Design has long established itself as an independent research competence. The New Experimental Research in Design (NERD) series seeks to provide a public platform to reflect upon and discuss the specifically experimental dimension of the field. The contributions from researchers from around the world exhibit a diverse and insightful range of approaches, giving rise to further debate and action in the rapidly evolving field. In times of multiple crises – the authors in this volume strive to find tactics of response. They introduce experiments into more-than-human design, co-species production, critical algorithmic immersion, feminist engagements with new materialism and more. From autoethnographic explorations to socially engaged methods, they challenge not just the role of design in these times, but the self-positioning of the designer.　 Experimental design Practice based research　 Design methods
