Ph.D. Degree Program

The Ph.D. degree is awarded by the Graduate School of Arts and Science rather than by the School of Engineering and Applied Science; as a result, there are certain differences in the specifications for written dissertation and certain formal requirements to be met. Information on these is available from the Office of the Associate Dean for Graduate Education of the School of Engineering and Applied Science. All applications for the Ph.D. degree are made through the Graduate School of Arts and Sciences. Students accepted into the Ph.D. program need not complete a masters degree.

The minimum time required for the Ph.D. degree for a student entering with an M.S.E. or equivalent degree is two calendar years. The time for the completion of a combined M.S.E. / Ph.D. is typically between four and six years.

Ph.D. Program Requirements
Students must complete each of the requirements outlined above within the time frames outlined above. If a member of any of the committees described above is unavailable for an examination, the advisor will recommend an appropriate substitute committee member. Substitute committee members must be approved by the Graduate Group Chair. In rare cases, the Graduate Group Chair may approve rescheduling one of the examinations based on incompatibilities in the schedules of the committee members.

1. Coursework: To qualify for the Ph.D. program, all students must complete 7 approved courses in their first year. Typically, four of these will be taken in the first semester and three in the second. Three core courses are required for all students (no exceptions): MSE 520 Structure of Materials, MSE 530 Thermodynamics & Phase Transformations, and MSE 540 Phase Transformations. Students must maintain a grade point average (GPA)above 3.25 for the first year and above 3.0 for the remainder of their coursework. Non-core courses may be selected from offerings within the MSE department and other departments in SEAS, as well as the physical biological, and mathematical Sciences. A student transferring from other graduate programs can only include transferred courses with the approval of the MSE Graduate Group Chair. Students should register for one research credit in their second semester reflecting the expectation that they participate in research. Students are required to take at least 10 graduate level courses (500 or greater). Within the ten courses, students are expected to include courses outside of their research area to gain a broader understanding of materials science and engineering. Doctoral students with a Master's degree may transfer up to eight credits as course units to the Ph.D. program upon the approval of the Graduate Group Chair. However, a maximum of five transferred courses count toward the 10 courses required for the Ph.D. program.

2. Qualifying Exam (Paper and Oral): In Year 1, in addition to the coursework, Ph.D. students must also pass the qualifying examination. This examination is held at the end of May after the second semester and tests the student’s potential for identifying and investigating significant research questions and the depth of their understanding and intellectual integration of the materials covered in the 7 courses. As part of this examination, the student will write an original paper that consists of an analysis and critique of one or more articles published in the scientific literature typically in the general area of the student’s research focus area. The qualifying exam paper will be orally presented and defended to a committee of three faculty members. The student must prepare (1) an abstract of their qualifying exam paper (no more than 250 words) and (2) a separate paragraph describing their research progress in the first year (no more than 250 words). The abstract (1) should describe the proposed area of focus for the qualifying exam paper, the topic(s) of the journal articles to be reviewed, and the general nature of the proposed critique. Students must also include copies of the selected research article(s). The abstract must be submitted by the end of the first Friday of March. The student will be notified within 2 weeks whether the proposed literature article(s) is acceptable. If it is unacceptable, the students will be provided feedback explaining why the proposed articles(s) or other aspects of the abstract were not accepted. The qualifying examination paper must incorporate a thorough analysis of one or more important and significant research articles in the published scientific literature and include a proposed research plan. A typical qualifying examination paper will (1) identify the general research area, (2) summarize the main points of the article(s) and the student’s view of its significant contributions to the field, (3) identify issues that the article author(s) neglected or did not properly address, problems with the methodology, (4) how the student would address these deficiencies, (5) address these deficiencies would alter the data or their interpretation, and (6) identify appropriate next steps in the line of research discussed in the article. The qualifying examination paper should be approximately (but no more than) 20 single-spaced pages (including figures) with references (no page limit), plus a one-page (single-spaced) description of their research progress to-date. The qualifying examination paper must be submitted no later than two weeks after the end of the Spring Term finals period.

The oral section of the qualifying examination will take place approximately one week after the scheduled
submission of the qualifying examination paper. During the oral examination, the student will (1) present their qualifying exam paper (30 minute maximum) and (2) present their research progress (15 minute maximum). The qualifying examination committee will assess the student’s ability to debate the fundamental background, significance, and results of the research article(s) and the research plan, illustrate its importance within the research field, and demonstrate that they are able to integrate the knowledge gained in their coursework. The qualifying examination committee will consist of three members of the Graduate Group and the student’s advisor will not be present. Any student who fails the oral qualifier has the option of retaking the examination within six weeks of their first attempt. Students failing the retake are not be permitted to continue in the doctorate degree program and have the option of entering the Masters degree program.

3. Dissertation Committee Composition and Meetings: The Dissertation Committee provides the student and advisor with additional sources of information, guidance, and criticism of the research project, and reviews student progress in the Research Proposal Examination, 4th Year Research Update, the Dissertation Defense and other times as the student or advisor may request. Each student in the doctoral degree program will have a Dissertation Committee of at least four members, including the advisor. At least half of the members of the Dissertation Committee must be members of the MSE Graduate Group (at the time of their appointment to the committee). One member of the Dissertation Committee (other than the Advisor) from the Standing Faculty in the MSE Graduate Group will be appointed as Chair of the Dissertation Committee. If the Chair of a Dissertation Committee leaves the Standing Faculty before the dissertation is completed, then a new chair from the Standing Faculty in the MSE Graduate Group must be appointed as chair. The membership of the Dissertation Committee (including members from outside the MSE Graduate Group) must be approved in writing by the MSE Graduate Committee Chair.

The Dissertation Supervisor is the person primarily responsible for overseeing the student’s dissertation research. A student may have both a Dissertation Supervisor and a Dissertation Co-Supervisor, or two Dissertation Co-Supervisors, if that responsibility is shared equally. Dissertation Supervisors and/or Dissertation Co-Supervisors, must be members of the Standing Faculty at Penn, with special exceptions that must be approved by the Graduate Group Chair. A member of the Associated Faculty (such as Research Faculty or Adjunct Faculty) may be permitted to serve as a Dissertation Supervisor with prior approval of the Vice Provost for Education on a case by case basis. The MSE Graduate Group Chair may petition the Vice Provost for Education, in advance, for an exception. In such cases, a member of the Standing Faculty in the MSE Graduate Group must be appointed as the Dissertation Committee Chair.

4. Second Year Progress Update: In Year 2, doctoral degree students must submit an Annual Dissertation Research Progress Report (one page, single-spaced, one figure), signed by the advisor, to the Graduate Group Chair. This progress report should include background, motivation, research progress, and a brief summary of future work. This update is due December 1. The advisor must approve the proposal by the end of December.

5. Third Year Research Proposal: In Year 3, doctoral degree students must submit a research proposal to the Graduate Group Chair and their Dissertation Committee. The proposal (20 pages maximum) should describe the focus of the student's thesis project, identify the technological and scientific importance of the work, outline the theoretical or experimental approach to be followed, and include their results to date. The proposal is due
December 20. Near the end of the following January, an oral examination will be scheduled. The exam will be conducted by the Dissertation Committee. The purpose of this exam is to evaluate the motivation and capability of the student for their research, based on his/her demonstration of in-depth understanding, independence of thought and progress towards completing his/her PhD. The committee will also provide advice and/or suggestions for future directions. The student will be expected to make a presentation (30 minute maximum) on their thesis research followed by discussion with the Dissertation Committee. If the committee finds the student is seriously deficient in their progress and/or capability to conduct the independent research, the committee may recommend a second oral examination within 3 months. Continuing in the PhD program requires committee approval of the research proposal.

6. Annual Research Update Beyond Year 3: Near the end of January of Year 4 (and subsequent years if a student has not completed all requirements for the PhD degree), a 15-minute student oral presentation will be scheduled with the Dissertation Committee. The students will discuss their progress (e.g., significant discoveries, publications, proceedings, and abstracts) and anticipated work for completion of their doctoral thesis. The committee will review the doctoral degree student’s progress and determine whether the student’s progress is sufficient in all aspects. If the committee decides that the student is seriously deficient in research progress, it will recommend a follow-up oral presentation within 3 months from the first review.

7. Dissertation and thesis defense: When the dissertation work is completed to the satisfaction of the advisor, the student prepares a written dissertation according to the specifications available in the departmental office or Deputy Dean. The Examination Committee is normally the same as the Dissertation Committee; deviations from this norm must be approved by the Graduate Group Chair. Copies of the dissertation must be submitted to the members of the Examination Committee ten days before their defense, after which the student will defend the dissertation in an oral examination before the committee. Students schedule the time and location of their thesis defense and are asked to inform the time and place of the examination are announced in advance, and the dissertation presentation and initial question-and-answer portion of the exam are open to the public. The final portion of the examination will be restricted to the student and the Examination Committee. However, this part of the examination may also be public if unanimously approved by the Examination Committee. If the dissertation and the defense are accepted, the advisor and the Graduate Group Chair will sign the Ph.D. Degree Certification form, which is then submitted to the Deputy Dean for further action. The committee may require changes in the dissertation, and, in exceptional cases, a second dissertation defense.

8. Seminars: All doctoral degree students are required to attend all departmental seminars; persistent absences may result in removal from the graduate program.

Modifications and Exceptions

Requests for exceptions to or modifications of these requirements must be made in writing to the Graduate Group Chair. Requests should be discussed in advance with the advisor, and should include the reasons for seeking the change. Petitions to modify requirements of the University or of the School must be further approved by the Graduate Affairs Committee of the School.
