My research and teaching interests lie at the nexus of hazards, transportation, and geographic information science. I am interested in all three of these areas separately, but topics that incorporate two or three are especially interesting. A prime example is the role of transportation in emergencies, which may involve relocating people to safety or deploying resources to a disaster site. My primary focus is advancing the field of regional evacuation analysis. The methods that I've developed are explicitly geographic and rely on integrating techniques in operations research and geographic information science.
