On 1 December 2016 I was appointed as Dean of the Faculty of Science at VU University Amsterdam. Beofre that I was for two years Head of the Computer Science department.
I'm still 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.
After my entry in 2014 into the management ranks leadership of the Web & Media research group was taking over by Professor Lora Aroyo.
