I do research on sustainability-themed research questions around technological, economic, and infrastructure developments in urban transportation, and I frequently utilizes quantitative methods and GIS in my work. My current research projects study what many call “the three revolutions” of transportation: electric vehicles, connected and autonomous vehicle technology, and shared mobility. I look at questions about the diffusion of these different technologies, and how it may impact the sustainability of transportation. I have also done extensive work on the factors influencing interest in and the diffusion of electric vehicles, the relationship between gasoline prices and public transportation provision and usage, and on causes and effects of investments in urban rail transit. My teaching experience includes courses in human geography, human impact on the environment, internships in Law and Society and Public Administration, policy analysis, research methods in Geography and Public Administration, sustainable transportation, transportation methods planning, urban and regional planning, and world regional geography. I am the Undergraduate Program Director for SPAA. I have served as a reviewer for numerous major journals in geography, sustainability, and transportation, and I am currently the Chair of the Transportation Geography Specialty Group of the American Association of Geographers.
