Occupational and environmental health professionals protect individuals from possible health effects caused by environmental hazards, such as lead or air pollution. Purdue’s occupational and environmental health sciences (OEHS) graduate program, which specializes in industrial hygiene, offers both Master of Science and PhD degree programs.

Our mission is to advance professionals, leaders and researchers in industrial hygiene and related fields. The program will prepare you with the knowledge and skills to be an outstanding scientist equipped to protect workers, families and communities from hazardous environmental agents and workplace stressors.

The MS program is accredited by the Applied Science Accreditation Commission of the Accreditation Board for Engineering and Technology. For a complete description of our educational objectives, student outcomes and enrollment and graduation data, visit our accreditation page. As of 2022, the MS program is ranked No. 2 among the top 25 master’s programs in occupational health and safety by Best Health Degrees.

The MS in OEHS is recognized as a Qualified Academic Program (QAP) by the Board of Certified Safety Professionals (BCSP), meeting the qualified credential requirement for the Certified Safety Professional (CSP) certification.
