about me

me

My name is Krzysztof Janowicz. I am a (full) professor for Geographic Information Science and Geoinformatics at the Geography Department of the University of California, Santa Barbara, USA. I am the director of the Center for Spatial Studies, former program chair of the Cognitive Science Program, one of two Editors-in-Chief of the Semantic Web journal, a Faculty Research Affiliate of the Center for Information Technology and Society, and the community leader of the 52° North semantics community. Finally, I am running the STKO Lab which investigates the role of space and time for knowledge organization. Before, I was an Assistant Professor at the GeoVISTA Center, Department of Geography at the Pennsylvania State University, USA. Before moving to the US, I was working as postdoctoral researcher at the Institute for Geoinformatics (ifgi), University of Münster in Germany for the international research training group on Semantic Integration of Geospatial Information and the Münster Semantic Interoperability Lab (MUSIL). Methodologically, my niche is the combination of theory-driven (e.g., semantics) and data-driven (e.g., data mining) techniques. The information below is not up to date, please check my Google Scholar account for publications. Finally, I am not related to the person with the same name that has an interest in WWII planes.
