Occupational Hygiene/Exposure Science

Here you can:

Translate your
research into
policy impact.

Harness your passion for improving public health.
At DEOHS, you can:

construction worker
Help shape health and safety protections for temporary workers and others doing precarious work (the PhD research of Trevor Peckham, pictured above).

Marijuana plants
Identify on-the-job respiratory hazards for workers in the fast-growing cannabis industry.

farmworkers in the sun
Work with our Northwest Center for Occupational Health and Safety to study the health effects of heat exposure for agricultural workers.

Why study Occupational Hygiene/Exposure Science?

Exposure scientists quantify hazardous environmental exposures and their risk to human health. Occupational hygienists apply those skills in workplace settings by recognizing, evaluating and controlling exposures from risks such as heat, noise, dust and psychological stress that can cause occupational diseases and aggravate other health problems.

MS and MS Applied students can choose between our areas of emphasis in occupational hygiene and exposure science. For PhD students, these areas of emphasis are combined.

Our Northwest Center for Occupational Health and Safety, part of DEOHS, offers traineeships for the Industrial Hygiene/Exposure Science training program, funded by the National Institute for Occupational Safety and Health.

As a student in Occupational Hygiene/Exposure Science, you will:

  • Choose an area of emphasis in occupational hygiene or exposure science (for MS and MS Applied students) or a program including both areas of emphasis (PhD students).
  • Take common core courses introducing foundational concepts and skills, including: risk assessment, management and communication; assessment and management of exposures to environmental hazards; core principles of toxicology; and how to use a One Health approach to address complex challenges.
  • Learn how to monitor, analyze and control exposures to chemical, physical and biological agents in hazardous chemicals in a variety of settings. Students choosing the Occupational Hygiene area of emphasis receive additional training in occupational and environmental disease and industrial hygiene.
  • Complete a culminating experience (thesis, project or dissertation) showcasing your ability to integrate the skills you have learned to address an environmental or occupational health problem.

Since joining the department, I’ve been impressed with how much research is going on and how many opportunities there are for students to get involved.
