The department endeavors to provide for the needs of the chemical industry and for research in Chemical Engineering. The aim is to train engineers who will be mainly concerned with the development and application of manufacturing processes in which chemical, biochemical, and/or physical changes of materials are involved and who will be able to design, construct, operate and maintain the equipment in which these operations and processes will take place.

The undergraduate program offers departmental elective courses in the following areas: Biotechnology and Biomolecular Engineering, Energy and Environmental Technologies, Materials and Nanotechnology and Process Engineering. Each student must select and complete at least three departmental elective courses from these areas. In addition, all students choose three complementary courses with a view towards complementing their engineering education according to their individual interests and one free elective course. These courses may also be selected from any of the aforementioned areas if desired. The selection of departmental elective and complementary courses must be made under the supervision of the departmental advisors.

The course requirement for the Bachelor of Science Degree in Chemical Engineering is a minimum of 142 credit-hours of formal course work. In addition to the course-credit requirements, the equivalent of minimum 60 work-days of industrial training in areas approved by the department, in the two summers following the second and third years, is required.
