Program Description

An individual plan of graduate study in chemical engineering compatible with the student’s interest and background is offered. The primary emphasis of the program’s research activities is biotechnology and biomedical engineering. Cross-discipline thesis research projects in these areas are encouraged.

Program Specialties

The admission requirements and procedures correspond to the requirements set forth by the UMBC Graduate School. Opportunities are available for undergraduate students to enroll in the B.S./M.S. program in their senior year. For students with non-chemical engineering B.S. degrees wishing to enter the M.S. or Ph.D. program, a series of courses at the undergraduate level are required prior to beginning graduate courses in Chemical Engineering. In general, those classes can be taken during the student’s first year in graduate school.

Degree Requirements

For the M.S. in Chemical Engineering, a minimum of 30 credit hours of coursework in technical areas relating directly to chemical engineering are required. Up to nine credit hours of advanced upper-level undergraduate courses may count toward this minimum. M.S. thesis degree candidates are required to pass an oral qualifying examination, perform a minimum of six credit hours of thesis research and pass a final thesis defense.

Ph.D. in Chemical Engineering

The Ph.D. is awarded only upon sufficient evidence of high attainment in scholarship and the demonstrated ability to engage in independent research in the field of chemical engineering. It is not awarded for the completion of course and seminar requirements, no matter how successfully completed. A minimum of 27 credit hours of courses numbered 600 or higher, approved by the program, are required. Appropriate courses taken while earning the M.S. degree from the program may be used to partially fulfill this requirement.

A maximum of six credit hours of ENCH 648, Special Problems may be used in fulfilling this requirement. In addition to the 27 hours of course work, a minimum of 12 credit hours of ENCH 898 or ENCH 899, Doctoral Dissertation Research are required. Courses taken to fulfill the requirements of the program must be approved in advance by the chemical engineering graduate program director and by the student’s advisor, if one has been selected. All Ph.D. candidates are required to take five required graduate course covering topics in advanced mathematics, biochemistry, kinetics, thermodynamics and transport phenomena. Students are required to pass written and oral qualifying examinations. The examinations are given annually, and the student has two opportunities to pass each exam. Additional requirements are imposed by the Graduate School.

Post-Baccalaureate Certificate in Biochemical regulatory engineering

This graduate certificate includes completion of 12 credits by taking the sequence of four courses ENCH 660, ENCH 662, ENCH 664 and ENCH 666. The certifcate provides a comprehensive exposure to the issues related to obtaining and maintaining regulatory agency approval (such as, from the Food and Drug Administration) for biopharmaceutical products.

Facilities and Special Resources

The program’s research facilities include state-of-the-art laboratories at the Technology Research Center and the $26 million Engineering Building. These facilities are extensively equipped with modern fermentation, cell culture, chromatography, microscopy, proteomics and other bioanalytical equipment. Microcomputers provide the capabilities for data acquisition, analysis, modeling, simulation and control within these facilities.

Financial Assistance

Graduate teaching and research assistantships are available to highly qualified candidates through the program.
