Writings are often the visible output of research projects that involve many years and much collaboration. These span a range of categories – AR/VR, Material Exploration, Data and Computation, Architecture – reflecting my general interest in ways that digital technologies can support artists and designers, as well as my belief in the critical role that art and design can play in shaping technologies and positive futures.
