  4. A minimum of twenty-four (24) credits of coursework, determined by the area of specialization, including 12 credits (minimum) of required core courses; and 12 credits (minimum) of advanced-level (5xx level or above) elective engineering courses.
2. Research Credits: A minimum of thirty (30) credits of doctoral research, including a maximum of 10 credits of xxx895 (doctoral research), and a minimum of 20 credits of xxx899 (dissertation). Registration in xxx899 is contingent upon successful completion of the candidacy exam.
3. Flexible Credits: A minimum of 20 credits, from a combination of dissertation and/or coursework at the 500-level or above.

For students entering the doctoral program with a master’s degree, the student’s combined master’s and doctoral coursework must satisfy all content requirements described above. At least 20 credits of coursework required for the doctoral program must be taken at CSU. At least 30 credits of research (xxx895 and xxx899) must be taken at CSU. And at least 60 credits (total) must be taken at CSU. The graduate program committee of the specialization is responsible for assignment of credits from the student’s MS program to the PhD in Engineering program.

2. Satisfactory completion of the Qualifying Examination.

3. GAC approval of the Dissertation Committee and Plan of Study and satisfactory completion of the doctoral Candidacy Examination.

4. Completion of a doctoral dissertation and successful oral defense of the dissertation.

5. Compliance with all requirements of the College of Graduate Studies for regular graduate student status and graduation.

Advising

When a student is admitted, an interim advisor is assigned in his/her specialization to assist the student in completing a preliminary study plan. The interim advisor is usually the person in charge of the specialization area. Before sixteen credits of course work have been completed, the student must propose a dissertation advisor and begin plans for the dissertation.

The students are encouraged to form their dissertation committee as soon as possible, in consultation with their advisor, who normally chairs the committee. The functions of the student’s dissertation committee are: administer the candidacy exam and determine pass/fail; monitor the progress of the student’s research; administer the oral defense and determine pass/fail; and approve the dissertation.

The dissertation committee must include a minimum of five graduate faculty members, including the chair, and including at least one from outside of the Engineering College. Usually, an additional member is added when an off-campus, industrial advisor is involved in the dissertation work. This off-campus project advisor may be a member of the dissertation committee but does not have voting rights, unless he or she holds graduate faculty status. The Graduate Affairs Committee (GAC) of the College reviews the composition of the advisory committee and approves or recommends changes to attain a membership balance that is knowledgeable in all facets of the dissertation topic. Finally, an additional member may be selected by the Dean of the College of Graduate Studies. Any subsequent changes to the dissertation committee membership must also be approved by the GAC.

Examination

Individuals admitted to the program become candidates for the Doctor of Philosophy in Engineering degree after:

Completing all prescribed course work;
Passing the qualifying examination; and
Passing the candidacy examination.

Qualifying Exam: The purpose of the doctoral qualifying examination is to evaluate a prospective student’s mastery of the subject matters that are fundamental to the chosen engineering discipline/concentration beyond what is demonstrated by the grades obtained prior to entering the doctoral program. The student must demonstrate broad understanding of engineering science and mathematics and special knowledge and readiness to pursue further study in a specific discipline/concentration. The examination must be taken before completion of 24 credits in the graduate program.

The student’s performance on the qualifying examination determines the future course of study. Students who pass continue the program of study. Those who pass conditionally are subject to additional course work and/or re-examination. Only one re-examination is permitted. Students who fail twice are dismissed from the doctoral program. The qualifying examination is administered by the Graduate Committee of the student’s respective department. The minimum College standards require the examination to be written, with a minimum of three topics, with minimum of two hours per topic. The subjects and examiners must be approved by the department faculty. Students should determine from their department office the exact nature of their examination and the dates on which it is offered. All students intending to take the examination are required to notify their respective department office at least four weeks before the scheduled examination date.

Candidacy Exam: The purpose of the doctoral candidacy examination is to assess a doctoral student’s maturity and preparation to continue independent research in a specific research topic. The examination should be taken before completing 15 credit hours of doctoral research (xxx895). Students are not permitted to register for dissertation credits (xxx899) before successful completion of the Candidacy Exam. For the candidacy examination, the student must prepare a written dissertation proposal based on a scholarly review of literature in the dissertation area. Prior GAC approval of the student’s dissertation committee (on the Dissertation Proposal Approval Form) and study plan is necessary to conduct the candidacy exam. The dissertation committee administers the doctoral candidacy examination. The exam must involve a public seminar followed by oral examination by the dissertation committee which is closed to the public. Based on the examination results, the student either passes and has the proposal accepted with a general understanding that the successful completion of the work presented results in the award of the Doctor of Philosophy in Engineering degree, or fails and has the proposal rejected. The candidacy exam may be taken a maximum of two times, with the second attempt within six months of the first attempt.

Dissertation

The dissertation, a concentrated, in-depth, independent study of an appropriate engineering problem, is the most distinguishing feature of doctoral study. At least thirty credits of dissertation work are required, which correspond to at least one year of full-time study. Students cannot take Dissertation (xxx899) credits before successful completion of the Candidacy Exam. The dissertation advisor and advisory committee, after approving a dissertation topic, monitor the student’s progress and approve the final written dissertation after a successful oral defense.

Once a student begins the dissertation study, he or she must register for a minimum of three credit hours per semester until the minimum of thirty credits is completed. After that, the student shall maintain a minimum registration of one credit hour per semester until the dissertation is completed.

The dissertation is not limited to the physical aspects of the engineering problem, but should include, where pertinent, economic considerations, environmental impact, social implications, and other interdisciplinary factors relevant to the specific topic.

In many cases, the dissertation study is conducted off-campus in an industrial or governmental setting. This type of off-campus study is defined as an internship; it gives the student an intimate and practical exposure to real problems of engineering. The student’s industrial internship dissertation project must be cleared for publication by the industrial or governmental organization in which the work is done. This written clearance must be included in the dissertation proposal.

The student intern may have an off-campus advisor who may become a member of the student’s advisory committee. This off-campus advisor is expected to work closely with the student and with a faculty as academic advisor. However, the faculty academic advisor remains the chair of the advisory committee, ensuring that ultimate control of the dissertation resides with the University.

Dissertation Defense and Degree Completion

One paper from the student’s dissertation research must be submitted for publication in a peer-reviewed journal, prior to the dissertation defense. The dissertation defense is a public presentation of the dissertation, followed by an oral examination by the dissertation committee which is closed to the public. The dissertation committee determines pass or failure.

The doctoral program director ensures that all program requirements are satisfied before signing the degree completion (including: course and research credits, successful completion of qualifying, candidacy and dissertation defense exams, publication requirements, and all program assessments). The Notice of Completion is signed by the dissertation committee chair, the department chair of the program of specialization, and the doctoral program director.
