Core ChBE Course Descriptions for Students Entering Fall 2012 and Later

Courses offered by the Department of Chemical and Biomolecular Engineering for students entering the program Fall 2012 and later may be found under the acronym "CHBE" in the course catalog and on Testudo (, our online service where you will also find admission, registration, financial, class scheduling, residency, and other important information.

If you entered the program in Fall 2012 or later, do not register for courses that use the "ENCH" prefix. Select courses that use the "CHBE" prefix, as shown below.

Please use the following policies to guide you as you select your courses each semester:

  • Follow the sample program as closely as possible. Almost all ChBE courses are offered only once a year. Since the courses build on each other, should you stray from the suggested curriculum, you run the risk of not being able to complete the degree in 4 years.
  • Most courses have prerequisites which must be fulfilled before taking the course, unless you have specific permission from the professor.
