North Dakota State University offers an interdisciplinary program leading to the Ph.D. degree in Transportation & Logistics (TL). The TL doctoral program is a joint effort of the Colleges of Agriculture, Food Systems, Natural Resources, Business Administration, Engineering & Architecture, and the Upper Great Plains Transportation Institute. The following departments are participating in the program: Agribusiness & Applied Economics, Civil Engineering & Construction, Industrial & Manufacturing Engineering, and Management, Marketing & Finance.

The TL doctoral program allows students to develop advanced knowledge and research skills in the rapidly growing fields of transportation and logistics. The Ph.D. program consists of three main components: a core curriculum of 25 credits, an area of concentration, and a dissertation. After completing the interdisciplinary core curriculum, students may enter one of three areas of concentration: (1) Logistics and Supply Chain Systems, (2) Transportation Economics and Regulation, and (3) Transportation Infrastructure and Capacity Planning.

This is a research-oriented degree that requires advanced skills in mathematical programming, statistics, and transportation modeling. Prospective students must have a high quantitative aptitude and be prepared to undertake rigorous graduate-level training in quantitative methods.
