    I'm a professor at the university of Würzburg. Prior, I was a senior researcher - here - at the university of Kassel. I'm working in the area of Data Mining, Semantic Web and Mining of Social Media. I'm directing the BibSonomy project at the KDE group of the university of Kassel. I started my research at the AIFB Institute at the University of Karlsruhe where I was working on text mining, ontology learning and semantic web related topics.
