The PhD degree in the Global Environmental Health Sciences Department is an advanced research degree that prepares students to employ laboratory and community approaches to address adverse environmental health impacts. Students use basic and applied research methodologies to examine consequences of chemical and non-chemical stressors and disasters. Graduates of the PhD programs advance to careers at academic institutions, governmental agencies, industry and nonprofit organizations.
- Design original environmental health research.
- Collect data to address environmental health problems.
- Analyze environmental health data.
- Make recommendations based on environmental health data.
- Communicate environmental health research findings.
The PhD program requires a minimum of 72 post-baccalaureate degree credits, with at least 30 credits of doctoral study at Tulane SPHTM. Up to 42 credits may be applied from the MPH or equivalent master’s degree. Upon admission to the PhD program, faculty review the master’s degree coursework to determine credits that may be applied toward the PhD degree. If a prerequisite course or equivalent has not been fulfilled, the student must take the course in addition to the 30 credits of advanced doctoral study, but may count toward the total 72 credits. All students in SPHTM without prior public health degrees are also required to take SPHL 6020 Foundations in Public Health (3 c.h.) that provides an overview of public health. [link to PhD Handbook]
The PhD must be completed within seven years of matriculation into the doctoral program.

Electives selected from relevant advanced courses offered within the department, school, or university in consultation with an academic advisor. Additional credits may be needed to obtain a total of 72 credits. No more than 12 credits of special (independent) studies may be applied toward the doctoral degree.
Students are required to take online research ethics training via CITI or another equivalent training program in research ethics. This certification must remain current throughout the program duration.
The departmental faculty administer the comprehensive examination. The exam should be taken no later than a year after completing all required coursework. The comprehensive exam is offered in January, August, or by special arrangement. The exam consists of written questions from the faculty that gauge the student’s ability to identify, assess, and propose approaches to study environmental health problems.
Students have two attempts to pass the examination; the second attempt must take place within a year of the first. (Link to GEHS PhD guidance)
After successful completion of the comprehensive examination, the student forms a dissertation committee and develops a prospectus. The committee must include a minimum of three members with at least two faculty from the Department of Global Environmental Health Sciences and one external to the school.
Students work with their advisor and doctoral committee to determine a research hypothesis and prepare a prospectus of proposed dissertation research. The research prospectus is presented and defended at least one semester before the dissertation defense. Following the successful defense of the prospectus, students are admitted to PhD candidacy and proceed with dissertation research.
Students must conduct original research and defend a dissertation based on that research. The dissertation research demonstrates scholarly work and is the basis for the dissertation. The student defends the dissertation to their committee; the dissertation committee and SPHTM Executive Faculty approve the dissertation.
