Admission Requirements

Students should fulfill Drexel University's general requirements for admission to graduate studies. The subjects normally included in an undergraduate program in chemical engineering provide a satisfactory background. Decisions regarding prerequisite qualifications for students who may be deficient in some areas are made after consultation with the departmental graduate advisor.

The core courses are designed for students with undergraduate training in chemical engineering. However, students with a background in biological sciences and engineering can also enroll in the core courses after completing the necessary basic engineering courses and disciplinary chemical engineering courses. Programs for such students are determined on an individual basis after consultation with the departmental graduate advisor.

Graduate study in chemical engineering is offered on a regular full-time basis and on a part-time basis. Details not covered in the following information may be obtained by contacting the departmental graduate advisor. The General (Aptitude) Test of the Graduate Record Examination (GRE) is required for applicants pursuing full-time study.

Master of Science in Chemical Engineering

Degree Requirements

In general, each program leading to the Master of Science in Chemical Engineering must meet the following requirements: total, 45.0 credits; core chemical engineering, 15.0 credits; area of concentration, at least 15.0 credits; free electives, at most 6.0 credits; research, at most 21.0 credits. Core courses in the chemical engineering Master's program are listed below. A Master's Thesis is optional.

Thesis option: The thesis may be based on either a theoretical or an experimental investigation, or both, of limited scope but involving a significant degree of originality. The nature of the research may involve multidisciplinary areas such as biological engineering, materials processing and engineering, energy and the environment, and other topics. The scope and content of the thesis is guided by the thesis advisor. All students pursuing a Master's with Thesis must complete 9.0 credits of thesis research (CHE 898) and, at the discretion of the research advisor, up to 12.0 credits of independent study (CHE I799).

Coursework-only (non-Thesis) option: Students not pursuing Master's with Thesis may take up to 21.0 credits of independent study (CHE I799) although independent study is not required for a non-thesis Master's. Non-thesis students may also take additional concentration electives beyond the required 15.0-credit series. Non-thesis students may not register for thesis research.

Concentration: All Master's students must complete a 15-credit series of concentration electives. Concentration electives may be chosen from course offerings in chemical engineering, mathematics, science, and other engineering disciplines, and are subject to approval by the departmental graduate advisor. Sample concentration series courses are listed below; there are many other possibilities. Free (non-concentration) electives need only be graduate-level.

Co-op: Students have the option to pursue a co-op as part of their Master's program. In conjunction with the Steinbright Career Development Center, students will be provided an overview of professionalism, resume writing, and the job search process. Co-op will be for a six-month position running in the summer/fall terms. Students will not earn academic credit for the co-op but will earn 9.0 non-academic co-op units per term.

Full-time students usually take the core courses in the first year. Other courses may be substituted for the core courses, if equivalent courses are available and if the substitution is approved by the graduate advisor. Full-time students normally require a minimum of one calendar year to complete their study and research.
