Please consult the table below for key information about this degree program’s admissions requirements. The program may have more detailed admissions requirements, which can be found below the table or on the program’s website.

Graduate admissions is a two-step process between academic programs and the Graduate School. Applicants must meet the minimum requirements of the Graduate School as well as the program(s). Once you have researched the graduate program(s) you are interested in, apply online.

Fall Deadline December 15
Spring Deadline October 15
Summer Deadline The program does not admit in the summer.
GRE (Graduate Record Examinations) Required.*
English Proficiency Test Every applicant whose native language is not English or whose undergraduate instruction was not in English must provide an English proficiency test score and meet the Graduate School minimum requirements (https://grad.wisc.edu/apply/requirements/#english-proficiency).
Other Test(s) (e.g., GMAT, MCAT) n/a
Letters of Recommendation Required 3
*

The GRE requirement is waived for the fall 2022 and spring 2023 application cycles due to COVID-19.

Students with a strong background in chemical engineering or related field and a strong interest in research are encouraged to apply for admission. Most applicants accepted into the program have grade-point averages well above the Graduate School minimum of 3.0 on a 4.0 scale. All applicants are required to take the Graduate Record Exam (GRE) general test. Applications are evaluated on the basis of previous academic record, GRE scores, letters of recommendation, and personal statement. The Department of Chemical and Biological Engineering does not consider applications for a terminal M.S. degree; the department admits only to the Ph.D. An M.S. degree can be awarded post admission as an alternative to the Ph.D. degree. The M.S. degree is not a prerequisite for the Ph.D. degree.

Applicants with degrees in the physical or life sciences or other engineering fields are encouraged to apply for admission into the Ph.D. graduate program. These students should contact the chair of the graduate admissions committee to discuss their preparation for the graduate program. Students are not accepted for spring semester except when space is available. Fall applications and supporting materials must be received by December 15.

Minimum graduate school requirements

Review the Graduate School minimum academic progress and degree requirements, in addition to the program requirements listed below.

Minimum Credit Requirement 51 credits
Minimum Residence Credit Requirement 32 credits
Minimum Graduate Coursework Requirement 26 credits must be graduate-level coursework. Details can be found in the Graduate School’s Minimum Graduate Coursework (50%) policy (https://policy.wisc.edu/library/UW-1244).
Overall Graduate GPA Requirement 3.00 GPA required.
This program follows the Graduate School’s GPA Requirement policy
(https://policy.wisc.edu/library/UW-1203).
Other Grade Requirements At least two of the core graduate classes must be taken in the first semester of residence in the graduate program, and at least four core graduate classes must be completed with grades of B or better, preferably by the end of the second semester of residence. A student who receives one grade of BC or lower in a core class but who wishes to remains in the PhD program must take the fifth core course or re-take the low graded core course preferably in the third semester, and the student must receive a B or better.

A student who receives more than one grade of BC or lower in core graduate classes will be placed in the M.S. program. Upon successful completion of the M.S. program, the student may petition the full faculty for readmission to the Ph.D. program.

A student who receives an average of 3.0 or higher on their preliminary exam becomes a candidate for the Ph.D. program. A student who does not receive an average score of 3.0 or higher in the qualifying process is placed in the M.S. program. Upon successful completion of the M.S. program, the student may petition the full faculty to be readmitted to the Ph.D. program.
Assessments and Examinations A Ph.D. candidate who has met the grade requirements must complete a preliminary exam consisting of a written report and oral examination.

During the fall semester of the fourth year of the program, candidates will participate in a mandatory research progress meeting with their thesis committee.

The Ph.D. candidate defends a written thesis in a final oral examination.
Language Requirements No language requirements.
Breadth Requirement All doctoral students are required to complete a doctoral minor or Graduate/Professional certificate.

The Ph.D. candidate is required to undertake a program of coursework in a field other than chemical and biological engineering. This requirement may be satisfied by an external minor (option A), a distributed minor (option B), or a Graduate/Professional certificate (option C).

The minor/certificate, whether Option A, B, or C, is designed to represent a coherent body of work, and should not be simply an after-the-fact ratification of a number of courses taken outside the major department. To ensure coherence, the student must consult with his or her advisor. The Ph.D. Minor Agreement Form should be submitted for approval at an early date, before the student is halfway through the proposed course sequence.

Students must complete at least six semester courses (totaling at least 18 credits) in the CBE department. Four courses will be core CBE courses and two will be CBE electives, chosen at the discretion of the student in consultation with their advisor. These classroom courses shall be in the range numbered 500-899 and will not be laboratory courses, Independent Studies or Research. Grades of B or better are required in all CBE courses used towards degree requirements.

At least four of the six CBE courses shall be selected from these core graduate courses:

CBE 620 Intermediate Transport Phenomena3
CBE 660 Intermediate Problems in Chemical Engineering3
CBE 710 Advanced Chemical Engineering Thermodynamics3
CBE 735 Kinetics and Catalysis3
CBE 781 Biological Engineering: Molecules, Cells & Systems3

At least two of the core graduate courses must be taken in the first semester of residence in the graduate program, and at least four core graduate courses must be completed with grades of B or better, preferably by the end of the second semester of residence. A student who receives one grade of BC or lower in a core class but who wishes to remains in the PhD program must take the fifth core course or re-take the low graded core course preferably in the third semester, and the student must receive a B or better. Students are expected to take a total of four courses in their first semester of residence.

The requirement of four core CBE graduate courses shall not be met by substitution of other courses. Students matriculating with an M.S. degree from another university may, with department approval, use up to two courses from their M.S. work toward the requirement of six CBE graduate courses.

Students taking advanced courses outside the department in excess of breadth requirements may, with department approval, use up to two of these courses toward the requirement of six CBE graduate courses. Seminar courses may not be used to satisfy CBE course requirements.

Elective course requirement: Students must complete at least one course totaling at least three credits. Courses must be numbered 300 and above. A B average is required. Pass/fail or audit courses may not be used for the elective course requirement. Courses used to satisfy the breadth program may not be used for the elective course requirement. Advisor approval is required and secured through submission of the Ph.D. Elective Course Approval Form. Elective courses can be foreign language courses.

Teaching assistantship: Each student in the Ph.D. program is required to serve as a teaching assistant (TA) for two semesters. Under normal circumstances, each student should serve as a TA one semester of the second year and one semester of the third year. Requests for alternate arrangements, partial or full waiver of the requirement, should be submitted in writing to the Graduate Program Committee.
