The Information Technology (INFT) PhD is a signature degree of the College of Engineering and Computing.  The program focuses on the science, engineering, and technology of information processing, an area of study ripe for innovation in a world driven more and more by data.  The PhD in INFT accommodates rigorous and cross-disciplinary PhD study that does not fit with PhD program requirements of a single VSE department.   The PhD in INFT includes several concentrations to provide program focus.


Admission is competitive.  An undergraduate degree in an information technology-related area, such as engineering, computer science, operations research, mathematics, or the physical sciences is typically required for admission. The undergraduate preparation should include, at a minimum, calculus, differential equations, linear algebra, discrete structures, probability, and statistics, in addition to computational proficiency, including experience with a variety of languages and computer hardware.  Additional requirements depend on the proposed study focus.  

Most successful applicants complete their master's degree before admission with a minimum GPA of 3.5 out of 4.0. Applicants can also be considered directly from their undergraduate studies with a minimum GPA of 3.25 out of 4.0.  

Applicants wishing to switch fields from non-information technology-related academic backgrounds, especially those with extensive work experience in information technology, are encouraged to discuss opportunities for study.  This path into the Information Technology, PhD program typically requires academic preparation in the formal framework and underpinning theory of information technology.  Those applicants are referred to the College of Engineering and Computing (CEC) departments offering the concentrations and courses of greatest interest, prior to application.

Applicants are required to submit: an online application for admission, undergraduate and graduate transcripts from previous colleges and universities, three letters of reference (preferably from college instructors), goals statement and a résumé.  Applicants are also required to submit a brief personal goals statement including the proposed research areas of interest.  Admission for cross-disciplinary Information Technology, PhD study will depend on alignment with CEC faculty research expertise.  

International applicants are referred to the university’s English Proficiency Requirements.  In addition, international transcripts must be translated and evaluated (course-by-course preferred) by a member of the National Association of Credential Evaluation Services (NACES). Transcripts can be evaluated by George Mason University at no extra cost to the applicant. Please review George Mason University's Policy on International Transcript Submission. Applications must be completed and submitted before an admission decision is made.


The general doctoral requirements of Mason apply to this program.

Plan of Study

All INFT PhD students require a faculty advisor to guide and oversee their academic progress and research.  Students are strongly encouraged to select a study concentration by the end of their first year.  Concentration areas are based on broad areas of faculty expertise.  Students who do not choose an established concentration are still constrained by existing faculty research expertise and faculty willingness to accept new doctoral students. 


Available Concentrations

Specialized Coursework

Each student works with his or her faculty advisor/dissertation director to develop a plan of study.  Successful coursework completion includes:

  • A cumulative GPA of 3.50 in courses included on the plan of study, and all grades must be a B- or better.
  • At least 12 credits on the plan of study must be courses numbered 700 or higher. No 500 level courses are permitted except for fundamental knowledge courses.

Breadth Requirement

To satisfy the breadth requirements of the PhD INFT, a student must demonstrate his/her proficiency in the foundational knowledge specific to her/his program of study. This is satisfied through completion of two Fundamental Knowledge Courses (FKC), and two Qualifying Exams (QE).

Students must complete the breadth requirements within the following time limits:

  • Students who enter the program with a 24-30 credit reduction from a prior Master’s degree must satisfy all breadth requirements no later than twelve months following the end of their fourth semester in the program.
  • Students who enter the program with a reduction of less than 24 credits must satisfy all breadth requirements no later than twelve months following the end of their sixth semester in the program. 

In both instances, these time limits include all attempts at the Fundamental Knowledge courses and the Qualifying Exams. Time limits, AP.6.10.1., apply to all PhD INFT students, regardless of their part-time or full-time study status. Failure to satisfy all breadth requirements by the specified time is cause for termination from the PhD INFT program.

Fundamental Knowledge Course (FKC) Requirement: 

Fundamental Knowledge courses are listed in the study guide maintained by the College of Engineering and Computing of Graduate Studies (CECGS). Fundamental Knowledge courses must be approved by the faculty advisor/dissertation director; must be specific to the student’s program of study; and must be submitted to CECGS. These courses may be used as credit toward the student’s plan of study.  

Students must earn a grade of A- or better in both Fundamental Knowledge courses on their first attempt to satisfy this component of the breadth requirement.

Qualifying Exam (QE) Requirement:

Qualifying Exams are listed in the study guide maintained by the College of Engineering and Computing Office of Graduate Studies (CECGS). Selection of Qualifying Exams must be approved by the faculty advisor/dissertation director; must be specific to the student’s program of study; must not duplicate the bodies of knowledge of the student’s Fundamental Knowledge courses; and must be submitted to CECGS.

Qualifying Exams are offered twice a year, just before the fall and spring semesters. Each exam is allocated two hours and graded on a pass or fail basis. Students must take all required QE's in their first attempt. Students failing one or both of their QE's on the first attempt are required to retake the QE they did not pass the next time the QE's are offered. Students failing QE's may not subsequently satisfy the breadth requirement by completing Fundamental Knowledge courses.

Comprehensive Exam

The comprehensive exam is an oral exam taken after students have satisfactorily completed all coursework requirements in their approved plan of study, passed the breadth requirement, inclusive of FKC and QE, and after the student's dissertation committee has been formed. To initiate the Comprehensive Exam process, the student meets with their dissertation director to prepare an Oral Comprehensive Exam Request form.  This Request must be approved by their entire dissertation committee and forwarded to CECGS for final approval. The permission form must be submitted with:

  • a one page description of the intended area of research; and
  • a reading list on which the student will be examined.

The reading list should include articles and/or books that cover the fundamentals, state-of-the-art, and tools needed to perform research in the intended area.

The objective of the Comprehensive Exam is to allow the dissertation committee to assess the student’s readiness to complete doctoral research in the chosen area of concentration. The duration of the oral exam is typically two hours.  The comprehensive exam must be attempted for the first time no later than one year after starting the IT 998 Doctoral Dissertation Proposal sequence.

Students who fail the exam are permitted to retake it once. Failure in the second attempt will result in termination from the program.

Dissertation Proposal Presentation

After successful completion of the Comprehensive Exam, doctoral students prepare a written dissertation proposal to present to the dissertation committee. Students must enroll in IT 998 Doctoral Dissertation Proposal to complete this effort. While in the IT 998 Doctoral Dissertation Proposal sequence, the student should enroll in IT 990 Dissertation Topic Presentation. The dissertation proposal presentation must be at least one week after passing the comprehensive exam.

Advancement to Candidacy

After successfully completing the dissertation-proposal requirement, the student is formally admitted as a candidate for the PhD degree and must begin and maintain continuous registration in IT 999 Doctoral Dissertation. The application for advancement candidacy is submitted to CECGS on a standard Registrar form.

Once enrolled in Dissertation Research, students should maintain continuous registration in IT 998 Doctoral Dissertation Proposal until advancement to candidacy and must maintain continuous registration in IT 999 Doctoral Dissertation until the dissertation is complete, successfully defended and approved by the dissertation committee, and has been successfully submitted to the library. Continuous registration does not include summers, except for when conferral occurs in August. For more information please see AP.6.10.6.

Faculty Advisement

On admission to the program, students are assigned a temporary faculty advisor aligned with the research area that the student identified in their application. The temporary faculty advisor advises on and approves the student’s initial course selection. 

Ultimately, all INFT students require a dissertation director who will direct the student’s PhD studies, including the dissertation research.  This arrangement, by mutual consent of the student and dissertation director, should be agreed on before the student begins their research. Topics of potential research are determined by the expertise and interests of the faculty.  The student is responsible to identify, communicate and offer proof of their research skills to the faculty under whom they wish to work.  A student’s engagement, excitement, commitment, relevant academic and non-academic background, and initiative are all attributes a potential dissertation director will consider before making the decision to formally commit.  The university does not manage this matching process, nor can it compel any faculty member to undertake this role for a student.

Dissertation directors and their students should arrive at an understanding of the dissertation director’s expectations.  This must include a clear understanding of the research topic and the courses the student must complete in support of that research.  It should also include, at a minimum, a timeline for the overall planned program of study, expectations regarding technical publications and presentations arising from the research, availability of graduate student support, advising style, and the location where the student will conduct the research and when.  A successful dissertation depends on shared understanding. 

Students have the right to change dissertation directors.  Changing dissertation directors slows academic progress, and students are discouraged from changing more than once, since demonstration of satisfactory progress on the PhD is one criterion for continuation in the program.  Dissertation directors also have the right to decline or to discontinue supervising students. 

Dissertation Committee

After a student and their dissertation director agree to work together and file this information with the College of Engineering and Computing Office of Graduate Studies (CECGS), the dissertation committee can be formed.  The dissertation committee includes the dissertation director, who must be a member of the Mason graduate faculty, and at least three other people from the Mason graduate faculty. In addition, the dissertation director must have at least a 50% appointment in CEC. This rule does not apply to a co-director. At least three dissertation committee members must be from CEC, and at least two of the departments in CEC must be represented to meet expectations for interdisciplinary research.  Representatives from industry or government with key, related expertise may also be considered if they have been appointed to university graduate faculty status.

The dissertation committee administers the comprehensive exam, the dissertation proposal presentation evaluation, the dissertation predefense (if applicable) and defense by submitting the appropriate forms to CECGS.

Dissertation and Final Defense

With the concurrence of the dissertation committee and CECGS, students proceed with the dissertation research, during which time they must maintain continuous registration in IT 999 Doctoral Dissertation, (AP.6.10.6). Students are encouraged to draw on the expertise and guidance of their dissertation committee during their research, including submission of a draft dissertation to the committee members.  When the PhD student’s research is complete to the satisfaction of the dissertation director, the student may submit the written dissertation to the dissertation committee and engage in an oral predefense, which is encouraged, but not required. At the point when the dissertation committee believes the student has completed satisfactory research meeting their expectations for awarding a PhD, a final public oral defense may be scheduled allowing a minimum of two weeks for the defense notification as required by the University, AP.6.10.8. The entire dissertation committee and the associate dean must be present at the defense, unless an exception is approved by the associate dean of graduate programs in advance of the defense.

If the candidate successfully defends the dissertation, the dissertation committee and associate dean recommend that the final form of the dissertation be completed and the CEC faculty and the graduate faculty of Mason accept the candidate for the PhD degree. At that point, the student submits to the university library a final publishable dissertation that represents a definitive contribution to knowledge in INFT.

If the student fails to successfully defend the dissertation, the student may request a second defense, following the same procedures as for the initial defense. There is no time limit for this request other than general time limits for the doctoral degree (AP.6.10.1). Students are strongly advised to consult with their dissertation director and dissertation committee before scheduling a second defense. If the student fails on the second attempt to defend the dissertation, the student will be terminated from the INFT program.
