My research interests lie in the domains of geographic information science, transportation geography, and urban geography. I am very interested in the applications of GIS techniques to investigate social and environmental problems.
My previous research focused on agent-based microsimulation of emergency evacuations, spatial analysis of crime patterns, network analysis of commuter patterns and facility locations, and vulnerability assessment. Currently, I am continuing my study on emergency evacuation and commute patterns. I am particularly looking at how different variables, e.g. evacuation zoning structures, evacuation sequences, spatial-temporal variations of evacuation population, human behaviors, affect the effectiveness of evacuation strategies at a micro-scale level.
