On this page, I compiled a list of selected professional activities, committee memberships, reviewing activities & invited talks (for conference talks see my publication page). I do regular reviews for various ACM and IEEE venues including CHI, UIST, Ubicomp, DIS, IUI, INTERACT, IoT, ISS, MobileHCI, NordiCHI, TEI, TiiS, and various top journals. In addition, I serve as a reviewer for BMBF proposals, other European science foundations, and I am also a member of scientific advisory boards for projects on EU level. I am also actively involved in helping to lead several research communities. For example, I organized the first FTIR Multi-Touch Workshop held in Münster in 2007 and the follow-up bootcamp „Build-your-own“ Multi-touch Surface in conjunction with IEEE Tabletops 2008 in Amsterdam. I co-chaired ACM ITS 2010 in Saarbrücken and I am the program co-chair for ACM ITS 2015 and ACM ITS / ISS 2016 and served as a sub-committee chair for ACM DIS 2014 and ACM DIS 2016.
