I am active as a board member of User Modeling Inc. and was between 2007 and 2015 chair of ABIS, the German SIG on Adaptivity and User Modelling in Interactive Systems.
I serve as General Chair for the upcoming UMAP 2017 conference and was General Chair for the Hypertext 2016 conference. Further, I served as Program Chair for Hypertext 2014 and as Poster and Demo Chair for IUI 2015. Earlier, I served as Publicity Chair for CHI 2012 and have been involved in the organization committee of several other conferences.
I also reach out to the community and the general audience via tutorials, talks, interviews and articles.
Recently, I started to blog about my research activities. Stay tuned!
