PhD in Global Environmental Health Sciences

The PhD degree in the Environmental Health Sciences 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.

Degree Program Requirements (entry prior to Fall 2018)

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.
