About Us

The University of Michigan Center for Occupational Health and Safety Engineering (COHSE) is a NIOSH Education and Research Center (ERC). Since inception in 1982, COHSE has supported comprehensive graduate-level educational programs to aspiring practitioners and researchers in Industrial Hygiene (IH), Occupational Health Nursing (OHN), Occupational Safety Engineering and Ergonomics (OSE), and Occupational Epidemiology (OE) to help meet the nation’s needs for qualified practitioners and researchers. Our academic programs are complemented with our highly effective Pilot Project Research Training (PPRT) program, Continuing Education (CE) courses, and Visiting Partners Program (VPP). Our success as a center of excellence is predicated on:

  1. An outstanding and dedicated faculty
  2. Interdisciplinary curricula that prepare our graduates for modern practice
  3. Vibrant extramurally funded research programs in many National Occupational Research Agenda (NORA)-related areas that train next-generation research leaders
  4. Multifaceted outreach and CE programs that meet the needs of professionals in our region and beyond
  5. Strong institutional support
  6. Active and engaged alumni, many of whom are leaders in their fields

The US workforce carries a disproportionate burden of preventable job-related morbidity and mortality. By training high-quality practitioners and researchers, COHSE helps to meet critical shortfalls in health and safety services in most small and many larger workplaces, and thereby reduces the incidence and severity of occupational injury and illness.
