Johns Hopkins Occupational & Environmental Hygiene Program

Johns Hopkins Occupational & Environmental Hygiene Program ABET-accredited program in occupational and environmental hygiene: full-time/on-campus and online/part-time master's degree options

The overall goal of the Occupational and Environmental Hygiene (OEH) master’s degree program is to provide students with the tools needed to address the broad spectrum of environmental health problems they will encounter throughout their professional careers. Addressing problems associated with occupational health, air pollution, and other environmental health factors requires a complex skill set

that includes training and understanding in chemical, biological, physical and engineering sciences. The part-time/internet based option was developed so that working professionals can have this training available in a flexible format so that they can continue to work while earning a degree.
