Interests: GIS, Land Cover Change, Online Maps Social Media and Games, Social-Environmental Simulation, Director for the Service Learning Initiative, Cartography

Current Research: My interests revolve around three broad areas: 1) semantic uncertainty and formal ontology in analysis of land cover change, landscape history, and visualization. 2) how online maps, social media, and games form a nexus for spatial collaboration, social-environmental simulation, and decision making. 3) Service-Learning in cartography together with Columbus community partners.

Courses Taught:
Geography 5200/5200S-Elements of Cartography
