Skillful and creative applications of the principles of chemistry, biochemistry, biology, mathematics, and physics are needed to solve the problems now confronting society. Whether these problems involve energy, food, health, materials or environmental quality, the modern chemical engineer is the professional concerned with finding economically and socially acceptable solutions. The program prepares graduates for employment in a great variety of industries including the chemical, petroleum, biochemicals, pharmaceutical, paper, environmental, fibers, plastics, food, electronics, and consumer product industries. Students may customize their academic program around an industry of their interest by judiciously selecting electives. For example, areas of focus such as polymers, biotechnology, marketing, and environmental chemical engineering are common choices.
The objective of the undergraduate program is to produce chemical engineering graduates who, within five years of completing the BS degree, will be successful in a variety of professional careers, including those outside of traditional chemical engineering fields as evidenced by one or more of the following achievements:
Sustaining a career as a problem solver in engineering or other fields that require analytical skills
Professional advancement in positions of increasing leadership and/or responsibility within their chosen career field
Attainment of an advanced degree or advanced certification leading to a career in engineering or science, business, law, medicine, or academia
Bettering society through professional or personal service
The curriculum has been developed to meet the department goal and the objectives for the graduates. The curriculum is demanding and a GPA of at least 3.0 is recommended for transfer into the program at the sophomore level. An average GPA of at least 2.00 in all ChE courses attempted is required for continued enrollment in the department. The department has specific grade policies for continuation in the program and for graduation. For further information on these policies, please contact the department.
The chemical engineering curriculum integrates studies in thermodynamics, fluid mechanics, heat transfer, mass transfer, process control, reaction kinetics, plant and process design, verbal and written communications, and reaction kinetics, along with professional ethics and environmental awareness. Students gain hands-on experience with the equipment described in the courses during the summer Unit Operations Laboratory. The laboratory and the senior design courses are recognized as two of the high points in the undergraduate program. Throughout these studies, the student learns the elements of the design of chemical processes and chemical processing equipment. The experience culminates in participation in a national senior-level design contest. The computer is a necessary tool in all the courses and the same software used in industry is used in the design courses.
In addition to the basic undergraduate program outlined here, more sophisticated and specialized programs leading to the M.S. and Ph.D. in chemical engineering also are offered (see Graduate Catalog).
The department participates in the Cooperative Education Program whereby qualified students may alternate periods of study with periods of professional employment.

The following are special focus areas students can use as electives. Lists of approved courses for these focus areas are available in the Department of Chemical Engineering.
Marketing and Chemical Distribution
As part of progress toward a degree, a student must have a grade of C- or better in all ChE-prefix courses and maintain a minimum in-major GPA of 2.0 or above. If the in-major GPA drops below 2.0 at any time, students will be placed on departmental probation. Students cannot remain on departmental probation for more than two consecutive semesters. In the case that a student has not achieved an in-major 2.0 or better after two semesters, the student is prohibited from registering for any ChE courses for at least one semester and, after that, only with permission of ChE department head. All ChE credits are used to calculate in-major GPA.
Students who plan to co-op should talk with with Dr. Goldstein (339 ICTAS Building) of the ChE department.
