Occupational and Environmental Hygiene Master’s Degree Program*
The part-time/online program can be completed entirely online except for two hands-on courses that take place during the Summer Institute. The program can be completed in two-and-a-half to five years.
In addition to coursework, students will be required to perform an independent professional project that is typically conducted at their place of employment. This project will serve as the basis for both a culminating written essay and an oral presentation to program faculty and students. Some example essay titles are listed below.
- Noise Assessment Within a Food Manufacturing Plant
- Fugitive Combustible Dust Abatement in the Aerospace Industrial Manufacturing Sector
- Evaluating Exposures at a New and Expanding Waste Sterilization and Recycling Facility
- Effectiveness of Hearing Protection Device Fit Testing to Improve In-Ear Attenuation for Large Aircraft Test & Evaluation Workers
- Measuring and Describing the Relationship between Respirable Mass, Airborne Mass, Bulk Powder Dispersibility and Dustiness for Nuclear Material Storage Container Evaluation
- Modeling in Support of Industrial Hygiene Assessment: Aerospace Large Part Solvent Cleaning
- Evaluation of Chemical Fume Hood Inspection Protocols for Chemical Hygiene Officers

Hands-on Coursework in Baltimore
Students attend two separate hands-on courses on our East Baltimore campus during the Summer Institute session held in June. The courses are offered in alternating years and are two weeks in length.
Industrial Hygiene Laboratory—students will learn about methods for quantitative exposure assessment including pump calibration, passive and active sampling, gases and vapor, particulate matter, size-selective sampling; special methods for PM sampling (i.e. fibers, bioaerosols); and direct reading instruments.
Onsite Evaluation of Workplace and Occupational Health Programs—students will visit various industrial sites in the Baltimore region and evaluate the industrial environment including industrial processes, hazards, labor issues, and corporate structure in the context of worker health and safety.
