Bio

Professor Laurie Garrow's research addresses the development and application of advanced models of travel demand that integrate discrete choice, econometric, and market research methods to enhance understanding of travel behavior. Dr. Garrow earned her Ph.D. in Civil Engineering at Northwestern University, with an emphasis on travel demand modeling and airline passenger behavior. Her dissertation won first prize in the 2004 Aviation Applications Section of the Institute for Operations Research and the Management Sciences (INFORMS) and honorable mention in the 2004 Eric Pas dissertation competition sponsored by the International Association of Travel Behavior Research (IATBR). She is the 2009 recipient of the Council of University Transportation Centers-American Road & Transportation Builders Association (CUTC-ARTBA) New Faculty Member Award, one of the most prestigious awards given to an untenured faculty member in transportation that recognizes research and teaching contributions. Her teaching contributions have also been recognized via the institute-level award given by the Center for the Enhancement of Teaching and Learning, namely the CETL-BP Junior Faculty Teaching Excellence Award. She is also the recipient of a CAREER award that was jointly funded in 2009 by two programs at NSF - the Decision, Risk and Management Sciences Program and the Service Enterprise Systems Program.

Dr. Garrow has published articles on airline passengers' behavior, discrete choice methods, and studies that integrate discrete choice methods with urban planning or operations research problems. She is author of Discrete Choice Models of Air Travel Demand: Theory and Application, a text published in 2010. Dr. Garrow serves on the editorial boards of Transportation Research Part B, Transportation, and the Journal of Revenue and Pricing Management. Dr. Garrow has five years of industry experience, including four years as an analyst in the Research and Development Revenue Management Group of United Airlines and one year as an analyst in the Customer Science Unit of Mercer Management Consulting.
