I would characterize myself as an HCI researcher with a focus on crowd computing; or popularly known as crowdsourcing. On my PhD I worked on novel mobile and pervasive applications for intra-family communication as well as, on a methodological side, improve the experience sampling method. On my PostDoc I applied some of the methodological findings to support patients suffering from obsessive compulsive disorder. Currently my research activities can be captured in the following title: Design for Crowdsourcing & Crowdsourcing for Design. What I mean with the first part is how designers can improve existing crowdsourcing platforms and by the second part I am interested in developing crowdsourcing platforms to support designers. Past research activities included context-ware computing and evaluation of mobile, location-based ads with the help of a mixed-reality setup. I am assistant professor at the Industrial Design Department of Eindhoven University of Technology in the Netherlands and founding member of Ambianti.
