I am an Associate Professor (Universitetslektor, Docent) 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 have been awarded the academic qualification Docent in Computer Science from Linköping University. 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 four best research paper awards (ESWC 2009, ESWC 2015, ISWC 2017, and Semantics 2018).
