Research Interests

Geographic Information Systems, Remote Sensing, urban planning, urban geography, travel demand modeling, transportation planning, public transportation, environmental impact, Latin America, Distance Learning

My research interests are fairly broad in nature. However, the bulk of my research has been related to GIS, urbanization and transportation. Prior to my entry into academian,  I worked as a transportation planner and a public transportation manager for approximately 10 years. This knowledge and experience has greatly influenced my research as an academician. Currently I am involved in reseaerch concerning watershed management, vehicle related air pollution, and GIS usability.
