The exam consists of the oral defense of a written research proposal developed by the student. As a first step the student will develop two pre-proposals, each on a different research topic. One of these will be developed into a complete proposal to be defended by the student before their examination committee.
Timing. Students are expected to take the Oral Comprehensive Exam (OCE) during the fall semester of their third year of graduate school. The first step in the process is the submission of the pre-proposals, which are due by Oct. 1. A special permission from the Graduate Affairs Committee is required in advance if a student is unable to submit the pre-proposals in time. Permission must include an explanation for the delay and a proposed timeline for submitting the pre-proposals. Graduate Affairs Committee will evaluate special circumstances, such as medical leaves, department transfers on a case-by-case basis. OCE can be taken earlier if so desired and it can be arranged.
Committee Membership. The Director of the Microbiology Graduate Program must approve the examination committee. The examination committee will consist of at least four members and the student's major advisor. The chair of the committee must be a member of the Department and cannot be the student's major advisor. At least three members of the committee must have primary appointments within the Department and at least one member must be from outside the Department.
Pre-Proposal. To begin the process students will write two pre-proposals, neither of which can be related to research topics ongoing in the lab they have joined. If there is some question the student should consult their committee chair. The pre-proposals and the final proposal are to be based upon original ideas of the student and are to be written independently (consultations with other students or faculty who are not committee members are encouraged). Each pre-proposal should be limited to three pages, including figures and tables, but not including references. Each page should be single-spaced, with a left/right/top/bottom margin of 3/4", and a font size of 11 (Arial). The emphasis of the pre-proposals is to provide a sufficient background to frame the hypothesis. In addition, a brief outline of the experimental strategy should be included. This outline should include the specific aims. Be sure not to propose too many aims so that each aim can be explored in depth. Two or three specific aims are standard.
The exam committee will determine:
The Committee will meet without the student present and make one of the following decisions:
If neither pre-proposal is suitable, the chair of the committee will summarize the suggestions of the committee and prepare a written statement. The committee's request must be honored within 14 days of the request. When the committee re-reviews a pre-proposal, the committee can either accept the proposal or allow another 14 days to continue to revise the proposal. If the pre-proposal is not acceptable, the student will be dismissed from the Ph.D. program.
Proposal. The student will expand the pre-proposal into a full length proposal. The full proposal is due within 60 days of notification that a pre-proposal is acceptable. The proposal should follow the NIH guidelines of an R21 application, except that it can be expanded to 12 pages, excluding the cited references. An excellent resource for grant-writing tips can be found here. The proposed research should be capable of being completed by a team of three graduate students in three years. Be sure to consider the expected results as well as alternate results for each experiment. Consider the follow-up experiments for each possible result. Consider alternate approaches in case the first approach fails.
Recommended lengths for each section
When the written proposal is prepared, a hard-copy is distributed to each member of the committee (an electronic copy may be submitted if agreed upon by each member of the committee). The committee will discuss the proposal (either in a meeting or via e-mail/teleconference/video conference) to decide whether the proposal is suitable for the examination.
The committee will make one of the following decisions:
Examination. When the committee agrees that the proposal is suitable for examination, the student will schedule the examination. At this point, (i.e. about 4 weeks before the examination), the Departmental Graduate Studies Director needs to be supplied with (i) the scheduled date of the exam, and (ii) a list of the faculty serving on the examination committee. (This time frame is required by the Graduate Studies Office to complete the required paperwork.)
The examination will begin with a 15-minute presentation by the student that introduces the biological problem, briefly outlines the specific aims and summarizes the approaches to answer the aims. This presentation is followed by a question and answer period. The questions from the committee are to be based on the proposal and any background material, techniques, and concepts that are relevant to the proposal. If the exam continues past three hours, the student has the right to terminate the questioning without negative consequence on the committee's decision. After the examination, the student will be excused from the room while the committee deliberates.
The committee has the following options:
Dismissal from the Ph.D. Program. If at any stage, the committee decides that a student shall be dismissed from the Ph.D. program, the student may be allowed to continue to work toward a Master's degree if mutually agreed upon by the student and the committee and support is available from their advisor.
The student is encouraged to meet with the Chair of the examining committee for procedural advice at any time during preparation of the pre-proposals or full proposal.
Format for Committee Meetings. A cumulative report will be prepared that will summarize the background for the project, the student's progress, and the committee's recommendations throughout the student's tenure in the department. The report will be distributed to the committee no less than one week prior to the committee meeting. For the first thesis committee meeting (Spring, year 3), students will prepare background information of the project (1 page). Students will also prepare a ½ page summary of their progress toward the completion of the project. After the meeting, the chair of the dissertation committee will add summary of the committee's recommendations to the report and distribute the report to the student, the student's mentor, and the department file. In preparation for each subsequent meeting, students will add a ½ page progress report to the report from the previous meeting. After each meeting, the chair will add the committee's recommendations.
Dissertation Committee Membership. The thesis committee will consist of at least five members. The chair of the committee must be a member of the Department and cannot be the student's major advisor. A majority of the committee must have primary appointments within the Department and at least one member must be from outside the Department. The committee must be approved by the Director of the Microbiology Graduate Program. The dissertation committee must meet a minimum of three times, unless waived by the Director of the Microbiology Graduate Program.
Defense Committee Membership. The defense committee will consist of the dissertation committee and will meet only when the thesis committee approves the student's intent to defend. The chair of the defense committee is the student's mentor. The defense committee must pass the student prior to the scheduling of the public defense. Note that the Graduate School requires a minimum of 3 weeks (21 days) notice to complete the paperwork.
