Dr. Mokhtarian is the inaugural holder of the Clifford and William Greene, Jr. Professorship in CEE. She has specialized in the application of rigorous quantitative methods to the study of travel behavior for more than 40 years, authoring or co-authoring more than 200 refereed journal articles, technical reports, and other publications. A key research interest has been the impact of telecommunications technology on travel behavior, with additional interests in land use and transportation interactions (especially the influence of the built environment on travel behavior, after accounting for self-selection), attitudes toward travel itself, multitasking, travel time budgets, induced demand, and congestion-response behavior.
