"Kathleen Stewart is interested in modeling geospatial semantics, including event modeling for dynamic GIS, moving objects research, 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. She received her Ph.D. in Spatial Information Science and Engineering from the University of Maine. Dr. Stewart's research interests relate to modeling geospatial semantics, including moving objects research, event 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, geovisualization, 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 is the program co-chair for the upcoming International Conference on Spatial Information Theory (COSIT 2009) to be held in Aber Wrac'h, France in September 2009. In Fall 2008, she co-organized a workshop on Temporal GIS: The Past 20 Years and the Next 20 Years at GIScience 2008 and is a co-editor of the special issue of IJGIS on this topic. Kathleen 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 the 2nd International Workshop on Semantic and Conceptual Issues on GIS (SeCoGIS 2009), The 3rd International Conference on Geospatial Semantics (Geos 2009), the 12th International AGILE Conference on Geographic Information Science (AGILE 2009), and GIScience 2008 among others. She serves on the editorial board of The International Journal of Geographical Information Science (IJGIS), Computers, Environment, and Urban Systems, the GIS section of the journal, Geography Compass and the new open-access journal Journal of Spatial Information Science (JOSIS). She currently serves as vice-chair of the Research Committee of the University Consortium for Geographic Information Science (UCGIS).
