PhD in Environmental and Occupational Hygiene

This PhD in Environmental and Occupational Hygiene degree trains scientists and professionals to recognize, evaluate, and prevent exposures that may increase the risk of disease or injury. Our doctoral students work with faculty members to research a variety of health problems and identify, quantify, reduce, or eliminate hazards on the job and in communities. The curriculum includes courses in the supporting sciences of biostatistics and epidemiology, as well as foundational courses in exposure science and risk assessment. Additional courses provide in-depth training the environmental chemistry of pollution and exposure monitoring methods. Research topics include biological, chemical, and physical hazard assessment and controls; respiratory, reproductive, and chronic diseases; epidemiology of occupational and environmental cancers; bio-monitoring and medical surveillance; and occupational or environmental health policy. Students gain a comprehensive knowledge of health and safety principles, strong technical skills, and practical experience.
