Biography

Patricia Mokhtarian is a Regents Professor and the Clifford and William Greene, Jr. Professor of Civil and Environmental Engineering (CEE) at the Georgia Institute of Technology.  Prior to joining Georgia Tech in 2013, she served 23 years on the CEE faculty at the University of California, Davis, after spending several years in regional transportation planning and consulting in Southern California.  Prof. Mokhtarian has specialized in the study of attitudinal influences on travel behavior for more than 45 years, and has authored or co-authored nearly 200 peer-reviewed journal articles, as well as numerous book chapters and research reports.  She is among the most highly-cited scholars in travel behavior research, with more than 41,000 citations and an h-index of 98 (Google Scholar). She is a past Chair of the International Association for Travel Behaviour Research, and received a Lifetime Achievement Award from that society in 2021.  Prof. Mokhtarian was elected to the US National Academy of Engineering in 2024, and serves on the editorial boards of ten transportation journals.

Research

A key research interest has been the impact of telecommunications technology on travel behavior (particularly teleworking adoption and impacts). Additional interests include the influence of the built environment on travel behavior, accounting for self-selection biases in modeling behavior, attitudes toward travel itself, time use and multitasking, incorporating attitudes into practice-oriented travel demand forecasting models, impacts of autonomous vehicles, congestion-response behavior, and subjective well-being.

Education
Ph.D. Northwestern University  1981
M.S. Northwestern University 1977
B.A. Florida State University  1975
Teaching

At the undergraduate level, Prof. Mokhtarian teaches upper-division probability and statistics, and at the graduate level she teaches statistical analysis, survey (questionnaire) design and analysis, and discrete choice modeling.
