Occupational and Environmental Health and Safety


The Department of Occupational and Environmental Health and Safety was instated under the auspices of the Ghana-Michigan Chapter research, Global Environmental and Occupational Health (GEOHealth) program in the year 2009, to focus on Occupational and Environmental Health and Safety Policies. In the year 2015, the U.S. National Institute of Health /Fogarty International Center, in partnership with the International Development Research Center (IDRC) and through the GEOHealth, the Department was initiated to the current Occupational and Environmental Health and Safety (OEHS) MPH/MSC program. 


To become a center of excellence in training and conducting cutting-edge research needed for formulation and updates of occupational and environmental health and safety policies for service delivery to propel Ghana towards the realization of Sustainable Development Goals.

Mission Statement

The Department of OEHS exists primarily to create enabling platforms for enhancement of knowledge and understanding of the associations between human life, human activities, environment, and health; acquisition of skill sets for the identification and quantification of environmental and occupational hazards; and development of effective, efficient, cost-effective, culturally acceptable and sustainable intervention strategies to control the hazards and promote quality of life.



The programme is designed to provide high-quality multidisciplinary training in Occupational and Environmental Health and Safety (OEHS); equip graduates with knowledge, skills, and tools that fit into many sectors of the economy; undertake cutting-edge research, and implement OEHS policies and guidelines to improve the health of people.


Specifically, the programme seeks to:

  • equip graduates with skills and competencies that will enhance identification and control of health risks posed to communities and workers via exposure to certain physical, chemical, and biological factors from their environment/occupational settings.
  • produce well-trained graduates who would be able to demonstrate an understanding of the theory, research, and practice of public health in Occupational and Environmental Health and Safety situations.
  • provide outstanding, comprehensive academic training in occupational and environmental health and safety that will prepare graduates to pursue careers and assume leadership roles in public health practice and/or cutting-edge research.
  • produce and facilitate evidence-based policies to guide the implementation of OEHS programmes in public and private institutions.


Competitive advantage

Located in the science and technology university, our department has at its disposal a cream of experts in other sciences, technologies, and humanities which could be tapped to advance our vision. The department has another geographical advantage since it is located almost at the center of Ghana thus attracting a lot of potential students and the general public.

Partnership and collaboration
