Senior Thesis

A thesis is a more ambitious undertaking than a project. A project that meets the honors modeling requirement (either through Applied Mathematics 115, 91r, or through other means) can be extended to a thesis with about one semester of work.  See the above section on English Honors for details on how to satisfy the honors modeling requirement.  Obviously the more time that is spent on the thesis the more substantial the outcome, but students are encouraged to write a thesis in whatever time they have. It is an invaluable academic experience.

The thesis should make substantive use of mathematical, statistical or computational modeling, though the level of sophistication will vary as appropriate to the particular problem context. It is expected that conscientious attention will be paid to the explanatory power of mathematical modeling of the phenomena under study, going beyond data analysis to elucidate questions of mechanism and causation rather than mere correlation. Models should be designed to yield both understanding and testable predictions. A thesis with a suitable modeling component will automatically satisfy the English honors modeling requirement; however a thesis won't satisfy modeling Breadth section (v) unless the student also takes Applied Mathematics 91r.

To write a thesis, student's typically enroll in Applied Mathematics 91r or 99r or both during their senior year.  Applied Mathematics 99r is graded on a satisfactory/unsatisfactory basis.  Usually concentrators will have completed their programs of study before beginning a thesis; but in those situations where this is necessary, students may take Applied Mathematics 91r for letter-graded credit, for inclusion in Breadth section (v) of the plan of study, with the thesis serving as the substantial paper on which the letter grade is based.

Students specializing in mathematical economics may substitute one of the Economics 985 thesis seminars for Applied Mathematics 99r. These seminars are full courses for letter-graded credit which involve additional activities beyond preparation of a thesis. They are open to Applied Mathematics concentrators with suitable background and interests.

Students wishing to enroll in Applied Mathematics 99r or 91r should bring the application available from the Office of Academic Programs (Pierce 110), signed by the thesis supervisor, to the Directors, Associate Director, or Assistant Director of Undergraduate Studies, who will sign the student’s study card.

Thesis Timeline

Early September:

Students often find a thesis supervisor at this time, and work with their supervisor to identify a thesis problem.  Students may enroll in Econ 985 (strongly recommended when relevant), AM 91r, or AM 99r to block out space in their schedule for the thesis.

Early December:

All fourth year concentrators are contacted by the Office of Academic Programs.  Those planning to submit a senior thesis are requested to supply certain information.  This is the first formal interaction with the concentration about the thesis.


A tentative thesis title approved by the thesis supervisor is required by the concentration.

Early February:

The student should provide the name and contact information for a recommended second reader, together with assurance that this individual has agreed to serve. Thesis readers are expected to be teaching faculty members of the Faculty of Arts and Sciences or SEAS.  Exceptions to this requirement must be first approved by the Directors, Associate Director, or Assistant Director of Undergraduate Studies.  For students writing theses in mathematical economics, the second reader will be chosen by the Economics Department.

March 27:

Thesis due at 4 pm. Electronic copies in PDF format should be delivered by the student to the two readers and to (which will forward to the Directors of Undergraduate Studies, Associate and Assistant Director of Undergraduate Studies) on or before that date. An electronic copy should also be submitted via the SEAS online submission tool on or before that date. SEAS will keep this electronic copy as a non-circulating backup and will use it to print a physical copy of the thesis to be deposited in the Harvard University Archives. During this online submission process, the student will also have the option to make the electronic copy publicly available via DASH, Harvard’s open-access repository for scholarly work.

Contemporaneously, the two readers will receive a rating sheet to be returned to the Office of Academic Programs before the beginning of the Reading Period, together with their copy of the thesis and any remarks to be transmitted to the student.

Late May:

The student may pick up the readers' comments from the Office of Academic Programs in late May, after the degree meeting to decide honors recommendations.

Thesis Readers

The thesis is evaluated by two readers, whose roles are further delineated below.  The first reader is the thesis adviser.  The second and reader is recommended by the student and adviser, who should secure the agreement of the individual concerned to serve in this capacity.  The reader must be approved by the Directors, Associate Director, or Assistant Director of Undergraduate Studies.  The second reader is normally are teaching members of the Faculty of Arts and Sciences, but other faculty members or comparable professionals will usually be approved, after being apprised of the responsibilities they are assuming.   For theses in mathematical economics, the choice of the second reader is made in cooperation with the Economics department.  The student and thesis adviser will be notified of the designated second reader by mid-March.

The roles of the thesis adviser and of the outside reader are somewhat different.  Ideally, the adviser is a collaborator and the outside reader is an informed critics.  It is customary for the adviser's report to comment not only on the document itself but also on the background and context of the entire effort, elucidating the overall accomplishments of the student.  The supervisor may choose to comment on a draft of the thesis before the final document is submitted, time permitting.  The outside reader is being asked to evaluate the thesis actually produced, as a prospective scientific contribution — both as to content and presentation.  The reader may choose to discuss their evaluation with the student, after the fact, should that prove to be mutually convenient.


The thesis should contain an informative abstract separate from the body of the thesis.  At the degree meeting, the Committee on Undergraduate Studies in Applied Mathematics will review the thesis, the reports from the two readers and the student’s academic record. The readers (and student) are told to assume that the Committee consists of technical professionals who are not necessarily conversant with the subject matter of the thesis so their reports should reflect this audience.

The length of the thesis should be as long as it needs to be to make the arguments made, but no longer!
