Ph.D. Degrees

The Doctor of Philosophy in Industrial Engineering, and the Doctor of Philosophy in Systems and Engineering Management programs are research-focused degrees that prepare graduates for university teaching and research, industry research and leadership, and consulting.

With the counsel of a graduate advisor, students are expected to design individualized academic programs. The doctoral program requires a minimum of 60 hours of coursework beyond the bachelor's degree, which may include up to 15 hours constituting a minor area. At least 12 hours of doctoral dissertation enrollment are also required for the doctoral degree. Transfer credits from a master's degree program are determined by the student's graduate advisor and the graduate school, with a maximum of 30 transfer credits allowed.

Ph.D. programs incorporate courses taken in each of the five specialty areas below.

  • Engineering Management: Systems theory, decision theory, industrial cost analysis, advanced engineering economics, performance improvement in organizations, project management, and productivity management.
  • Ergonomics and Human Factors Engineering:Occupational biomechanics, work physiology, industrial ergonomics, environmental hygiene, cognitive engineering, human performance, human computer interaction, and occupational safety.
  • Manufacturing and Quality Assurance: Manufacturing engineering and design, computer integrated manufacturing/CAD/CAM, process analysis and economics, automated manufacturing and process planning, programmable control systems.
  • Operations Research:Simulation modeling, scheduling and sequencing, just-in-time production systems, inventory and production control, linear and nonlinear programming, network analysis, artificial intelligence and expert system.
  • Statistics and Quality Assurance: Design of experiments, statistical data analysis, reliability and maintainability, on-line and off-line quality assurance, and total quality assurance.

The Ph.D. in Systems and Engineering Management (Ph.D. SYEM) is offered both on campus and by distance education while the Ph.D. in Industrial Engineering (Ph.D. IE) is offered on campus only. Details regarding admission and degree requirements can be found in the IMSE graduate handbook.
