I am a professor of transportation in the Geography Department at the University of California Santa Barbara and director of the GeoTrans laboratory. From 1991 to 2004, I was Assistant, Associate, and Full professor of transportation in the Department of Civil Engineering at PennState University where I was also director of different research units. I chaired the Traveler Behavior and Values Committee (now serving as emeritus member) and chaired the Task Force on Moving Activity-based Approaches to Practice both of the Transportation Research Board of the National Academies in the United States. I also chaired the International Association for Traveler Behaviour Research in 2020 & 2021. I edited three books, authored and co-authored more than 350 papers and reports to sponsor, and served on a variety of editorial and research boards, peer review panels, and committees. I also co-founded and am the co-editor-in-chief (with Kouros Mohammadian) of the journal Transportation Letters. I have a Laurea in Engineering degree (today called magistrale 6 years with a thesis) from University of Calabria in Italy (1986), MS in Engineering from University of Michigan, Ann Arbor (1987), and Ph.D. from University of California at Davis (1991). Most of my research is in travel behavior dynamics, spatial analysis of surveys and big data, regional transportation models and microsimulation.
