all application components.
Vivian Thomas Scholars Initiative
The Vivien Thomas Scholars Initiative (VTSI) is an endowed fellowship program at Johns Hopkins for PhD students in STEM fields. It provides full tuition, stipend, and benefits while also providing targeted mentoring, networking, community, and professional development opportunities. Students who have attended a historically Black college and university (HBCU) or other minority serving institution (MSI) for undergraduate study are eligible to apply. To be considered for the VTSI, you will need to submit a SOPHAS application, VTSI supplementary materials, and all supporting documents (letters, transcripts, and test scores) by December 1, 2024. VTSI applicants are eligible for an application fee waiver, but the fee waiver must be requested by November 15, 2024 and prior to submission of the SOPHAS application.


Tuition and Funding
Per the Collective Bargaining Agreement (CBA) with the JHU PhD Union, the minimum guaranteed 2025-2026 academic year stipend is $50,000 for all PhD students with a 4% increase the following year. Tuition, fees, and medical benefits are provided, including health insurance premiums for PhD student’s children and spouses of international students, depending on visa type. The minimum stipend and tuition coverage is guaranteed for at least the first four years of a BSPH PhD program; specific amounts and the number of years supported, as well as work expectations related to that stipend will vary across departments and funding source. Please refer to the CBA to review specific benefits, compensation, and other terms
Need-Based Relocation Grants
Students who are admitted to PhD programs at JHU starting in Fall 2023 or beyond can apply to receive a need-based grant to offset the costs of relocating to be able to attend JHU. These grants provide funding to a portion of incoming students who, without this money, may otherwise not be able to afford to relocate to JHU for their PhD program. This is not a merit-based grant. Applications will be evaluated solely based on financial need. View more information about the need-based relocation grants for PhD students.
