About me

I'm a professor at the Web & Media group of the Department of Computer Science, VU University Amsterdam, and part of the Network Institute. My interests lie in knowledge engineering, web science, and e-humanities. I like to do interdisciplinary projects. Since 2002 I've spent a considerable amount of my time chairing W3C groups in the Data area. The last group I chaired was the RDF Working Group, for which I wrote the RDF 1.1 Primer.

Since October 2014 I'm acting as head of department. This leaves me a lot less time to do hands-on research work. Fortunately, I have an excellent successor as group leader of Web & Media, namely Lora Aroyo. One of the main challenges as head of department is to help shaping a joint "Amsterdam Department of Informatics" together with our colleagues of the Informatics Institute of the University of Amsterdam. Early 2018 we hope to move together into a brand new building near to our current premises (establising effectively a Science Park South). Check out our department wiki for details.
