Approved Mathematics Courses

Any graduate-level course within the Department of Mathematics and Statistics is approved.

Research Rotations

During their first year, students are required to register for and complete at least one research rotation (3 units) with program faculty mentors. The research rotations allow students to sample different research projects and laboratory working environments before selecting the group in which they will carry out their PhD dissertation research.

A rotation will be chosen in consultation with program faculty and must be mutually agreeable to both the student and the mentor. At the completion of each rotation, the student must submit to the mentor and director a written report approved by the mentor.

Qualifying Exam

A written qualifying exam will be administered during the spring of the student's second year of graduate school. The examining committee, which will develop and grade the exam, will consist of three members of the Imaging Science PhD Program Committee. The director of the graduate program will approve the committee, the members of which will be suggested by the thesis advisor.

Students will choose three out of the following four exam topics:

  • Mathematics of Imaging Science
  • Imaging Physics & Image Formation Methods
  • Image Analysis & Data-Driven Imaging
  • Theoretical Image Science

Finding a Thesis Research Mentor

Because the PhD is a research degree, the student is expected to become integrated within a research group. By the end of the first year of study, students should have found a thesis advisor who will oversee their PhD research and assume financial responsibility for their stipend, tuition, health insurance and student fees. The thesis advisor must be a faculty member on the Imaging Science PhD Program Committee with the title of professor, associate professor or assistant professor. Failure to find a research advisor by May 1 will result in the student being placed on probation that can last until August 31. During that time, the student must continue to seek a research advisor. Failure to find a research advisor by August 31 will lead to dismissal from the PhD program and termination of funding.

Research Presentation/Thesis Proposal

Before the end of their third year, the student will give an oral presentation of their proposed PhD project — with the necessary background to support it — to the Thesis Committee. This committee will consist of six members; four members must be members of the Imaging Science PhD Program Committee. At least one committee member must be chosen from outside of the Imaging Science PhD Program Committee, and this individual must be a tenured or tenure-track faculty member at Washington University. The committee will be chaired by the PhD mentor. At least two weeks prior to the presentation, the student will present to the Thesis Examination Committee a written document outlining the research background, proposed procedures, preliminary results and plans for completion. The required document will typically be between 15 and 30 pages in length, and it must contain a comprehensive bibliography.

The student will be placed on probation if they fail to pass their thesis proposal by the sixth semester. The student will be given a second opportunity to pass the exam during their seventh semester. If the student passes the second exam and meets the other program requirements (e.g., grades), they may continue the program without prejudice. If the student fails the exam a second time, they will be terminated from the PhD program.


The student will prepare a written dissertation for examination by the Thesis Examination Committee. The student will defend the dissertation before this committee. Should a member of this committee be unable to participate, the director of the graduate program, in consultation with the PhD mentor, will choose a replacement. If the committee members feel that the dissertation has deficiencies, they may recommend that the candidate address them and send the revised dissertation to the committee members for approval. The committee may also recommend that the candidate present another oral defense of the modified work. The Committee will inform the director of the graduate program, and they will warn the student in writing that the student must submit a revised dissertation and pass the oral defense (if recommended) in order to complete the PhD program. If, after revision and reexamination, the Committee still finds deficiencies and cannot reach unanimous agreement to approve the dissertation, the policy from the Office of the Provost on Dissenting Votes will apply.   

Teaching Requirements

Students in the PhD program will receive formal pedagogical training by attending a minimum of two teaching workshops offered by the Center for Teaching and Learning. They will be expected to fulfill the teaching requirements of their designated administrative home departments. The teaching requirements must be completed before the students submit their doctoral dissertations to the McKelvey Registrar.
