2015-2016 Academic Year
The Doctor of Philosophy in Civil and Infrastructure Engineering (CIE) was created to prepare students for advanced leadership positions in research and development in the public or private sector, academics, or government. Students may elect to study in the areas of: environmental and water resources engineering, geotechnical engineering, structural engineering, or transportation engineering. Admitted students will complete both required and applicable course work in their technical interest area based on a plan of study prepared with a doctoral advisor. They will take qualifying exams that assess student's breadth of knowledge at the graduate level and competency to conduct research. They will form a doctoral committee and prepare and defend a dissertation proposal leading to PhD candidacy. Finally, they will conduct original scholarly research and prepare, then defend a doctoral dissertation. Both part-time and full-time study is available.
- All general George Mason University and specific Volgenau School admission requirements (including deadlines) apply. In addition, all applicants, including Mason undergraduates, must submit the following:
- Official transcript of undergraduate and graduate course work
- For applicants whose official language is not English, official TOEFL scores which meet the minimum requirements set by the Volgenau School
- Three letters of recommendation from individuals knowledgeable about the applicant's professional or academic work (at least two of the letters should be from individuals with doctorates)
- Recent professional résumé
- Substantial statement of interest that includes a description of the specific area of proposed dissertation research, contacts the student has made with potential faculty advisors, and an explanation of career and research goals
Admission decisions will be based on the student's qualifications and the availability of a faculty advisor in their proposed area of research. The application materials will be reviewed by the department doctoral committee and decisions made with input from appropriate faculty members.
Financial support for outstanding applicants is available in the form of fellowships as well as research and teaching assistantships. For best consideration, applicants are encouraged to apply early and to contact potential faculty advisors to express interest in support.
Reduction of Credit
Students must complete a minimum of 72 graduate credits, which may be reduced by a maximum of 24 credits from a completed master's degree in civil engineering or other related fields. Reduction of credit requires the approval of the program director or designee and the dean or designee of the school. They determine whether the credits are eligible for reduction of credit and applicable to the degree program and the number of credits to be reduced.
The PhD in Civil and Infrastructure Engineering requires 72 graduate credits, including 48 credits of graduate coursework and 24 credits of research. Admitted students are expected to hold a Bachelor of Science in Civil Engineering or degree in a closely-related science field.
Exceptionally-qualified students without a related bachelor’s or master’s degree may be admitted provisionally and required to take additional undergraduate- and graduate-level articulation courses prescribed by the doctoral committee, which will not count towards the PhD degree.
The following degree plan is based on a student who receives a full 24 credit reduction. Students who do not receive a full credit reduction should choose additional credits in consultation with their advisor.
Doctoral Coursework (24 credits)
A minimum GPA of 3.50 is required and no C grades are allowed for the 24 credits earned beyond the MS. A detailed plan of study will be prepared for each student upon acceptance into the program and in consultation with the faculty advisor, which outlines all course requirements to include:
Required Courses (6 credits)
The following must be completed while in residence in the program.
- CEIE 800 - Civil, Environmental, and Infrastructure Engineering Colloquium (1 credit) (must be taken at least twice)
- CEIE 990 - Civil and Infrastructure Dissertation Topic Presentation (1 credit)
- And one of the following three courses:
- CS 504 - Principles of Data Management and Mining (3 credits)
- OR 640 - Global Optimization and Computational Intelligence (3 credits)
- CSI 690 - Numerical Methods (3 credits)
Courses chosen with Advisor (18 credits)
Remaining courses, especially in the student's technical interest area, will be chosen in consultation with his or her advisor. No cross-listed courses may apply to the degree.
The PhD qualifying exam is offered twice a year prior to the start of the fall and spring semesters. The qualifying exam is intended to test students' breadth of knowledge at the MS level in their research area and to evaluate readiness for research. Students entering with a MS degree are required to attempt the qualifying exam within 18 months of admission to the program. Students entering without a MS degree must attempt the qualifying exam within two years of admission to the program.
The qualifying exam consists of one written exam and one oral exam in the student's primary research area. The available examination areas include:
- Area A: Environmental Engineering
- Area B: Geotechnical Engineering
- Area C: Structural Engineering
- Area D: Transportation Engineering
- Area E: Water Resources Engineering
The requirements of the written exam (deadlines for exam request, list of topics, allowed aid sheets, calculator policy etc.) are posted on the department's website. The oral exam is conducted by an examining committee of three CEIE graduate faculty, of whom two must be in the student's research area. Students give a five minute research presentation, and answer questions from the examination committee about the written exam, the research presentation and other related topics.
Students who receive an overall passing grade form a dissertation committee and register for CEIE 998 - Doctoral Dissertation Proposal. Students who receive an overall failing grade may petition to repeat the exam. If granted, the second attempt, which includes both the written and the oral exam, must be completed within one calendar year. The petition to repeat the exam must be received within one month of the first exam attempt. No more than two exam attempts are permitted. Students who do not receive an overall passing grade are terminated from the program.
Dissertation Research (24 credits)
Students become eligible for CEIE 998 upon passing the qualifying exam (preceding section). Upon admission to candidacy, which requires satisfactory preparation and defense of a dissertation proposal, students may register for CEIE 999.
- CEIE 998 - Doctoral Dissertation Proposal (1-12 credits) (must complete a minimum of 12 credits)
- CEIE 999 - Doctoral Dissertation (1-12 credits) (must complete a minimum of 12 credits)
A dissertation committee (separate from the examination committee) is formed upon successful completion of the qualifying exams. The student, in consultation with their advisor, shall select at least three full-time CEIE Department faculty members, and at least one committee member from Mason outside the CEIE department. At least three members of the committee are to be members of the Mason graduate faculty. All committee members must hold earned doctorates and possess applicable knowledge and experience in the student's chosen topic. The CEIE Department Chair must approve the composition of the dissertation committee. Additional committee members from outside Mason (e.g., from industry, other institutions, etc.,) may be appointed if approved by the majority of the CEIE faculty. The committee must be formed and approved before admission to candidacy (described in the next section) and before registering for CEIE 999 Dissertation Preparation. Substitutions to the dissertation committee are allowed with the approval of the CEIE Department chair.
Dissertation Proposal Preparation and Advancement to Candidacy
After successfully passing the qualifying exams and forming of a dissertation committee, the student may register for CEIE 998 research credits and begin preparation of the dissertation research proposal. At least 12 credits of CEIE 998 are required during which the student will consult with his or her advisor on the selection of an original scholarly topic and preparation of a formal research proposal. Students are also encouraged to register for the required CEIE 990 Civil and Infrastructure Dissertation Topic Presentation course during this time. Students must schedule a formal proposal defense (also known as the research competency exam) with all members of their chosen committee present. This cannot be done before successful completion of the qualifying exams. Committee members should receive printed copies for the final proposal not less than two weeks prior to the scheduled defense date.
The research competency exam (proposal defense) includes the written proposal and a presentation of the planned dissertation research. The dissertation proposal defense shall not include already completed research. The dissertation proposal defense is the main opportunity for the committee to provide input and for the dissertation committee members to examine the student’s knowledge in higher-level course work and familiarity with existing and emerging research related to the student’s research area. After the student’s presentation, and after private deliberation, the committee makes a pass/fail determination that is given to the student by his or her advisor.
Students who pass the research competency exam are admitted to candidacy and become PhD Candidates. Students who do not pass the exam may, in consultation with their advisor, schedule a second exam within 120 days of receiving notice of the first exam result. Students who do not re-schedule and successfully pass the research competency within this period are dismissed from the program.
Dissertation Research and Defense
On successful completion of the dissertation proposal, students are to conduct original research under the guidance of their dissertation director and dissertation committee members. Students are not to schedule their dissertation defense sooner than two semesters after a successful proposal defense. The dissertation must represent achievement in research, must be a significant contribution to the field of civil engineering, and should be deemed publishable in refereed journals. When the majority of the research has been completed, the candidate is to submit a written draft of the dissertation to the doctoral dissertation committee and schedule an oral pre-defense with the doctoral dissertation committee. The pre-defense is to be attended by the doctoral dissertation committee and the department chair.
A final, public, oral defense may be scheduled no sooner than one month after the conclusion of the pre-defense, which will allow for a minimum of two weeks to advertise it broadly. The final defense is to be attended by the doctoral dissertation committee and the department chair. On successful completion of the oral defense, students must submit a final dissertation that meets the guidelines specified by the Guide for Preparing Graduate Theses, Dissertations, and Projects. If the student fails to defend the dissertation successfully, the student may request a second defense following the same procedures as the initial defense. This request has no time limit, other than the general time limits for the doctoral degree as per Mason policy. An additional pre-defense is not required; however, the student is strongly advised to consult with the committee before scheduling the second defense. If the student fails on the second attempt to defend the dissertation, the student will be dismissed from the PhD program. Following a successful public defense and completion of the final form of the dissertation, the dissertation committee recommends the candidate for the degree of Doctor of Philosophy.
All PhD students are encouraged to participate in teaching activities in consultation with their major advisors. Teaching opportunities include presenting lectures, conducting recitation sessions, serving as a teaching assistant, working as a laboratory assistant, participating in teaching workshops, preparing course materials, and other related activities approved by the student’s advisor.
Total: 72 credits
Doctoral students complete both required and elective coursework in their technical interest area based on a plan of study prepared with their PhD advisor and they gain early experience by teaching undergraduate-level courses.
The PhD requires specialization in one of the areas offered by the department, which are:
- Environmental engineering
- Geotechnical engineering
- Structural engineering
- Transportation engineering
- Water resources engineering
Both part-time and full-time study is available. Full-time students typically complete the program in three to five years, depending on their background and the nature of their research.
