The program is designed so that the student is exposed to a breadth of knowledge through the program core and a depth of knowledge through the track core. The candidacy exam will have a written and an oral component. The written component will test the student on the fundamental knowledge at the advanced undergraduate level, whereas the oral component will test the student’s ability to conduct research in his/her area of interest. The following candidacy exam structure is followed:
- The student can take the candidacy exam no sooner than the second semester he/she is in the program and no later than the third semester he/she is in the program.
- The student will have to officially declare his/her intention to take the candidacy exam by the end of the semester prior to the semester in which he/she will take the exams for the first time.
- The student will have to attempt both components in the same semester, and will need to pass each of the components separately. If the student fails to pass one or more components in the first attempt, he/she will have to retake those components in the next semester. Failure to pass the exam in two attempts will result in dismissal from the program, pending review of the Engineering Science and Systems Governance Committee. This review will be completed and a decision conveyed to the student by the end of the academic year when he/she has taken the exam.
- A sample written exam for each track and a sample research topic for the oral exam will be on file with the graduate coordinator. The students will have access to the sample exam for the purposes of familiarizing themselves with the written component of the candidacy exam.
- Decisions of the Track Candidacy Exam Committee will be supported by a minimum of 2/3 majority of the committee members present and will be any one of the following:
ii. Pass with remedial course work
iii.Fail; in this case, the student will retake the oral component in the next semester on the same research topic; a new report will have to be submitted by the student prior to retaking the oral exam.
The written exam for each track will be one four-hour exam, and there will be only one exam for each track.
The syllabus of the written exam will be identical for the fall and spring semester exams in a given academic year, and will be published at the beginning of the spring semester of the prior academic year. The study materials for each track will also be recommended.
The student will have passed the exam if her/his overall grade in the written exam is 70% or higher.
The oral exam for each student taking the exam will be of one-hour duration.
Student will be given a research topic on which to submit a written report. This report shall be submitted no later than one month from the date the student was assigned the topic.
The student will be provided with a template. The same template will be used for all the tracks. The submitted report will have to adhere to the guidelines of the template.
Using the written report as the basis, the student will be orally tested by the Track Candidacy Exam Committee. The oral exam will be scheduled no earlier than two weeks after the student has submitted the report.
At least two years prior to the dissertation defense, candidates must present their research proposal to their Doctoral Dissertation Committee. At the completion of the examination, the Doctoral Dissertation Committee will vote to either pass or fail the student. Students who fail the proposal defense will have to repeat the defense within a semester of their first attempt. If the student fails the proposal defense for a second time, he/she will be dismissed from the program, pending review of the Engineering Science and Systems Governance Committee.
In order to complete the requirements for the doctoral degree, students will prepare and successfully define a written dissertation in accordance with the format and procedures dictated by the Graduate School. Students must orally defend their completed doctoral research to their Doctoral Dissertation Committee. At the completion of the examination, the Doctoral Dissertation Committee will vote to either pass or fail the student. If two or more negative votes are cast by the committee members, the student is considered to have failed the exam and will be dismissed from the program, pending review of the Engineering Science and Systems Governance Committee.
Doctoral Dissertation Advisor
A student admitted to the doctoral program can declare an advisor, with advisor’s approval, no earlier than the second semester that he/she is in the program. The student is required to meet with faculty eligible to mentor him/her as dissertation advisor before the student can declare the dissertation advisor. As part of the process, the student will have to interact/work with at least three faculty members.
Doctoral Dissertation Committee
The Doctoral Dissertation Committee can be constituted once the student has declared his/her doctoral dissertation advisor, and no later than the second semester that the student has been in the program. The committee will include a minimum of five members and a maximum of seven members. At least four members have to be Engineering Science and Systems program faculty. The committee can have one or more external members who are not Engineering Science and Systems program faculty. If the dissertation advisor and the doctoral student are affiliated with different tracks, it is required that at least one Engineering Science and Systems program faculty in the committee belong to the student’s track.
Courses in the Engineering Science and Systems Doctoral Program
The catalog description of the program core, track core and elective courses, and the dissertation research courses that are part of the Engineering Science and Systems Doctoral Program, is provided in the “Systems Engineering,” “Computer Science,” “Information Science,” and “Information Quality” sections of this catalog. Other courses may be approved in consultation between the student and his/her Doctoral Dissertation Committee.
Up to twelve credit hours may be granted to the student for completing equivalent graduate coursework at other institutions. Such credit must be exclusive of thesis or other exit project credits, be no more than five years old at the time of transfer, and must have a letter grade of B or better. In some cases students may be required to balance their transfer credit with a corresponding increase in research hours. Students interested in requesting a credit transfer should discuss the request with their doctoral dissertation advisor and appropriate track coordinator. The request must also be approved by the Engineering Science and Systems graduate coordinator and the dean of the Graduate School before the transfer of credit can be granted.
