PROGRAM OVERVIEW 

return to top

The Operations PhD program is a rigorous, four to five year curriculum designed to train students to become leading researchers and teachers at top business schools.

The PhD curriculum is designed to provide all students with a background in the literature and techniques used in Operations Management research. The program is highly quantitative in nature, and as such, incoming PhD students often have a background in economics, engineering, mathematics, or statistics. Although some students have completed graduate work prior to entry into the PhD program, this is not required. The program provides full financial support for all students.

The purpose of the doctoral program is to develop students into scholars who are well-prepared to investigate topical problems in operations management and to present their results at major academic conferences and in top scholarly journals. Students work closely with faculty members on cutting-edge projects. The scope of the faculty’s research interests and expertise is quite broad, addressing problems in supply chains and operations management in global manufacturing and service firms. Current interests include supply chain design and coordination, sustainability and reverse logistics, mass customization and quick response, retail operations, health care and humanitarian logistics, and global outsourcing and offshoring. The context for this research is broad and includes the banking industry, information services, the apparel industry, the airline industry, the automotive industry, and humanitarian nonprofit organizations.Below is a typical student’s timeline in the program: 

  • During the first two years of the PhD program, students focus on course work in order to develop the tools necessary to produce high quality research. Upon entry each student is assigned to a faculty member who acts as an advisor.
  • By the end of the first year, students take their qualifier exam. The exam consists of a written exam covering the courses taken in the first year of the PhD program.
  • In the summer after the first year, each student conducts original research under the supervision of a faculty member.
  • By the end of the second year, students take their comprehensive exam. The exam consists of a take-home written exam asking open‐ended research question(s) and an oral presentation of student’s second year paper.
  • After passing the comprehensive exam, students begin the second part of the program where they spend the majority of their time working on research.
  • In the third year, students focus most of their time on their dissertation. During this process, students benefit from close collaboration with faculty members.
  • The rest of the program is spent finishing the dissertation and preparing for the academic job market. 
  • Upon completion of the program, students are awarded a PhD in business administration.

 

PROGRAM CURRICULUM

return to top

The following document formalizes the course curriculum for the doctoral program in Operations. The purpose of a formalized curriculum is twofold. First, the curriculum is designed to prescribe a course of study so that a student will develop the ability to conduct scholarly research in the fields of operations and supply chain management. Second, the curriculum specifies the faculty expectations regarding the knowledge and skills that students must demonstrate in the doctoral qualifier and comprehensive examinations which are typically taken at the end of the first and second year of the doctoral program, respectively.

The Kenan-­Flagler Business School requires a minimum of 15 semester courses (45 hours) for the doctorate degree.  The 45-hour requirement should be regarded as a minimum.  Most students will take more than 45 hours to gain sufficient depth in an area of research interest. Likewise, the faculty may require an individual student to take more than 45 hours as a result of perceived deficiencies or performance on the doctoral comprehensive examination.

Sriram’s work has appeared in Management Science, Production and Operations Management, Journal of Operations Management, Decision Sciences, International Journal of Production Research and Supply Chain Management Review.

Sriram’s thoughts on the Ph.D program in Operations. “It has been my privilege to have been associated with the UNC Ph.D program. There are three key attributes I consider to be important in choosing a Ph.D program…(a) rigor of training (b) involvement and encouragement of the faculty mentor and the faculty group in general in the welfare of the PhD student and (c) the sense of camaraderie and community with fellow colleagues not just in the PhD program but beyond. The UNC PhD program excels in all of these parameters. (It) actively encourages students to take courses in disciplines such as economics, operations research and statistics that are important in building a strong toolkit for research. The faculty at UNC are phenomenal mentors who teach you how to apply the toolkit one acquires from the courses to research problems in the chosen field. Further, they often encourage the right mix of independence and guidance in the students’ pursuit of research agenda. Finally, a high degree of camaraderie and mutual support characterize the Ph.D cohort, and one has the opportunity to form life-long colleagues as one steps into academia. In addition, a distinctive feature of the program is its vast alumni base in the broader research community.”

His work has appeared or is forthcoming in the Journal of Operations Management, Production and Operations Management, Decision Sciences, Organization Science, and the Journal of Supply Chain Management, among others.

John commented on the Operations doctoral program. “(it) was distinct in that it provided rigorous training in OM analytical methods, while allowing a student to explore other methodological approaches. Such a combination is rather unusual in our field, and benefits researchers regardless of the primary approach the student pursues. The program allows students’ research interests to drive their choices in coursework and in faculty advisors. In addition to the excellent training and research environment, Chapel Hill is a wonderful place to live.”
