I consider service to be a central component of a career in academia. On this page, I compiled a list of selected professional activities, committee memberships, reviewing activities, and invited talks (for conference talks see my publication page).  I do regular reviews for various venues including ACM CHI, ACM UIST, ACM Ubicomp, ACM DIS, ACM IUI, INTERACT, ACM ISS, ACM MobileHCI, NordiCHI, ACM VRST, IEEE VR, and various top journals. In addition, I serve as a reviewer for DFG and BMBF proposals, other European science foundations, and I am also a member of scientific advisory boards for projects on the 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 was the program co-chair for ACM ITS 2015 and ACM ITS / ISS 2016 and served as the chair of the steering committee of ACM ISS.
