CAMB students must carry out their thesis research under the mentorship of a faculty member of the Cell and Molecular Biology Graduate Group. The Thesis Mentor is the most important individual the student will interact with in the course of their graduate training. For this reason students should carefully evaluate their three rotation experiences in choosing the Mentor. If necessary the student can do additional rotations. At the end of all the rotations the Mentor is chosen and thesis research should commence as soon as possible. The Thesis Mentor is responsible for supporting PhD students beginning June 1st of the PhD student's second year or the MD/PhD student’s fourth year. Below are documents from BGS with more detailed financial information.
Within six months of passing the preliminary exam, the student must form a Thesis Committee, and have their first committee meeting. Failure to formulate a Thesis Committee within this time frame will result in the student being placed on academic probation. The Thesis Committee must meet at least once a year for Ph.D. students and every six months for combined degree students to monitor student progress. It is the student’s responsibility to initiate the scheduling of these meetings.The Program Chair will monitor the frequency of thesis committee meetings.
The Thesis Committee will be comprised of four (or more) faculty (not including the Thesis Mentor), at least three of whom must be members of the CAMB Graduate Group. One of the four faculty is designated as committee chair, and he or she must be a CAMB member. The committee should be constituted to include breadth as well as expertise in the particular research area of thesis work. No more than one faculty member per lab can serve on a student's committee. The Thesis Mentor is a non-voting, ex-officio member of the thesis committee.
The Thesis Committee is the student's advocate and advises the student on scientific direction. The thesis committee, in consultation with the mentor and the student, decides whether a student may defend his/her thesis. It may intervene if there is a serious disagreement between the student and the mentor. If a serious disagreement arises between committee members, the committee Chair should inform the relevant Program Chair. The Program Chair must approve the composition of each thesis committee in their Program, and when necessary, at his/her discretion, may add additional members or reformulate a committee. If a dispute arises between a student and the thesis committee, and the student requests it, the decisions of a thesis committee will be reviewed by the CAMB Executive Committee.
The graduate student and his/her Program Chair shall jointly select the members of the Thesis Committee. The student should submit a list of potential committee members, indicating which faculty will serve as committee chair, to their Program Chair in writing. The Program Chair will respond in writing to approve the committee composition or make recommendations for other candidates. The Graduate Group Chair will adjudicate any disagreement on the composition of the Thesis Committee.
The Thesis Committee and the committee chair must be registered with the Graduate Group Office as soon as it is approved. Students must contact the Graduate Group Office before each thesis committee meeting is held. The student will provide the members of the thesis committee and the Graduate Group Office with a brief progress report including results obtained and experimental plans, no longer than 2-3 pages, 3 days prior to the meeting. The Graduate Group Office will then send thesis committee evaluation forms (appendix) to the committee chair. The committee chair will write an overall summary of the committee's decisions. The summary will be returned to the Graduate Group Office to be placed in the student's academic file, and a copy will be forwarded to the student.
BGS has mandated that all graduate groups ensure that students properly maintain laboratory notebooks and records. Students are requested to bring their most recent laboratory notebook to each thesis committee meeting. The thesis committee chair will appoint a committee member to review the notebook.
The purpose of this review is to ensure that students record their primary data in a manner that allows for appropriate analysis, reanalysis and documentation as necessary. The objective is NOT to monitor the precise content of the notebooks, but to ensure that these essential records of research activity are maintained in an acceptable format. While there will be variation in notebook format, the following requirements must be met:
If parts of these requirements are not applicable to a specific project (e.g., studies generating mostly large data sets or image stacks), the thesis committee will advise the PI and the student of the best manner to maintain experimental records. At a minimum, hard copy records must be kept that identify the unique file names and storage locations for all digital data sets.
Notebooks/records should be checked at each thesis committee meeting. If weaknesses are found in notebook/record organization, then the student and PI will receive guidance from the thesis committee on necessary improvements. It is the responsibility of the PI and the student to fully address issues identified by the thesis committee.
Students who have not completed all requirements for the Ph.D., including the deposit of the dissertation, within 5 years of passing the preliminary examination cease to be candidates for the Ph.D. unless they satisfy the following re-evaluation process: At a special meeting of the Thesis Committee plus three members of the CAMB Executive Committee, the student will make a 50 minute presentation of work completed to date, plans for future experiments and a detailed timeline for completion. This must be approved by the Thesis Committee and the CAMB Executive Committee. This approval constitutes the "recertification"
The Graduate Group requires a dissertation that represents a definitive contribution to scientific knowledge and that demonstrates the student’s ability to perform independent research. The dissertation should contain experimental information that answers a stated question and should display a logical progression of scientific thought. Graduates should have as their goal accomplishing work resulting in two or more lead-author research publications in peer-reviewed scientific journals. At a minimum, one lead-author peer-reviewed research publication should be in press prior to the granting of permission to write and defend the thesis. The thesis committee has the final authority to grant permission to write and defend the thesis. However, in cases where these standards are not met, the thesis committee must consult with the Program Chair prior to granting permission to write the thesis.
When permission to write is granted, the "Permission to Write" form (appendix) must be signed by the committee chair and thesis advisor and returned to the Graduate Group Office. The committee should also agree on a time line that includes an approximate date for the defense. This is necessary to ensure that a time convenient for all committee members can be arranged and that an appropriate room can be scheduled. A draft of the thesis must be presented to each committee member and the CAMB office no later than two weeks prior to the scheduled defense. Failure to do this may result in cancellation of the scheduled thesis defense. Prior to distributing the dissertation to the thesis committee, it must be approved by the thesis advisor. It is typical for members of the thesis committee to ask for alterations prior to the dissertation’s final submission; such alterations can be requested at the thesis defense.
The dissertation is the document that summarizes the student’s experimental work, formally stating the hypothesis (or hypotheses), the background for forming the hypothesis, and the complete, logical set of experiments and methods used to prove or disprove the hypothesis. It describes primarily data obtained independently by the student, including those generated from incomplete and/or rotation projects (if desired), but may also describe collaborative work. For the latter, it is critical that the student be the primary author and provides the appropriate acknowledgments to other contributors. In addition to being a document that summarizes the research accomplishments of the student, the dissertation is also an invaluable lab resource and should be written as such.
The basic outline of the dissertation comprises five sections:
a) A General Introduction, which is intended to review in depth the literature that places all of the work in context and to state the initial hypothesis or hypotheses;
b) Materials and Methods, which should be complete and sufficiently detailed so that others can repeat the experiments without undue literature searches;
c) Results, which typically consists of more than one chapter, with each chapter corresponding to a completed or submitted manuscript or to work in progress. The chapters can contain their own Introductions (these cannot replace the General Introduction described above), Materials and Methods and Discussion sections. The text of these chapters may be more detailed than a completed or submitted manuscript; for example, the Methods should be completely described so that others can repeat the experiments or use the same technology.
d) Conclusions/Future Directions, which defines the major conclusions and advances accomplished, and places these within the context of related areas of research and major unanswered questions in the field. This chapter should not just summarize the results obtained, but should be a broader synthesis of the importance and implications of the work accomplished, and the major directions for future work. This section is required even if chapters in the Results section have their own Discussions.
e) References. Depending on the overall organization of the dissertation, these can be included at the end of each chapter or at the end of the document.
Following this general outline, the dissertation’s overall organization is up to the student in consultation with the thesis advisor and chair of the thesis committee. The written document must conform to the dissertation rules of the University (see the Dissertation Manual issued by the Office of Graduate Studies).
The thesis presentation will take the form of a public lecture. The lecture should be scheduled well in advance so that a time convenient for the entire committee can be found and notices can be sent to the faculty and student membership. The Graduate Group Office needs to know the defense date, title of the thesis and place and time of the defense at least three weeks in advance. The Graduate Group Office will then send a public notice to the University community advertising the thesis defense. The Graduate Group Office is responsible for obtaining faculty sign-off of forms that are required after the thesis defense.
Every effort should be made to have the full four-member thesis committee present at the thesis defense. If a thesis committee member cannot be present at the defense, he/she may provide to the committee chair approval of and/or comments concerning the thesis prior to the defense. If that is not possible, the student is responsible for finding a substitute committee member, with the approval of their program chair. Following general questioning during the public phase of the presentation the thesis defense will commence. The defense is open only to the thesis committee and mentor. The decision on approval of the thesis will be made solely by a majority vote of the committee. The student should anticipate that the committee may require changes to the thesis that could include additional writing, editing and re-evaluation of data. Such changes must then be approved by the committee before the thesis is deposited. For this reason, it is imperative that thesis defenses be scheduled no later than two weeks before the deadline for depositing theses.
Before a student makes the appointment to deposit the thesis, the student must provide the Graduate Group Office with a copy of the abstract page, an original signed copy of the title page, and a mailing address where the postdoctoral training will be done. The Graduate Group Office will then provide the student with a signed 153 form, which must accompany the dissertation to the Graduate Division of Arts and Sciences (GAS).
The Graduate Division of Arts and Sciences sets three graduation dates each year in May, August, and December. A formal commencement ceremony is held in May. The Graduate Group Office will distribute a calendar for each degree period, giving the deadlines for signing up for graduation, and for defending and depositing the thesis. If a student is not able to graduate after they have signed up, they must re-apply for the next degree period. The graduate Group Office will guide students through the thesis submission and graduation scheduling.
A "Graduation Checklist" that includes all of these processes and procedures can be found in the Appendix.
