About the PhD in Environmental Health Program

The Doctor of Philosophy (PhD) degree program is a full-time degree program that offers a unique interdisciplinary learning experience where the course of study is individually tailored based on the student’s interest in understanding and finding solutions to pressing problems in environmental health and engineering.

The goal of PhD training in EHE is to prepare graduates to engage in scholarship and professional practice that creates new knowledge, use research to transform practice and improve the health of the environment and the public, and effectively communicate research findings to the public. The program requires didactic coursework followed by an average of four to five years of research towards a doctoral dissertation (also referred to as a thesis on official forms and committees).

Training is offered through a core curriculum that is required of all PhD students in the Department with the addition of track/program-specific requirements and focused courses in specialized areas.

Students are expected to tailor their curricula, working with their advisers to create a comprehensive plan of study and research. PhD thesis must be based on original research, worthy of publication, and approved by the Department and a committee of thesis (dissertation) readers. PhD students must also be engaged in primary data collection as a component of their dissertation research or embedded in other research during their training here.

Our programs are offered in the Whiting School of Engineering, on the Homewood campus (WSE) and the Bloomberg School of Public Health (BSPH) East Baltimore campus. Students in all of our programs have the unique opportunity to take classes on both the Homewood and East Baltimore campuses in order to complete their degree requirements.

Students in the PhD in Environmental Health program select from one of four tracks:

Vivien Thomas PhD Scholars

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, 2023.

Need-Based Relocation Grants
Students who are admitted to PhD programs at JHU starting in Fall 2023 or beyond can apply to receive a $1500 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.
