What is Environmental and Occupational Health?

Environmental and occupational health looks at how environmental and occupational exposures impact human health. It explores the underlying science and policy for issues such as sustainable cities and food systems, climate change mitigation, workplace safety and risk management. Students learn from and work with our faculty on conducting cutting-edge research that is helping to dictate environmental and occupational health policy. Our faculty have been called upon by Congress to offer their expertise in areas like antibiotic resistance, climate change, occupational safety and environmental exposures, influencing critical regulations and legislation like the Toxic Substances Control Act.
