"Kathleen Stewart Hornsby is interested in modeling geospatial semantics, including event-based modeling for dynamic GIS, reasoning about spatio-temporal phenomena over multiple granularities, and ontologies and their role for GIS."

Kathleen Stewart Hornsby is an assistant professor in the Department of Geography at the University of Iowa. Prior to this position, Kathleen served as assistant research professor with the NCGIA-UMaine. She received her Ph.D. in Spatial Information Science and Engineering from the University of Maine in 1999. Dr. Stewart Hornsby's research interests relate to modeling geospatial semantics, including event-based modeling for dynamic GIS, reasoning about spatio-temporal phenomena over multiple granularities, and geospatial ontologies and their role for geographic information system design. She teaches courses on spatiotemporal data modeling, geographic database design, and fundamentals of geographic information science. Support of her research has been provided by the National Geospatial-Intelligence Agency, the National Science Foundation, and the Disruptive Technology Office.

 

Dr. Stewart Hornsby is the program co-chair for the upcoming International Conference on Spatial Information Theory (COSIT 2009) to be held in Brittany, France in September 2009. Recently, she has served as chair of the Scientific Committee for the 2nd Conference on Ontology for the Intelligence Community ( OIC 2007) held in November 2007. In 2006 she co-organized the UCGIS Workshop on Computation and Visualization for the Understanding of Dynamics in Geographic Domains. She presented a keynote talk at the Workshop on Talking About and Perceiving Moving Objects at Spatial Cognition 2006. She is a member of numerous program committees including GIScience 2008, the 2nd International Workshop on Semantic and Conceptual Issues on GIS (SeCoGIS 2008), and the 11th International AGILE Conference on Geographic Information Science (AGILE 2008) among others. She serves on the editorial board of the GIS section of the journal, Geography Compass.
