15. Rianne Petter and Mark Mulder by Scratching the Surface published on 2017-02-08T05:02:39Z Rianne Petter and Mark Mulder are designers and researchers from the Netherlands. The couple operates independent practices that span graphic design, research, writing, and education. Last fall, the couple visited Baltimore to lead a weekend workshop on design research of Maryland Institute College of Art's graduate graphic design department and I sat down with them at the end of the weekend to talk about their own practice, the role of research in the graphic design process, and the differences between the design discourse of the Netherlands and the United States.
