I am head of the Knowledge Systems group at the Department of Computer Science at the Technical University of Dresden. My scientific interests are, broadly speaking, in the area of intelligent information 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 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.

Finally, regarding that name of mine: It is written Krötzsch or Kroetzsch, but never Krotzsch. The vowel ö (umlaut o) is pronounced long, as in Gödel and Björk. It's roughly like the ea in the English pearl or the eu in French peu (try making these sounds while forming your mouth as when saying an o). You could try to combine the sounds that appear in the following words:
chrome + pearl + match
Or simply call me Markus.
