I am professor for Knowledge-Based Systems at the Institute for Theoretical Computer Science of the Faculty of Computer Science at TU Dresden. The professorship is also part of TUD's Center for Advancing Electronics. My scientific interests are, broadly speaking, in the area of intelligent knowledge management systems. I have made contributions to lightweight and rule-based ontology languages, query answering, reasoning complexity, and content management and integration platforms for the Web of Data. This has led to many publications, but also to introductory texts (including two textbooks) and other teaching materials. I also co-edited the W3C Web Ontology Language standard OWL 2.
My most important applied work at the moment is Wikidata. Other projects I have contributed to include the semantic content management system Semantic MediaWiki and the highly efficient ELK ontology reasoner. Behind each of these projects are a number of truly outstanding people with whom I have had (and still have) the pleasure to work.
