The roots of the School of Chemical, Biological and Environmental Engineering (CBEE) at Oregon State University trace back to 1917, with the establishment of the Department of Chemical Engineering.

In 2002, the bioengineering undergraduate program was moved into the department’s administration, followed in 2005 by the environmental engineering undergraduate program. The department was subsequently renamed to better reflect its activities across the three disciplines. The Bachelor of Science and Honors Bachelor of Science degree programs in Chemical Engineering, Bioengineering and Environmental Engineering are accredited by the Engineering Accreditation Commission of ABET, Graduate programs leading to master of engineering, master of science, and doctor of philosophy degrees are also offered in all three disciplines.  

The school emphasizes the integration of chemical, biological, and environmental engineering principles and practice in a student-centered learning environment to provide work-ready graduates and technical solutions for a sustainable future. Research expenditures exceed $8.9 million per year. Current emphasis areas include thin films and nanostructured materials for renewable energy and electronic device applications, bioprocess engineering and biofuels, biomaterials and therapeutics, transport and remediation of contaminants in the subsurface, interaction of nanomaterials with the environment, microtechnology for chemical and energy processing applications, and engineering education research
