The Department of Chemical and Biological Engineering offers degrees at the bachelor's, master's and doctoral levels. The department offers two distinct BS degree programs, one in chemical engineering and one in biological engineering.

Chemical engineering prepares students for careers in a range of industries including energy, consumer products, sustainability and semiconductors. Modern industry depends on chemical engineers to tailor manufacturing technology to the requirements of its products, and chemical engineers play a central role in development of new polymeric materials, alternative energy sources and safe, efficient processes for chemical synthesis.

The biological engineering undergraduate program prepares students for careers in biotechnology, pharmaceuticals, medicine and materials. Exploring the structure of protein molecules, the functioning of cells and the growth and regeneration of tissues are among the new frontiers that chemical and biological engineering students will address.

In addition to the standard chemical and biological curriculum, a premedicine curriculum is also offered. The chemical and biological engineering department has active research and educational programs in the exciting field of biotechnology, which involves the use of individual cells and their components for producing pharmaceuticals and other important products. The department is also active in biomedical engineering, which involves medical devices, tissues and biomaterials.

There are opportunities to specialize via electives, independent study, research and senior thesis.

Students can carry out part of their studies in another country while staying on track to a four-year degree. This is a wonderful opportunity to delve into a new culture and learning environment, and can be valuable professional experience given the international ties of many companies and researchers. Many faculty members have significant international experience.

Course codes for these programs are CHEN and BIEN.

Senior Thesis

The department offers this program for undergraduates with a strong interest in research. The student carries out a yearlong project under the direction of a faculty member in lieu of taking CHEN 4130 (for CHEN students) or CHEN 4810 (for BIEN students). Students must apply at the end of their junior year.

Research Facilities

Chemical and biological engineering research facilities are extensive and modern. Nearly all research equipment is interfaced to computers for automated data collection, monitoring and control. A full description of chemical and biological engineering research facilities can be found on the department website.

Faculty

While many faculty teach both undergraduate and graduate students, some instruct students at the undergraduate level only. For more information, contact the faculty member's home department.
