Free electives begin to appear in the Chemical Engineering curriculum in the junior year. These electives give students the opportunity to explore different areas of interest. Some students choose to devote their free electives to the pursuit of an additional major or a minor. If you are interested in exploring different areas of interest for Chemical Engineering careers, we have identified some thematic areas that are highly relevant to Chemical Engineers and gathered lists of suitable courses for each area. These courses might not be offered every semester, and new ones may appear, but these lists will hopefully help you find suitable elective courses. You may choose to explore some thematic area in depth, or you may choose to sample a few areas. Students should check the prerequisites for any courses they consider as electives.

Please note that a 600-level course is considered an advanced undergraduate/beginning graduate course, so all Chemical Engineering juniors or seniors would be well qualified to take 06-6xx courses. 700-level courses are considered to Ph.D. level and are designed to be taken by first year Ph.D. students. Seniors who get mostly A’s in their Chemical Engineering core courses are well-qualified to take 06-7xx courses. When considering 600 or 700 level courses in other majors, you should consider whether your background is a good match, based on the course description.

Please click on one of the topics below to find lists of courses:

Advanced chemical engineering fundamentals

Seniors who have mostly A’s in their chemical engineering core courses are well qualified to take Ph.D. level Chemical Engineering courses. If you are interested in gaining a deeper knowledge of the fundamentals of Chemical Engineering, you should consider the following courses as electives:

Course Description
06-702 Advanced Reaction Kinetics
06-704 Advanced Heat and Mass Transfer
06-705 Advanced Chemical Engineering Thermodynamics
06-713 Mathematical Techniques in Chemical Engineering
06-720 Advanced Process Systems Engineering*
06-722 Bioprocess Design

*Advanced Process Systems Engineering is typically offered in spring semester—appropriate for students who have completed 06-421 Chemical Process Systems Design in Fall semester.

Seniors who typically get A’s or B’s in their Chemical Engineering core courses are well qualified for the Chemical Engineering MS core courses, which emphasize the use of computational tools to solve Chemical Engineering problems. If this interests you, you should consider the following courses as electives:

Course Description
06-623 Mathematical Modeling of Chemical Engineering Processes
06-625 Chemical and Reactive Systems
06-663 Analysis and Modeling of Transport Phenomena

Note: The course 06-606 Computational Methods for Large Scale Process Design and Analysis is not recommended if it is taught in the fall semester (as it normally is), since students in this class are expected to have already completed an undergraduate Processes Systems Design course such as 06-421.

Note: These courses may not be substituted for any of the required core courses for the BS in Chemical Engineering.

Sustainability and environmental aspects

Chemical engineers develop catalysts and processes to improve yields in the production of fuels, and they develop new battery systems, fuel cells and biofuels to help build the renewable energy economy.

Chemical engineers apply their knowledge of transport and reaction processes to model the fate and transport of pollutants in aquatic, soil and atmospheric systems.

Please note that there is a College of Engineering designated minor in environmental & sustainability studies. Courses listed for that minor would certainly be appropriate.
