PhD in Environmental and Occupational Hygiene


The Environmental and Occupational Hygiene PhD program educates professionals to recognize, assess, evaluate, and control environmental and occupational exposures to chemical, physical and microbiological hazards. Students learn to identify, evaluate, and manage health risks found in a wide variety of community and occupational settings, obtaining advanced research training in exposure assessment and control methods.

Likely Careers

Graduates are employed as industrial hygienists and safety professionals by private industry, government agencies, and environmental consulting firms. PhD graduates also may pursue academic careers.


Requirements: Baccalaureate degree, generally in science or engineering, with coursework in Physics, Chemistry, Biology, and Mathematics. GPA of 3.5 or above recommended. GPA minimum of 3.0 for last 90 credits of study. No specific subject area tests are required. Competitive applicants usually have Graduate Record Examination (GRE) scores above the 65th percentile.
Although students may enter the program with a BS degree, a Master of Science degree is strongly recommended.

Application Deadline:  Dec. 1 for first priority review
