Two exams are required by the Graduate School as benchmarks toward the Ph.D. Information about the Graduate School requirements and guidelines for these exams, please see the Exams section of the Graduate School site.

A-Exam: Admission To Candidacy Examination

To qualify as a Ph.D. candidate, each graduate student must pass the Admission to Candidacy, or “A exam.”  This exam has both written and oral components.

Procedures

The A exam must be taken by September 30 of your third year. You should consult with your committee about an acceptable date/time and reserve a room.  You must file a Schedule of Examination Form (available from the Graduate School web site at http://www.gradschool.cornell.edu/?p=11) by June 15. The completed Schedule of Exam form for the A-exam must be filed with the Graduate School at least seven (7) days prior to the date of the exam. This form must be signed by all of the members of the Special Committee, the Director of Graduate Studies, and one of the GFAs. You should give a copy of the written proposal for your exam to each member of the examination committee at least a week before the oral exam.

If the exam is not taken by September 15 of your third year, your mentor must write a formal letter of explanation to the DGS, including the time when the exam will be taken.  A copy of the letter will go into your permanent file. Please note that not having obtained sufficient data is not an acceptable reason for delaying the A exam.

Course requirements for the major (including BioMG 7510 “Ethical Issues”), and all or most for the minor, should be finished by the time of the A exam.  Occasionally, the student and the Special Committee may feel an additional course is useful or important after the A exam and this may be recommended or required by the Special Committee.

Your examiners for the A exam are your Special Committee and one other member of the Cornell University faculty that you choose. (This person is usually, but not necessarily, from the Field of BMCB).  This fourth member should add breadth to the committee and have expertise closely aligned with the topic of your proposal.  They will read your proposal and participate in your A-exam, however, they should not sign the Schedule or Results of Exam forms as they are not a permanent member of your committee.

You should have your entire official committee sign the Results form before they leave the exam room. After obtaining your committee and the DGS’s signature, take the form to the GFAs for their signature and transmission of the form to the Graduate School. This form must be filed within three (3) business days of the date of the exam.

Note:  In accordance with the Code of Legislation of the Graduate Faculty, your A-exam is announced to – Field faculty. Please do not be concerned; Field faculty outside your, although free to attend by Graduate School rules, rarely, if ever do.

The Written Proposal

Your proposal will describe the research you intend to accomplish as a graduate student.  The proposal should be well-formulated and presented in sufficient detail that it can be evaluated for its scientific merit.  Include sufficient information to permit an effective review without readers having to refer to the literature. Brevity and clarity in the presentation will be considered indicative of an applicant’s approach and ability to conduct a superior project.  The proposal must be written following the format specified below.

  1. Abstract.  This is a summary of the proposed work, with enough of an introduction to allow someone not expert in the field to understand what is planned and to appreciate its importance.  This should be on a separate page and not exceed three vertical inches (single spaced).

Sections (2) through (4) are not to exceed 10 pages (single spaced), including all tables and figures.

  1. Specific Aims.  State the specific purposes of the research proposal and the hypotheses to be tested.  (Typically no more than half a page)
  2. Background and Significance.  Sketch briefly the background to the proposal. State concisely the importance of the research described in this application by relating the specific aims to field as a whole. Use this section to provide an account of any preliminary studies that might demonstrate the utility of the proposed project. (Typically about 3 pages)
  3. Research Design and Methods.  Provide an outline of (1) research design and the procedures to be used to accomplish the specific aims; (2) tentative sequence for the investigation; (3) statistical procedures by which the data will be analyzed; (4) potential experimental difficulties and alternative approaches that could achieve the desired aims. (Typically about 7 pages)
  4. Rigor, Transparency and Reproducibility: In keeping with the need for renewed attention to this topic, an additional (approximately ½ page) section should provide information pertaining to:
  1. Scientific premise: strengths and weakness of cited prior research that is crucial to the proposal;
  2. Scientific rigor: robust and unbiased experimental design and analysis (e.g., appropriate statistics and measures to avoid bias);
  3. Biological variables: consideration of relevant biological variables (in particular, sex as a biological variable in animal studies);
  4. Authentication of key biological and/or chemical resources (e.g., cell lines).

See additional detail on NIH proposal requirements in this domain.

  1. Literature Cited. List all literature references. Each reference must include the title, names of all authors, book or journal, volume number, page numbers, and year of publication. The reference should be limited to relevant and current literature. While there is not a page limitation, it is important to be concise and to select only those literature references pertinent to the proposed research.

Formatting: The application must be clear, readily legible, and conform to the following NIH requirements:

  1.  The height of the letters must not be smaller than 10 point; Helvetica or Arial 12 point is the suggested font (Arial 11 point will barely satisfy this requirement).
  2.  Type density, including characters and spaces, must be no more than 15 characters per inch (cpi). For proportional spacing, the average for any representative section of text must not exceed 15 cpi;
  3.  No more than 6 lines of type within a vertical inch;
  4.  Margins, in all directions, must be at least 1/2 inch.

Applicants should check the type size using a standard device for measuring type size rather than relying on the font selected for a particular word processing/printer combination. Figures, charts, tables, figure legends, and footnotes may be smaller in size but must be readily legible.

In preparing the application, use English and avoid jargon. If terms are not universally known, spell out the term the first time it is used, with the appropriate abbreviation in parentheses. The abbreviation may be used thereafter.

NOTE:  Use the single spacing formatting above to make sure that your final proposal with figures meets the requirements.  Send an electronic copy in this format to all your committee members.  But then print out hard copies in double space format to give to the committee, since this makes it easier for them to read and write comments.

The Presentation

You may use a PowerPoint presentation to support your written proposal.  You may only have five (5) printable slides with limited animation.  Up to five (5) additional slides containing supplementary data that is already in the written proposal may be added.  These should only be used for clarification if those experiments are discussed in the exam.

The Oral Exam

The oral component is a defense of this proposal and you can expect that the majority of questions will be directly or indirectly related to your proposal. The committee will likely ask you to explain, in more detail than the written format permits, background material and experimental protocols.

The committee will likely also ask broadly-based questions on basic concepts, to ensure you have strong command of foundational knowledge in BMCB and your minor area(s).  The committee member(s) representing the minor subject area(s) is particularly responsible to ascertain that you have achieved competency in that subject area.

In addition to the evaluation of your proposal, the A exam is the time when committee members will discuss and evaluate your course work as well as your performance in the laboratory.  Please bring a summary of the courses you have taken and grades earned to be distributed to the committee at the time of the A-exam.

Note that the Field recommendation is that during the exam, the mentor (thesis advisor) should not ask questions or make comments except when asked by other committee members or when clarification is needed.  The intended goal is to dissuade the mentor, who may have a vested interest in the outcome of the exam, from stepping in to justify the research or the particular experimental approach being used.  The student is expected to fully defend the proposal by themself.  However, the mentor should participate fully in the discussion of the student’s performance, after the student is asked to leave the room.  In making this recommendation, the Field is aware that the Special Committee may run the exam in whatever way it deems appropriate.

During the oral part of the A exam, the committee should devote at least 10 minutes to discuss Data Reproducibility. The 1/2 page section on the proposal should serve as a starting point for a more in depth discussion with the committee.

Possible Outcomes

The final outcome is determined by the Special Committee.  Examples below are not exhaustive and are provided to assist the student in their exam preparation.  Some factors that may be judged in evaluation of the A-exam are:

  • importance of the problem chosen
  • demonstration of a command of knowledge/research in the field.
  • evidence of creativity in formulating experimental approaches
  • feasibility of the proposed experiments
  • whether a range of different approaches are brought to bear on the problem
  • whether the scope of the proposed experiments is feasible for a 3-4 year project
  • adequacy of control experiments
  • clarity of the proposal
  • ability to deal with questions
  • communication / presentation skills/breadth of knowledge
  1. Unqualified pass.
  2. Conditional Pass.  This option will be exercised when the committee decides that some aspect of the proposal / defense needs to be improved.   In this case, the committee will specify the condition(s) required for the student to receive a pass and the timeline for fulfilling these conditions.  This must be done in writing and the Graduate School must be informed of the details.  This can be done in the form of an email from the Special Committee Chair to the Graduate School Student Services team (gradstudserv@cornell.edu).

Some examples of Conditional Pass:(a) The committee may specify that the proposal or that parts of it need to be revised within a certain time frame (i.e. improvement of writing; re-working of aspect of scientific research; addition of another section.  The extent to which the major professor wants to be involved in the rewriting is up to him/her.(b) The committee may specify that the student carry out additional literature review, e.g. weekly written report of a paper, participation in existing journal clubs.    This might be particularly helpful when the student appears to have weak command of the literature surrounding a particular area.(c) The committee may specify that the student complete a piece of research / a particular sub-aim within a certain time-frame.  This is particularly relevant when the committee has some concerns about the ability and/or motivation of the student to complete the PhD program.Typically a few students in each class receive a conditional pass on their A-exam.  If you are one of these, don’t be discouraged; simply work to fulfill the conditions that your committee sets, confident in the knowledge that fulfilling the conditions set will make your program stronger.

  1. Fail.  inadequate. In that case, the committee will usually recommend one of two actions.
  • If the committee has confidence in the overall ability of the student to complete the Ph.D. program, then they may recommend that the student retake the A exam.  In this case, they will specify whether an entirely new proposal on a different topic is to be written or whether they expect a major rewriting of the original proposal.  Note that the rules of the Graduate School specify that a second A exam cannot be scheduled earlier than 3 months after the first.If you do not pass your A-exam on the first attempt, don’t view it as the end of the world.  If your committee approves, just knuckle down and gear up for a re-take in three months.  There are plenty of students who easily passed on the second try and who did very well afterwards.
  • If the committee has serious concern about the motivation or ability of the student to complete the Ph.D. program, it could recommend that the student complete a piece of research, write a Masters-level thesis based on that work, and then defend that thesis.  

It is normal to be nervous about your A-exam.  We have these suggestions for you to help you feel confident, we suggest that

  1. Read several proposals written by former students.
  2. Read carefully the specifics on writing the proposal.
  3. Have a practice run.  You can do this by asking several students to read your proposal and then act as examiners during a mock 2-hour exam.

Please remember:  everyone in BMCB wants you to succeed.

Master’s Degree

The Field of BMCB does not have a formal Master’s degree program.  In cases in which a student decides that the BMCB Ph.D. program does not meet his or her needs, or in which a student is judged to be unqualified for the Ph.D. program, the Special Committee typically recommends that the student write and defend the research work done and receive a Master’s degree.  The requirements for a Master’s degree include the coursework normally taken by first-year students, at least two rotations, one semester of teaching, and a research-based thesis (including a thesis defense).  At a minimum, the Special Committee of a Master’s degree candidate is composed of a chairperson and a faculty member representing a minor subject.  The student may invite a third faculty member to be on the committee if he or she chooses.  To take the Master’s degree path, the student must submit a Change of Program form to the Graduate School, requesting transfer from the PhD program to a Master’s program.  This form will then be sent to the DGS for approval.

B Exam: Thesis Defense

Defending a thesis successfully requires at a minimum that the student has obtained sufficient data to make a significant contribution to at least one research paper that has been submitted or published in a peer-reviewed journal.  If this expectation is not met, the Chair (thesis advisor), with help from the Special Committee, must determine that circumstances beyond the student’s control that prevented the student from meeting these expectations.

As with the A-exam, a Schedule of Exam form needs to be filled out and signed by your committee and the DGS and then submitted to GFAs for transmission to the Graduate School at least 7 days before the examination date. You are also required to provide the title and abstract for your dissertation and the list of your publications to the GFAs for the announcement of your exam.

Thesis Format

A section of the Graduate School website (http://gradschool.cornell.edu/thesis-dissertation) is dedicated to information about the dissertation process, including the Thesis and Dissertation Guide.  You are highly encouraged to follow the process it lays out in planning submission of your thesis and graduation.

The Graduate School Office of Academic & Student Affairs (http://gradschool.cornell.edu/academics/office-academic-and-student-affairs) also coordinates a number of workshops to assist you with thesis writing.

Your thesis may be organized either as a single work (traditional thesis) or as a series of relatively independent chapters (independent chapter thesis).  In the latter case, there may be a unified introduction and bibliography or separate introductions and bibliographies.  There may be a unified summary, or the two-page abstract (required of all theses) can serve as a summary statement for all chapters.  Some examples of thesis formats are shown below.

Appendices

The independent chapter option allows you to prepare your thesis as a series of papers in a format ready for publication, and chapters can be published before the thesis defense.  The work in your thesis must be primarily, if not entirely, your own.  If your published work includes co-author(s), you may cite the work of your co-author(s) in your thesis with appropriate acknowledgment, but you should not include the data of your co-author(s) in your thesis.  An exception could be if data from a co-author are needed for clarity.  In that case, the legend to the figure should explain this.  You should acknowledge in the publication that the research is part of a thesis, and the Graduate School requires written permission from the publisher to include it in your thesis.

Full collections of dissertations are maintained in Mann Library.  There are also a collection of theses of graduates in the Fields of Genetics, Genomics and Development and Biochemistry, Molecular and Cell Biology in the Keller Reading Room, Biotechnology Building, Room G09.  You can view these by asking someone in the MBG Department Office (107 Biotech) to let you into this room.  Please ask to be let into that room.  NOTE:  Materials are NEVER to be removed from this room.

Final Thesis Seminar

The final thesis seminar usually is given immediately before or on the same day as the thesis defense, i.e. the “B” exam.  However, in very rare cases, students may want to present the thesis seminar up to six months before the B exam, for example, to allow input from the special committee about final experiments.

Thesis Defense | B Exam

To schedule the oral defense of the Ph.D. thesis (B exam):  at least seven days before the exam you must distribute your thesis to the Special Committee; the thesis must be complete in all respects and editorially acceptable for final approval.  After filling out the Schedule of B exam form and obtaining the signatures of all members of your Special Committee and the DGS, bring it to the GFAs for their signature and transmission to the Graduate School. You should also provide the GFAs with the title and abstract for the thesis seminar, and a publication list including all manuscripts you have published, submitted or are in preparation.
NOTE: Once the final thesis is submitted and approved, your status as a registered student ends, which means that your stipend will end as well.  Plan accordingly. For International students, your F1 visa status will also expire.  Talk to ISSO about OPT and other visa status options.
