About Me

0 people like this post.

I am an Assistant Professor (Universitetslektor) at the Department of Computer and Information Science of Linköping University. I hold a Ph.D. in Computer Science from the Humboldt-Universität zu Berlin, and worked previously as a postdoctoral research fellow at the Cheriton School of Computer Science at the University of Waterloo and, thereafter, at the Hasso Plattner Institute, Potsdam. I am interested in problems related to the management of data and databases. My focus in this broad context is on data on the Web and on graph data, as well as on problems in which the data is distributed over multiple, autonomous and/or heterogeneous sources. Regarding these topics, my interests range from systems-building related research (e.g., efficient storage of data, query processing, and query optimization) all the way to theoretical foundations (e.g., complexity and expressive power of query languages). I was honored with the SWSA Distinguished Dissertation Award in 2015 for my Ph.D. dissertation “Querying a Web of Linked Data: Foundations and Query Execution” and I have received two best research paper awards (ESWC 2009 and ESWC 2015). I am leader or contributor of several open source projects, most notably SQUIN, which is a novel query processing system for the Semantic Web. I co-organized international research workshops, served on multiple program committees, and participated as an invited expert in the provenance incubator group and the provenance working group of the World Wide Web Consortium.

In this blog I write about events, ideas, and results related to my research. For more information about me, including my publications, refer to my Website at http://olafhartig.de.
