Kathleen Stewart

Associate Professor, Director of CGIS

Kathleen Stewart is Director of the Center for Geospatial Information Science and works in the area of geographic information science with a particular interest in temporal GIS. This includes topics such as moving objects research (e.g., space-time trajectory modeling and space-time scheduling) and event modeling for dynamic GIS. She is interested in mobility and big geospatial data, and currently investigates movement and mobility for a number of different application domains, for example, public health and geospatial intelligence. She is also interested in modeling geospatial semantics including geospatial ontologies and their role for geographic information system design, and spatiotemporal information retrieval, i.e., computational methods for automatically acquiring meaningful space-time information from text sources. She teaches in the areas of spatiotemporal data modeling, geographic database design, geovisualization, and fundamentals of geographic information science. At the University of Maryland, Dr. Stewart is a member of the Program in Oncology at the University of Maryland Marlene and Stewart Greenebaum Comprehensive Cancer Center and also collaborates with researchers at the Institute for Global Health, the Center for Substance Abuse Research, the School of Public Health, and START among others. Support of her research has been provided by agencies including the National Science Foundation and the National Geospatial-Intelligence Agency among others.

Dr. Stewart serves as a member of the Mapping Science Committee of the National Academies of Sciences, Engineering and Medicine and the Board of Directors for the University Consortium of Geographic Information Science. She is a member of the editorial board of The International Journal of Geographical Information Science (IJGIS), Computers, Environment, and Urban Systems, Transactions in GIS, Geographical Analysis, and the open-access journal Journal of Spatial Information Science (JOSIS)

She is a steering committee member for the International  Conference on GIScience (e.g., GIScience 2016) and the International Conference on Spatial Information Theory (e.g., COSIT 2017) She served on the organizing committing for the Symposium on Human Dynamics Research at the AAG 2016 in San Francisco and served as program co-chair for the International Conference on Geographic Information Science, GIScience 2014 (with Matt Duckham and Edzer Pebesma)  held in Vienna, Austria.
