The Saint-Étienne-based artist, performer and writer’s practice combines sculpture, photomontage, film and sound. Gleaning the raw material of her work from the internet, books on natural sciences, and photographic archives, Ntjam uses assemblage—of images, words, sounds, and stories—as a method to deconstruct hegemonic discourses on origin, identity and race. Her work weaves multiple narratives drawn from investigations into historical events, scientific functions and philosophical concepts, to which she confronts references to African mythology, ancestral rituals, religious symbolism and science-fiction.
