The occupational and environmental health sciences (OEHS) major will prepare you to work in environmental health, occupational health, safety and industrial hygiene. As of 2022, the OEHS bachelor’s program is ranked No. 1 among the top 25 undergraduate programs in occupational health and safety by Best Health Degrees. The goal of occupational and environmental health sciences is to control hazardous workplace and environmental exposures to prevent fatalities, injuries and illnesses that affect the health, performance and well-being of workers and the general public. Purdue’s OEHS program emphasizes hazardous exposure assessment, understanding the relationships between exposure and disease and using engineering controls to eliminate such hazards. Both the Purdue University bachelor’s and master’s programs are accredited by the Applied Science Accreditation Commission of ABET.

“My advice is to be flexible in both your educational and social experiences. I came in as an engineering major, and now I’m interested in pursuing medicine, which is something I never would’ve thought of during my freshman year.”

Why Purdue: I chose Purdue because it offers a challenging education and because it’s close to home!
Favorite Place at Purdue: My favorite place is the climbing wall at the CoRec. It’s a nice place to relax and workout after class.
Advice to an Incoming Freshman: My advice is to be flexible in both your educational and social experiences. You might come to Purdue knowing exactly what you want to do in the future and end up completely changing your mind. I came in as an engineering major, and now I’m interested in pursuing medicine, which is something I never would’ve thought of during my freshman year. Or you might pick up a new hobby – for me, it was climbing!
I’m currently involved in research, and I serve as the vice president internal of Purdue’s Asian Student Union Board.
