PhD in Global Environmental Health Sciences

• 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.

Applicants must meet the school's admission requirements for entrance into doctoral programs.

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 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.

Prerequisite Coursework (from prior master's degree)

Students who do not have these prerequisites are required to take these or equivalent courses.

• GEHS 6030 Survey of Environmental Health (or equivalent)
• GEHS 6600 Principles of Toxicology (or equivalent)
• SPHL 6020 Foundations of Public Health (or equivalent)
• SPHL 6050 Biostatistics for Public Health (or equivalent)
• SPHL 6060 Epidemiology for Public Health (or equivalent)

Required Courses (at least 10 credits)

• BIOS 6040 Intermediate Biostatistics (3)
• EPID 7120 Epidemiologic Methods II (3)
• SPHL 8500 Interdisciplinary Doctoral Seminar (1)
• GEHS 7270 Epidemiological Applications of Env Health Sciences Research (3)

Elective Courses (minimum 20 credits)

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.

Research Ethics

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.

Comprehensive Exam 

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)

Doctoral Committee 

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.

Prospectus 

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.

Dissertation 

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.

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.  These credits will be reviewed and those that do not fulfill the PhD competencies may not be accepted. 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.

The advisor works with the students in identifying the course of study in the doctoral program. If the doctoral student does not have a prior public health degree, they must obtain a grounding in public health. See Doctoral Student Handbook.
