Research and Study

The Ph.D. in industrial engineering program is intended for students who wish to prepare themselves for a career creating and cultivating new knowledge. In addition to a broad selection of technical research courses, the program emphasizes original research under the close supervision of a faculty member. Students develop an individualized research project that typically includes the design and analysis of experimental or theoretical work or the invention of new processes, techniques, or devices, which ultimately leads to original publications in the academic literature. The training is appropriate for people seeking a career in academia or in research and development in industry.

The coursework requires some diversity of technical skills in three major areas which include systems, human factors, and analytics. The systems area emphasizes the design, construction, and analysis of complex systems with interdependent parts that include people and machines. The human factors area emphasizes the interaction of people with systems, and includes the study and analysis of people's cognitive and physical limitations. The analytics area emphasizes the application of mathematical formula, including statistical approaches, as well as algorithmic and computational approaches to deriving knowledge from data. Each area is supported by several faculty members, and many faculty members support multiple areas; see Facilities in the Department of Industrial and Systems Engineering section of the Catalog to learn more about each research lab and its activities.

The Doctor of Philosophy program in industrial engineering requires a minimum of 72 s.h. of graduate credit. Students must maintain a cumulative g.p.a. of at least 3.50 to earn the degree. At least 36 s.h. must be taken in Department of Industrial and Systems Engineering courses (prefix ISE), including at least 24 s.h. in graduate-level courses numbered ISE:5000 and above. Students must enroll in ENGR:7270 Engineering Ethics once and in ISE:5000 Graduate Seminar: Industrial Engineering every semester. Credit in those two courses may be applied toward the 72 s.h. of required coursework.

Students must successfully complete coursework in each of three focus areas: see "Breath Requirement" below. The academic advisor and/or examining committee may decide a student must complete other requirements such as additional coursework or the acquisition of specific skills. The actual amount of coursework required is determined with the advice and consent of the academic advisor. Students who earned an M.S. at the University of Iowa may have satisfied this requirement. There is no world language requirement in the program.

Students are typically expected to have completed three academic years of residence at the UI, or two years if they already hold a recognized M.S. degree. For students who earned their M.S. degree at the UI, no more than 36 s.h. from the M.S. degree may be counted toward the Ph.D. degree. For students who earned their M.S. from another institution, a maximum of 30 s.h. may be transferred toward the doctoral program. The director of graduate studies reviews the transcripts of new students to determine which requirements have been met from previous coursework.

Excellence in research is the principal requirement for the degree. It is expected that the Ph.D. dissertation research project represents an original and significant contribution to the body of knowledge in the field. At least one accepted research article in a peer-reviewed journal as first author with the research advisor as a co-author, in addition to presentation of the research in a departmental seminar, are requirements. Submission of three, first-authored papers and at least one research presentation at a national conference is typical. In addition, students must fulfill the qualifying requirement, pass the comprehensive examination, submit the Final Examination: Advanced Degree form, complete a Report of Thesis Approval, and submit a copy of their thesis to the Graduate College by following the published guidelines and deadlines.

Breadth Requirement

Students must successfully complete at least 6 s.h. in approved courses numbered 5000 or above offered by the Department of Industrial and Systems Engineering in each of the three focus areas—analytics, human factors, and systems. Students with relevant academic background in these areas may be excused from the breadth requirement with approval of the director of graduate studies. Approved courses are listed below.

Qualifying Exam

Students interested in pursuing a Ph.D. are initially admitted as M.S. nonthesis students until they have completed the qualifying examination. This is typically achieved within their first three semesters if beginning the program without an M.S. degree, or within the first two semesters if beginning the program with an M.S. degree. Once the exam is passed, students are formally admitted to the Ph.D. program. The purpose of this qualifier is to determine a student’s proficiency in research and scholarship. 

Comprehensive Examination

The general rules for the administration of the Ph.D. comprehensive examination are contained in the policies and procedures of the Graduate College. The tradition in the department is for the comprehensive examination to consist of a written and oral component. Students write and submit a comprehensive examination document, usually called the dissertation research proposal, to each member of the examination committee two weeks before the examination date. During the examination, students make a roughly 30-minute presentation on the content of the research proposal. Committee members may ask questions regarding the proposal before, during, or after the oral presentation. Having satisfactorily completed the comprehensive examination, students are accepted as a candidate for the Ph.D. degree.

Final Examination (Dissertation Defense)

Each student must defend the completed dissertation in the final examination, which is conducted by the examining committee.

En Passant Option

Students admitted to the Ph.D. program may elect to earn their M.S. degree through the en passant option, with the permission of their Ph.D. committee. This option allows students to write an English-language manuscript as the first author and submit it to a peer-reviewed research journal in lieu of writing the M.S. thesis. With this option, students, in conjunction with their academic advisor, author a paper that serves as the foundation for the Ph.D. research. The decision to select this option must be made before the qualifying examination. The committee may determine, based on the published or submitted scholarship to peer-reviewed journals, that the presentation of a separate research thesis is not necessary. In this case, up to 9 s.h. in ISE:5999 Research: Industrial Engineering M.S. Thesis may be counted towards the nonthesis option. Students choosing the en passant option generally receive an M.S. degree without the thesis designation. 

For more detailed information about program requirements, see the Graduate Student Handbook or Graduate Program on the Department of Industrial and Systems Engineering website.

Applicants must meet the admission requirements of the Graduate College; for detailed information about Graduate College policies, see the Manual of Rules and Regulations on the Graduate College website.

Admission to the graduate program is competitive and based on an applicant's previous coursework, research, and industrial experience. The general admission standards are intended to maintain the quality of the graduate program and to ensure sufficient preparation required for timely degree completion. Specific admission standards may be waived by the Graduate Admissions Committee when other evidence of competence is compelling. These standards are minimum standards, and meeting these standards does not ensure admission to the program; admitted students typically exceed these standards. 

Applicants are expected to have a minimum cumulative g.p.a. of at least 3.00 on a 4.00 scale, and have earned a B.S.E. in industrial engineering degree or in a related science or engineering discipline. Applicants are required to submit the results of the Graduate Record Examination (GRE) General Test. The GRE Advanced Examination in Engineering is not required for admission to the program; however, these scores should be forwarded to the department if that examination is taken. The minimum GRE General Test requirement is a combined quantitative reasoning and analytic writing score of 300. There is no specified minimum requirement for the verbal reasoning portion of the test. 

International applicants whose first language is not English are required to submit the results of their Test of English as a Foreign Language (TOEFL), International English Language Testing System (IELTS), or Duolingo English Test (DET). Applicants who have completed a post-secondary degree at an English-speaking institution may request a waiver of this requirement. A minimum TOEFL score of 100, a minimum IELTS score of 7, or a minimum DET score of 105 is required for admission. 

Applicants must arrange to have three letters of recommendation sent to the department online through the Office of Admissions website. The letters should be completed by persons who are well acquainted with the applicant and the ability of the applicant to undertake graduate work in industrial or systems engineering. 

While the department considers applications at any time, first consideration is given to students who have their application materials, including their application, transcripts, GRE scores, TOEFL scores, and the required letters of recommendation, completed by the admission priority deadline as found on the Graduate Admissions website. The director of graduate admissions is responsible for overseeing the graduate recruiting activities and the admissions procedures in the department. The director serves as the point of initial contact between prospective graduate students and the department, and maintains a record of each qualified applicant in the departmental office. The director, in consultation with the Graduate Admissions Committee and the department chair, screens applicants and ultimately determines which applicants are extended offers of admission.

Applicants with Degrees not in Industrial or Systems Engineering

The department encourages students with degrees in other scientific disciplines, such as in computer science, mathematics, physics, or other engineering disciplines, to apply for admission. Some students may have already completed M.S. degrees; however, these students are expected to attain a proficiency in specified core areas of industrial and systems engineering equivalent to entering graduate students who hold a B.S.E. degree in industrial engineering. The background of each student admitted to the program with a degree other than in industrial or systems engineering is reviewed by the faculty members. These proficiencies are intended to ensure that each admitted graduate student is able to fully participate in all industrial and systems engineering discipline areas at some level, even while advanced courses in certain areas may not be immediately accessible to all graduate students.

Many graduate students who are actively engaged in research receive financial support through a combination of research and teaching assistantships and fellowships. Decisions about research assistantships are made by the individual faculty members and decisions about teaching assistantships are made by the department. Support is available on a semester or academic year basis. Stipends are approximately $20,000 (half-time or 20 hours per week) for an academic year of graduate study. Other levels of support are also possible. If an award is made, nonresident students usually qualify for tuition at the resident rate, at approximately $10,000 per academic year. Normally stipends are not immediately awarded to international applicants, but after admission and enrollment, an application can be made. Preference for graduate student support is given to Ph.D. students.

Students should direct questions about availability of financial support to faculty members in their in primary area of study. Awards and reappointments are highly competitive and are based upon a student's academic record, prior performance, the ability to serve, and upon an assessment of the student's potential contribution to the research and teaching goals of the program.

Industrial and systems engineers have many opportunities for employment and service in industrial, government, research, and public service organizations. Employment opportunities are among the most varied in the engineering field. Industrial and systems engineers are employed by manufacturing and energy firms, government agencies, and service organizations such as airlines, banks, hospitals, health care groups, and consulting companies.

The Ph.D. is a gateway toward careers of learning and creation. Employers typically hire people with doctorates to run laboratories, create research directions, and supervise other engineers at the boundaries of knowledge. Ph.D.-level researchers generally enjoy great freedom and tailored work environments as they explore and learn to help create new visions of tomorrow. A Ph.D. opens up academic, research, and entrepreneurial possibilities limited only by one’s drive and creativity. Positions are often found through announcements in trade journals, international conferences, and specialized job-posting services. Students often work with faculty to identify and apply for appropriate positions. It is rare that students do not find an appropriate position before completing their thesis.
