I am currently involved in the European projects Grapple and Stellar, in which I work as local team leader and work package manager. I was general manager of the Prolean NoE, which finished successfully in 2008. I served as local chair of the Adaptive Hypermedia 2008 conference and as publicity chair of UMAP 2010 and UMAP 2011. Apart from project coordination, I supervise four Ph.D. students. Since 2007 I serve as the chair of the German SIG on Adaptive Systems and Interactive Systems ABIS.
My main research interests include Web personalization, user modeling, usability and HCI in general. In Grapple, we build a framework for user modeling, reasoning and profile enrichment using Web 2.0 services. Other research topics include Web usage analysis and the development of tools for Personal Information Management.

Since 2006 I contribute to the Dutch website Vegatopia.com as webmaster, reporter and moderator. Each month this site receives about 80.000 visits from about 50.000 unique visitors. In 2009 I initiated and coordinated the relaunch of the editorial Website in the Joomla CMS. I created the current technical setup, graphical design and navigational infrastructure.
I have always been engaged in cultural activities and music in particular. I play the piano, I sing and I write songs. From age sixteen until age twenty-four I worked as a background pianist at theatre 'de Harmonie' in Leeuwarden. I regularly give performances in the amateur music scene. As a natural consequence, I have been member of various boards and committees, including:
