The Institute of Occupational and Environmental Medicine is a World Health Organization Collaboration Centre in Occupational Health and has links with scientists in many countries. Research is divided into two overlapping and complementary areas: environment-oriented areas, which follow the tradition of preventive medicine with a focus on causal determinants; and outcome-oriented areas, which are based on clinical medicine and epidemiology.

Following graduation, Postgraduate Researchers in the College MDS gain employment in a variety of areas though with a majority continuing in research, mostly in Academia but also in the Health, Pharmaceutical, and Biotechnology sectors. Others pursue careers in Education, Publishing, Intellectual Property Protection, Technology Innovation, Business, and more besides.
