The program of studies for a Math Department PhD student is divided into two main parts: Pre- and Post-Candidacy. Before taking the Candidacy Exam, students need to fulfill numerous requirements which ensure solid preparation in core mathematical areas as well in their chosen specialization. These include passing the Qualifying Requirements as well as fulfilling the Breadth and Foreign Language requirements. The Candidacy Exam is usually taken sometime during the third year, marking the end of the preparatory period and the beginning of research leading ultimately to the PhD Dissertation. Time from admission to graduation usually averages around 6 years but may vary greatly depending on many factors such as initial preparation level, individual academic progress, complexity of chosen specializations, and strategic thesis and job decisions. The Mathematics Department Graduate Handbook has a more detailed explanation of departmental expectations. The OSU Graduate School has requirements as well, which can be found in the Graduate School Handbook.
All newly admitted graduate students are required to arrive 4 weeks prior to the beginning of the Autumn semester in order to participate in our Headstart Training teaching preparation program. This is prerequisite for holding a GTA appointment and includes half-day sessions. Further academic preparation activities are scheduled during this time as well. Exceptions can be made only for students who are offered university fellowships and typically involve a one-year deferment of the summertime training. You are paid a modified stipend during this time-frame.
There are four Qualifying Requirements corresponding to the content of the four courses Math 6111, Math 6112, Math 6211, and Math 6212 in Abstract Algebra and in Real Analysis. Each requirement can be passed by either receiving a grade of A or A- in the respective course, or by receiving a passing grade on a respective (separate) qualifying examination. The Math 6111 and 6211 courses are offered every Autumn Semester and the Math 6112 and 6212 courses are offered every Spring Semester. The four examinations, one for each course, are offered each August (typically in the week before the start of classes) and are open to incoming students. Each exam is two hours long and covers roughly the material of the respective courses.
All four requirements need to be fulfilled by the end of the third semester of study. Thus a student has four attempts to fulfill, for example, the 6111-requirement (twice by taking the course, and twice by exam) and three attempts to fulfill the 6112-requirement (once by taking the course, and twice by exam). The 6211 and 6212 requirements are analogous.
Interested students may substitute one of these four requirements by an approved 6000-level year-long course sequence with A or A- grades. For example, the 6112 requirement can be substituted by taking the Math 6411-6451 Differential Equations sequence with A or A- grades in each course.
Passing the Qualifying Requirements also entails an increase in stipend amount assuming otherwise satisfactory academic progress (see Financial Support). The outcome of initial exams and course work will also inform future advising.

Advisor and Breadth Requirements
Upon attaining Regular PhD status, students are matched with faculty members who guide them to potential dissertation research ideas. The primary task of this Dissertation Advisor is to facilitate their advisee’s development as a mathematician.
The course work required for admission to Candidacy is referred to as our Breadth Requirements. The purpose of these requirements is to ensure that graduates master not only their eventual field of specialization but also develop the breadth, versatility, and maturity expected from mathematicians working in academic professions that traditionally require a PhD. They require the following:
- Course Sequences: Complete a year-long sequence from each of three different mathematical areas (see below)
- All courses must be passed with a grade of B+ or higher
- Course sequences used for the qualifying requirement (such as, for example, 6111-2) may also be used for the breadth requirement. However, a passed qualifying exam does not count towards a breadth requirement.
Nearly all PhD students complete their Breadth Requirements within their first two years from admission. General expectation is that students fulfill two breadth sequences within one year from passing their Quals and the third one in the following year. Timely completion of breadth requirements may influence stipend level and summer support.
All Breadth Requirements must be completed by the time of the Candidacy Exam.

Specialization & Advisor
An important candidacy requirement is the choice of a dissertation specialization and a Dissertation Advisor. The diligent, timely, and careful pursuit of a future research direction is likely the most important responsibility of a prospective PhD candidate. The student should be fully invested in the choice of specialization which will impact his/her future academic trajectory more than anything else. There are currently 65 regular mathematics faculty on the Columbus campus and over 20 more faculty on the branch campuses who can supervise doctoral theses. Consult our current Graduate Faculty List for names, contacts and specializations. Under special circumstances students can also be advised by faculty outside of the department. The advisor pool in our department is thus as large as that of any department in the country.
There are numerous opportunities for students to get to know potential advisors. This includes having them as teachers in introductory classes, visiting the Invitation to Mathematics lecture series, regular research seminars and colloquia (see Events), or self-development through academic advisors, peers, and publicly available research information. After narrowing down possible specializations students typically sample faculty and topics by taking numerous reading courses (MATH 6193) on special topics with a few prospective advisors. These provide introductions to future research areas that are too specialized to be covered in regular courses. The one-on-one teaching of a reading course may also serve as a preview of the advisor / advisee interaction in future thesis work.
The choice of thesis advisor usually evolves out of this process. After student and faculty agree on the thesis advising, the student reports the change from the Preliminary Academic Advisor to the chosen Dissertation Advisor to the Math Graduate Office using the form located outside the Grad Office. Typically students should choose a Dissertation Advisor about two years after passing their qualifiers.
Master's of Science (MS) Degree
Normally the department does not admit students whose intended degree is a generic Master's outside of the MMS specializations program. However, students admitted for the PhD can obtain a general MS degree in Mathematics during their academic progression towards the PhD degree.
There are three ways for a PhD student to earn an MS degree (listed below). Details can be found in our Mathematics Graduate Handbook.
- Candidacy: Submit an additional form after passing the candidacy examination to receive the MS Degree
- Thesis Option: After completing 30 credit hours of approved work, a student may select the option of writing a thesis which has to be defended and approved by a two-faculty member exam committee, one of whom has to be the student's Master's Faculty (Thesis) Advisor.* Students utilizing this option should be signed up for MATH 6999 with the supervising Master's Faculty (Thesis) Advisor during the semester they write and defend their thesis.
- Non-thesis Option: This option requires 30 credit hours of approved course work as well as a Master's Pass on the Analysis and Algebra qualifying exams. In addition, it requires a four-hour written examination on any subject given by a two-faculty member exam committee, one of whom has to be the student's Master's Faculty (Non-Thesis) Advisor.*
The Master's Thesis needs to follow university formatting guidelines, be approved by the exam committee, and be submitted to the OSU Graduate School and OhioLink. For further details see Section VI of the Graduate School Handbook.
* The Master's Faculty (Thesis and/ or Non-Thesis) Advisor needs to be a Math Department faculty member of category M level or higher. They are selected separately from your Dissertation Advisor. When the student has established with a faculty member that they will advise the students Master's Thesis, the student reports the chosen Master's Faculty (Thesis and/ or Non-Thesis) Advisor to the Math Graduate Office.
For a graduate student to become an official PhD Candidate he/she has to pass the Candidacy Exam. The Candidacy Exam evaluates the validity and scope of the dissertation proposal, and serves as a forum for critique and guidance towards the successful completion of dissertation research. This exam is regulated by the university's Graduate School and permission from the department to take the exam is subject to the following requirements (for more detailed information on Candidacy see https://gradsch.osu.edu/handbook/all#7-0). These concern the composition of the committee, the written, and the oral portion of the examination:
Committee: The committee consists of four regular faculty with graduate P-status, including the advisor of the candidate who serves as the chair. Other committee members can be from other Ohio State departments but have to have graduate P-status in their programs. Additional members, beyond these four, can be added by petition and according to Graduate School rules.
Written Portion: The written portion consists of a 10-15 page dissertation proposal in which goals, scope, methods, and background of the planned research is outlined. The document has to contain mathematically rigorous statements, needs to be type-set along the usual publishing standards in the field (e.g., LaTeX), and should contain a substantial bibliography that includes all pertinent publications the intended research will be based on. The proposal of the written portion should be submitted to the committee at least three days before the presentation and oral portion.
Presentation: The candidate is required to describe his/her proposal in a short presentation of approximately 20 minutes to the committee immediately before the start of the oral portion of the examination. The details of the format are determined by the advisor, including whether the presentation should be public and questioning during the presentation.
Oral Portion: Following the presentation there is a two-hour oral examination by the committee. This time has to be completely dedicated to the questioning by the committee and is not allowed to contain further presentations. The questions can focus on the proposal itself and the validity and relevance of the research questions, but can also include skill and knowledge examination of the needed mathematical background, as well as test familiarity with prior research.
Timeline: The entire examination, including the written and oral portions, must be completed within 30 days. An application for candidacy must be submitted via gradforms.osu.edu at least two weeks before the oral examination. The candidacy examination can be taken at any time during business hours when the university is open -- including summer terms and breaks.
Other Requirements: All pre-candidacy requirements of the Mathematics Department as well as all credit and residency requirements by the Graduate School have to be fulfilled by the end of the term prior to taking the exam. Candidates also need to be enrolled for at least 3 hours at the graduate level (excluding foreign language classes) during the term of the exam.
Following the exam, the Candidacy Examination Report, provided by the Graduate School to the Candidacy Exam Committee Chair (the student's advisor), has to be submitted to the Graduate School within one working day after the oral portion.
Post-Candidacy & Dissertation Research
After the Candidacy Exam, PhD students spend most of their time on research related to their dissertation under the close supervision of their Dissertation Advisor.
There are some requirements during this time which PhD Candidates must abide by:
- Three-Hour Enrollment: Post-Candidacy students are expected to enroll for exactly 3 credit hours of MATH 8999 with their Dissertation Advisor every semester. Additional credit hours for enrollment are not included in the Graduate Associateship tuition waiver. A student may request to have tuition covered by the department for academically essential non-MATH courses by an application to the Graduate Studies Committee. In all other cases, tuition has to be paid for by the student or an external resource. Fellowship recipients will have different guidelines on this matter. NOTES: http://www.gradsch.ohio-state.edu/7.8-candidacy.html
- Continuous Enrollment: Students admitted 2008 or later who passed their candidacy examination are required to be enrolled during every semester. There are only exceptions for Summer and formal Leaves of Absence. For detailed rules on leaves see Section VII.8 of the Graduate Handbook and http://www.gradsch.ohio-state.edu/appendix-e.html NOTES: http://www.gradsch.ohio-state.edu/3.1-course-load.html
Final Defense & Graduation
How long one takes to graduate may vary greatly depending upon initial preparation, their chosen specialization, difficulty and scope of the research problem, talent and diligence of the candidate, results required to be competitive in the chosen area and job market, and other factors. Requirements to be eligible for Graduation include:
- Time Limits: The university allows a maximum of five years from passing the candidacy examination until submission of the final copy of the dissertation. The Math Department however, has the expectation that you can accomplish this in three years or less. Continuation in the program is contingent on timely and satisfactory progress towards completing a dissertation as determined by the Graduate Studies Committee
- Credit Hours: Students are required to have accumulated 80 graduate credit hours of mathematics courses by the time of graduation. It is possible to substitute some of these by graduate credits with courses outside of the mathematics department if approved by the advisor and the Graduate Studies Committee. In addition, university rules require that 50 of these credit hours have to be beyond the Master's degree. http://www.gradsch.ohio-state.edu/7.2-credit-hours-and-residency-requirements-doctoral-degree.html
Once the Dissertation Advisor deems the Dissertation Doctoral Draft complete the candidate needs to assemble a Final Oral Exam Committee. The committee consists of the Dissertation Advisor and two additional regular category P level faculty members who will review the draft. The doctoral candidate must submit the Doctoral Draft Approval/ Notification of Final Oral Examination form to the Graduate School no later than two weeks prior to the proposed final oral examination date. The approval of the draft is followed by the two-hour Final Oral Examination (dissertation defense) conducted before the dissertation committee members listed plus a non-Math representative of the Graduate School. See the PhD Dissertations link on the Department website for samples of past approved Dissertations.
The department supports the search for academic jobs in several ways. Before graduation, the department provides travel support for deserving students, helps with letters, and circulates job opportunities. After graduation, many former students with sufficient teaching credentials can find employment as lecturers at the department for about a year while they are looking for jobs.
Program Time Expectations
- The qualifying requirement needs to be fulfilled by the beginning of the second year. The graduate studies committee may decide on conditional continuation at either regular or probationary level in close cases.
- International students need to be classroom certified by ESL/SEP by the beginning of their second year.
- Students are expected to pass the candidacy examination before the Autumn Semester of their fourth year.
- Students are expected to graduate by the end of their sixth year.
