Daniel Cermak-Sassenrath is Associate Professor at the ITU, Copenhagen, and member of the Center for Computer Games Research (game.itu.dk) and the Pervasive Interaction Technology Lab (PitLab, pitlab.itu.dk). Daniel writes, composes, codes, builds, performs and plays. He is interested in artistic, analytic, explorative, critical and subversive approaches to and practices of play. Discourses he is specifically interested in, are play and materiality, play and learning, and critical play. He runs the University's monthly workshop series which is about electronics, mechanics, alchemy, interface devices and dangerous things. In his own practice, he makes interactive works which are shown at art exhibitions, academic conferences and popular events. Daniel is author of a monograph about play as a perspective in everyday computer use (transcript, 2010), and editor of a volume on the playful disruption of digital media (Springer, 2018).
