Welcome to the Applied Mathematics Group in the Department of Mathematics at Iowa State University. This page gives a detailed overview of the following programs offered in Applied Mathematics. There are four main categories of graduate degrees that are offered in Applied Mathematics:
- Ph.D. in Applied Mathematics (for students in the Department of Mathematics)
- M.S. in Applied Mathematics (for students in the Department of Mathematics)
- Co-major Ph.D. in Mathematics + Outside Area (for all graduate students)
- Graduate minor in Applied Mathematics (for gradute students from outside departments)
See below for more information.
Ph.D. in Applied Mathematics
A Ph.D. student is required to a attain a minimum of 72 acceptable credits, with at least 36 of these earned in residence. At least 42 credits must be in formal courses (not research); 18 of the 42 must be in the core courses. In addition, at least 36 must at the 500-600 level, excluding Math 590, 591, 592, 599 and 699. At least 36 of these must be in 500-600 level Mathematics courses, excluding Math 590, 591, 592, 599 and 699. There is also a 1 credit seminar requirement which is satisfied by taking both Math 591 and Math 592.
Included in the 42 credits of formal courses is a 6 credit cognate study requirement. A cognate course is defined to be a course which is (i) acceptable for graduate credit, (ii) taught in another department (a course cross-listed with Mathematics can count toward the cognate requirement if taught by a faculty member whose primary appointment is not in the Mathematics department, or if approved by the Graduate Committee), and (iii) relevant to the major. The course work for the cognate study requirement must be approved by the student’s Program of Study (POS) committee. Students are encouraged to consider a minor in another department to meet the cognate study requirement. The student is also required to take at least 3 credits of Math 699 (Research in Mathematics).
In addition to the course work, the Ph.D. student must pass four written qualifying examinations, pass an oral preliminary examination, prepare a dissertation, and pass an oral final examination which is usually limited to the defense of the dissertation. These requirements are described in subsequent sections. A grade of B or better must be earned in each core course, and a grade of C or better in all other courses of the Program of Study (POS). The student must maintain a cumulative grade point average of at least 3.33 in graduate level mathematics courses and of at least 3.0 in all course work, exclusive of research credit.
Core course requirements
The core course requirements for the Ph.D. in Applied Mathematics are:
- At least 6 core courses.
- At least 3 core courses must be in Applied Mathematics or Numerical Analysis.
- The core courses must include Math 519 and Math 561.

A grade of B or better must be earned in each core course used to satisfy the requirements in this section. A deffciency may be made up any one of the following methods:
- Retaking the course for credit and earning a B or better.
- Retaking the final examination of the course and earning a B or better (permission of the instructor giving the final is required).
- A pass on the associated qualifying examination, if such examination exists. Students are strongly encouraged to consult their advisor prior to deciding which core courses to take, since certain core course combinations may not be suitable for certain areas of research.
A Ph.D. student in the Mathematics Program must pass four written Qualifying Examinations, including:
- at least two in Applied Mathematics and/or Numerical Analysis, and
- at least two in one area.
The 10 qualifying examinations are (listed as examination name, associated course #, area):
- Applied Mathematics I, Math 519, Applied Mathematics
- Applied Mathematics II, Math 520, Applied Mathematics
- Numerical Analysis, Math 561, Numerical Analysis
- Numerical Linear Algebra, Math 562, Numerical Analysis
- Abstract Algebra, Math 504, Algebra
- Linear Algebra, Math 510, Algebra
- Real Analysis, Math 515, Analysis
- Complex Analysis, Math 511, Analysis
- Graph Theory, Math 607, Discrete Mathematics
- Enumerative Combinatorics, Math 606, Discrete Mathematics
A student granted full admission to the Ph.D. program is expected to pass four qualifying examinations (subject to the rules above) within the first two calendar years in the program.
Oral preliminary exam
The oral preliminary examination of a Ph.D. student tests a student’s knowledge of the major, minor and supporting fields of their research area. The examination is taken after a student has passed four written qualifying examinations, satisfied the graduate English requirement (if required), formed a Program of Study (POS) committee, and has an approved Program of Study (POS) form.
Final oral examination
The final examination of a Ph.D. candidate is oral, and is usually limited to a defense of the dissertation.
Graduate English requirements
Graduate students whose native language is not English must meet the Graduate College English Requirement.
Each Ph.D. student is required to have one year of supervised teaching. However, if approved by the student’s Program of Study (POS) committee, equivalent supervised experience in oral mathematics communication may be substituted for teaching. In that case the Program of Study (POS) committee must specify in writing what the equivalent experience will be.
M.S. in Applied Mathematics
An M.S. student is required to a attain a minimum of 30 acceptable credits, with at least 22 of these earned in residence. The total of 30 credits must include 21 hours of 500-600 level mathematics courses excluding Math 590, 591, 592, 599 and 699, and these 21 hours must include at least 12 hours of core courses subject to the conditions (see below). There is also a 1 credit seminar requirement which is satisfied by taking both Math 591 and Math 592.
Each student must elect one of the following options:
- Thesis option: the thesis program required 6 credits of Math 699, which may be included in the 30 credits. The Masters thesis must include original mathematical work.
- Non-thesis option: non-thesis program requires a creative component that entails reading, synthesizing, and presenting mathematical content from approved journal articles. Three credits of Math 599 may be included in the 30 credits for the creative component.
Core course requirements
The core course requirements for the M.S. in Mathematics are:
- At least 4 core courses.
- At least 2 core courses in Applied Mathematics (Math 519, Math 520, Math 557) or at least 2 core courses in Numerical Analysis (Math 561, Math 562, Math 517).
Note about cognate study
Although cognate study (as described in above) is not required at the M.S. level, it is strongly recommended. When cognate study is in the form of a minor, it typically consists of 6-9 credits in a department other than Mathematics. These credits must be acceptable to the representative of the minor department on the student’s POS (Program of Study) committee.
Final oral examination
The final examination of an M.S. candidate is oral and comprehensive. It normally consists of a defense of the thesis or creative component and an examination of the candidate’s knowledge of the topics covered in the program of study.
Co-Major in Applied Mathematics and Outside Area (Interdisciplinary Ph.D.)
Well-qualified students are encouraged to consider a Ph.D. program having a co-major in Applied Mathematics and some other appropriate program. Such programs are to be initiated by a written proposal from the student to the Mathematics Department Graduate Committee. The proposal must contain an outline of how all requirements are to be met. Authorization by the Graduate Committee to embark on a co-major program will be based on this proposal, and on the academic history of the student. The Program of Study (POS) committee is to be directed by co-chairmen, one from each of the co-major departments. The dissertation must have significant content in both fields. Co-major programs are subject to the following minimum standards.
Co-major Ph.D. students are required to earn at least 24 credits in 500-600 level mathematics courses other than Math 590, 591, 592, 599 and 699. They are required to take a total of four courses from the applied mathematics core including at least one one-year sequence (Math 561-562 or Math 519-520). They are also required to pass two of the qualifying examinations.
- Co-major Ph.D. students are required to have two years of professional experience including at least one year of supervised teaching. The other year may be supervised research as a research assistant or associate.
Graduate Minor in Applied Mathematics (for graduate students from other departments)
Ph.D. students who declare a minor in Applied Mathematics are required to have at least 12 credits in Mathematics courses which are acceptable for non-major graduate credit, excluding Math 590, 591, 592, 599 and 699, and of which at least 6 must be in 500-600 level Mathematics courses.
M.S. students who declare a minor in Applied Mathematics are required to have at least 6 credits in Mathematics courses that are acceptable for non-major graduate credit, excluding Math 590, 591, 592, 599 and 699, at the 400-level or above.
