Ph.D. in Engineering (Computer Engineering Specialization)

The purpose of the Ph.D. program in Engineering (Computer Engineering Specialization) is to provide qualified candidates with the opportunity to pursue a course of study that will bring them to the frontiers of knowledge in an area of computer science and engineering and engage them in high quality research under the direction of a member of the graduate faculty of the department. This research should culminate in a dissertation presenting significant results which are publishable in recognized refereed journals.

A successful student will complete meet the breadth and depth requirements as descripted in the program of study section, successfully pass the below examinations, and conduct research leading to a dissertation as detailed in this document.

Examinations

A Ph.D. student must pass the following examinations:

  1. Qualifying Exam
  2. Comprehensive Exam
  3. Final Oral Exam (presentation of dissertation)

Choosing an Advisor

The choice of an advisor based on your goals for a Ph.D. degree is critical to success in your work. It is important to realize that the research program is a cooperative effort between the student and the advisor. The advisor has the overall responsibility for the direction and course of the student's research program. The advisor must be a fellow of the graduate faculty. Once you have made the selection of your advisor, you must inform the graduate secretary.

Qualifying Examination

A graduate student working towards a Ph.D. must pass a Ph.D. Qualifying Exam. The purpose of the Qualifying Exam is to test the student's basic preparation in researc and in topic areas that are considered core to computer science and engineering. Refer to the Ph.D. Qualifying Examination Process documentRegistration Form, and Qualifying Exam Grading Rubric for more details. 

A student admitted to the Computer Science and Engineering Ph.D. program with an M.S. received at the university or elsewhere must fulfill his/her Qualifying Examination requirement no later than the third semester after admission. A student admitted to the Computer Science and Engineering Ph.D. program without an M.S. must fulfill his/her Qualifying Examination requirement no later than the fourth semester after admission. A student may take the exam no more than twice.

A student cannot form his/her Ph.D. Supervisory Committee before passing the Qualifying Examination and thus the Program of Studies for the Ph.D. can not be approved before the student has passed the Qualifying Examination. Also, it should be noted that according to Graduate College requirements, a student should not be beyond the half-way mark (that is 45 credit hours applicable towards the degree) when her/his program of studies is approved.

Supervisory Committee

The purpose of the Supervisory Committee is to assist the student in preparing a program to enable success in the Ph.D. program and in evaluating the research.

The supervisory committee can be formed only after the candidate has passed the qualifying examination, according to the schedule stipulated by the Graduate Studies.

Upon recommendation of the departmental or area Graduate Committee in the student’s major, the Dean of Graduate Studies appoints, for each student, a supervisory committee of at least four Graduate Faculty. All professors on the supervisory committee must either be on the Graduate Faculty or be non-Graduate Faculty approved to perform specified Graduate Faculty duties. The student’s dissertation advisor serves as the chair of the supervisory committee. If the candidate has two dissertation advisors, both serve as co-chairs of the supervisory committee. When the candidate’s advisor(s) belong to just one department (CSE/EE), the supervisory committee must include at least one member from another department (EE/CSE), who also serves on the reading committee. The student and the advisor(s) must then submit the "Recommendation for Appointment of a Supervisory Committee for the Doctoral Degree" form to the Graduate Committee chair for his/her signature. After the approval by the Graduate Committee Chair, the form is forwarded to the Dean of Graduate Studies for final approval of the Supervisory Committee.

As one additional option, as of February 12, 2009, a Supervisory Committee may be augmented by the addition of one external expert. Such an expert must hold a doctoral degree appropriate to the discipline and have academic accomplishments comparable to the criteria for graduate faculty. Such "courtesy" members may serve as readers and have full voting rights. Please refer to the Courtesy Members of Doctoral Supervisory Committees document for further details and a link to the form that must be completed.

Program of Study

A total of 90 credit hours are required which must consist of the following: 

  • 51 to 63 hours of regular course work compliant with the Breath Requirements, of which at most 9 credit hours of the following independent study type courses: CSCE 896 (when taken as an independent study), CSCE 897, CSCE 898, or CSCE 996. At most, 6 credit hours of CSCE 899 (master's thesis) can be counted towards regular non-independent study course work. 
  • 3 to 9 hours must be Directed Doctoral Research (CSCE 991)
  • 18 to 36 hours must be Dissertation Credits (CSCE 999)
  • No fewer than 45 credit hours must be completed at the University of Nebraska. 

The program of study must be filed with the Graduate Studies office before the student has completed 45 credit hours. The supervisory committee should meet to review and approve the program of study and general area of research for the dissertation. A Report of the Supervisory Committee on Program of Studies for the Doctoral Degree is then forwarded to the Graduate Studies office. Any subsequent change in the program or in the dissertation topic must be approved by the supervisory committee and the action reported to Graduate Studies. The program of study cannot be filed until the student has cleared all the deficiency courses listed in his or her Certificate of Admission.

For more details, refer to the Ph.D. Requirements document

Breadth Requirements

At least three courses from one track, at least three courses from the remaining tracks, two courses for a minor in CS or EE approved from courses not in the tracks: 1: Circuits and Cyber-Physical Interfaces, 2: Systems, 3: Communications, Networking and Signal processing.

Note: For details see the Track Listing.

Additionally, the student must attend at least 30 departmental colloquia, doctoral oral presentations, and/or master's thesis presentations during the Ph.D. program. A sign-up sheet is used during these events as proof of attendance. 

Note: Master's project presentations may not be used to fulfill this requirement.

Directed Doctoral Research course: CSCE 991

At least 3 hours of research (up to 9 credit hours) with chosen supervisor on a topic directly related to the dissertation. This course provides a directed research experience with a faculty advisor as a gateway to doctoral dissertation research. 

Note: This course is a pre-requisite for CSCE 999.  

Every Ph.D. student should take this course and pass before they take CSCE 999 dissertation credits. For a passing grade the student must (a) submit a written report which will be evaluated and graded by the supervisor, and (b) pass the PhD Qualifying Examination. 

Comprehensive Examination

After a student has reached a point in their studies where they have substantially defined their Ph.D. research topic and completed preliminary work toward that topic, it is important that they demonstrate their readiness to conduct that research, and the sufficiency of their background preparation in that area. The comprehensive examination is the mechanism for achieving this.

The comprehensive examination will be conducted by the Ph.D. Supervisory Committee. The examination will be conducted after the student has completed at least 54 hours of course work and has spent time working on one or more specific research problems that are expected lead to their dissertation. The exam must be completed no later than 7 months prior to the student's Ph.D. defense.

The comprehensive examination shall consist of two parts: a written dissertation proposal followed by an oral presentation. The written proposal shall be sent to the student's Supervisory Committee at least 2 weeks prior to the date of the oral presentation. The oral presentation shall involve a formal presentation of the proposal by the student, of duration between 30 and 45 minutes. The oral presentation will be followed by a question-and-answer period. The questions may pertain to any aspect of the student's proposal, oral presentation, and planned research.

The candidate’s supervisory committee may choose from one of the following two formats for their written dissertation proposal. Either by writing an in-depth dissertation proposal, including a comprehensive review of the literature describing the state-of-the-art related to the broader topic or by preparing a research proposal similar in form and contents to an NSF-proposal.

The Supervisory Committee will report its decision to the student and, in writing, report results to the Graduate Secretary and Graduate Committee (these results will then be reported to the Graduate College).

If a student fails the Comprehensive Examination, the Supervisory committee may decide to give the student a second chance, making particular recommendations for improvements, or they may recommend termination of the student's graduate status. A second exam may not be attempted earlier than the following academic term. 

Failure to pass the Comprehensive Examination in will result in the student's dismissal from the Ph.D. program. The letter of dismissal will be issued by the Graduate Committee and Graduate Chair, following receipt of a recommendation and report from the Supervisory Committee. The student will have the usual right to appeal dismissal decisions to the Graduate College.

No more than two attempts to pass the Comprehensive Exam will be allowed.

Candidacy

Upon the successful completion of the Comprehensive Examination, the Supervisory Committee will normally recommend the student for admission to candidacy. The Committee, however, may require additional examinations.The student must file the Application for Admission to Candidacy form with the Office of Graduate Studies. The term for candidacy is three years and the student is expected to complete the dissertation during this period. Following admission to Candidacy the student must register for graduate classes during each academic year semester until he/she receives the Ph.D. degree.

Dissertation

All Ph.D. students must complete a dissertation under the supervision of a fellow of graduate faculty. It is expected that the work done makes original contribution to the field. It is expected that the work is of a quality that can be published in refereed journals, if it has not already been published. The student is required to write the dissertation in a standard style (Use the "Guidebook for Preparing your Thesis or Dissertation" available from the Office of Graduate Studies.) LaTeX templates are also available on the departmental computers.

Following a thorough review by the advisor, copies of the dissertation are given to the members of the Reading Committee (a subset of the Supervisory Committee). The student must give the committee at least two weeks for review. Upon approval of the Reading Committee a copy of the completed "Application for Final Oral Examination" form and a copy of the dissertation is submitted to the Office of Graduate Studies, at least three weeks prior to the final oral examination.

Final Dissertation: After appropriate changes have been made to the dissertation based on the comments of the committee, and the supervisory committee has approved the dissertation, the student must make several copies of the dissertation. The student is required to give a hard-bound copy to the advisor as well as the departmental office. It is also customary to offer each member of the supervisory committee a copy of the final report. The student must also submit two unbound copies to the Library.

Final Oral Examination (Thesis Defense)

The final oral examination is required for all Ph.D. students. The oral examination will be scheduled for two hours and consist of the presentation and defense of the research. The presentation is open to the public and the student is required to give an abstract (electronic copy) to the office to be used for advertising. After the public presentation and a question-and-answer period, the remainder of the examination is conducted privately by the supervisory committee. The supervisory committee may require the student to make changes to the dissertation and/or conduct additional research and the advisor is generally responsible for making sure that the work is completed. The advisor decides on the grade of the Ph.D. Dissertation.
