Urs Dierker is the founder of Circular Costume Design (CCD) and a costume textile artist for screen and stage productions in Europe and North America. CCD is an innovative initiative that Dierker realizes with academic and cultural sector partners to develop solutions for sustainability and costume design. 

At Aalto University in Finland, Dierker worked with material scientists to explore new applications of biomaterials for costume. This led to a collaboration with the Finnish National Opera and Ballet and the Opera Leipzig, Germany. In partnership with the Opera Leipzig and the Icelandic Opera, Dierker received the 2022 FEDORA Next Stage grant to develop sustainable approaches to costume design. This multi-year project is part of Dierker’s doctoral research.
