Doku draws inspiration from nature and how it adapts to changing conditions and environments. In her practice, she seeks to challenge anthropocentric perceptions of lived experience, opening space for a posthumanist perspective. She describes her creative processes as a form of surgical intervention; through deformation, reorganisation, transformation, multiplication, or division of forms, she strives to create something new.
