Exposure Science-Industrial Hygiene

Students in hazmat suits

Occupational Health Sciences - Industrial Hygiene (OHS-IH) underpins several of the disciplines comprising the Environmental Health Sciences. When applied to occupational health, OHS-IH falls within the domain of Industrial Hygiene (IH). By tradition, the field of IH applies knowledge and principles drawn from the physical and life sciences, engineering, statistics, psychology, and program management to the protection of workers (and the general public) from chemical, biological, and physical agents of disease. Considering IH in the broader context of OHS-IH the contributions IH professionals are making in modern global society (within and beyond the boundaries of the workplace), and our evolving understanding of health risks as a function of time/life-stage, we have adopted the hybrid term OHS-IH to describe our academic program.

IH professionals are concerned with the myriad aspects of evaluating, mitigating, and managing workplace hazards, including toxic gases and vapors, dusts, (bio-)aerosols, mold, engineered nanomaterials, pathogens, noise, ionizing and non-ionizing radiation, ergonomic stresses and safety hazards.

As we move toward a more holistic view of human health and well-being (i.e., Total Worker Health), the roles of IH professionals are expanding to include health promotion, wellness, and emotional and mental health issues associated with increased workloads and associated job stress.

Increasingly, responsibility for environmental issues outside of the workplace, such as hazardous waste, residential indoor air quality, ambient air and water pollution, and ecological balance are also falling within the domain of the practicing Industrial Hygienist.

Among the activities in which IH professionals may be engaged are the following:

  • Measurement of contaminant levels in the air, on surfaces, and in biological fluids
  • Design of exposure assessment strategies (e.g., for estimating health risks)
  • Statistical analysis of data sets to inform decision-making
  • Management of occupational and environmental health programs
  • Training of workers about hazards and safe practices
  • Promotion of healthy working conditions
  • Demonstration of compliance with regulations and guidelines limiting harmful exposures
  • Research on the relationships between exposure and health effects
  • Development and implementation of new monitoring technologies and methodologies
  • Provision of service to the public and/or professional societies (e.g., AIHA)
  • Maintenance of ethical practices in all aspects of their professional activities
  • Engagement in lifelong learning

IH professionals are employed by numerous private and public sector organizations include large (often multi-national) corporations; insurance companies and environmental consulting firms

 Distinguishing features of the University of Michigan IH Program include the following:
  • One of the longest-standing and most highly regarded IH programs in the country
  • Dedicated core faculty that are highly effective teachers and mentors, with active research portfolios addressing issues at the cutting edge of the field
  • Diverse supporting faculty with a wide range of experience as practicing IH professionals
  • Rigorous curricula coupled with an array of other enriching experiences to provide comprehensive practitioner and research training
  • Continuous record of accreditation by ABET for over 30 years
  • An integral component of the Michigan Education and Research Center (ERC), which has been sponsored by NIOSH for over 42 years
  • An award-winning IH student organization that provides a tight-knit community of friends/peers
  • Over 800+ alumni, many of whom hold influential, leadership positions in private industry, government, and academia in the U.S. and throughout the world

The Industrial Hygiene track provides additional expertise to the Environmental Health Sciences Master of Public Health (MPH), Master of Sciences (MS) and Doctor of Philosophy (PhD) degrees. Some relevant aspects include:
  • The MPH and MS require four semesters to complete
  • The MPH includes a summer internship (field experience), typically in private industry or with a governmental agency, either in the U.S. or abroad
  • The MS degree includes a focused thesis project guided by one or more faculty mentors.
  • The PhD degree entails in-depth training/mentorship in research skills, and the generation of high-impact, scholarly research findings that are published in the peer-reviewed scientific literature
  • The curricula are comprehensive, yet sufficiently flexibility to permit students to pursue any of a number of other interests, including "minor" concentrations and Certificate Degrees
  • Applicants should have a strong interest in science and health, an undergraduate degree in some field of basic or applied science, and, at a minimum, should have taken courses in biology and/or physiology, general and organic chemistry, physics, and calculus.

Applicants to the track in Industrial hygiene must have a strong background in the natural sciences. Minimum requirements for admission include one course on each of the following topics:

  • general biology
  • general chemistry
  • organic chemistry
  • physics
  • calculus 

Some deficiencies may be made up after admission to the program. Courses taken to fulfill basic deficiencies do not count toward fulfillment of the degree's course requirements. Please visit the School of Public Health for more information on the application process for MS, MPH, and PhD. 

All MS and MPH students will be automatically considered for funding upon completing of their application. PhD students will be fully funded during their time in the program. Industrial Hygiene offers additional funding opportunities for highly-qualified students through different funding mechanisms:

  • Traineeships from our NIOSH ERC, Center for Occupational Health and Safety Engineering (COHSE) (U.S. citizens and permanent residents)
  • Grants and scholarships from the School of Public Health (MPH) and the Rackham Graduate School (MS,PHD)
  • Graduate Student Instructor (GSI) posititions in EHS or outside the department 
  • Research assistantships with faculty resarch grants
  • Smaller scholarship awards from external organizations i.e. American Industrial Hygiene Foundations (AIHF), Chevron, and the 3M Corporation 

The (ExS-)IH program has maintained a 6-yr average enrollment of 24 students per year and a graduating cohort size ranging from 7-11 students. Listed below are the enrollment and graduation figures. Our record of career placement is outstanding.
