Since 2015, Harriet has been collaborating with Dr Verity Clarkson to develop a strand of research around their mutual interest in design as the focus for international diplomatic exchanges. This led to the one-day symposium held at University of Brighton in November 2015 entitled 'From "Soft" to "Hard" Power? Changing Visions of Diplomacy by Design from 1945 onwards', supported by the University’s Internationalising Design History research cluster and School of Humanities. The papers from this symposium will be published as a special issue of Design and Culture journal entitled Design as an object of diplomacy post-1945 in July 2017.
