Gleaning the raw material of her work from the internet, books on natural sciences and photographic archives, Ntjam uses the method of assemblage – of images, words, sounds, and stories – to deconstruct hegemonic discourses on notions of 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.

These apparently heterogeneous discourses and iconographies are marshalled together in an effort to re-appropriate History while speculating on not-yet-determined space-time(s) – interstitial worlds where systems of perception and naming of fixed (id)entities no longer operate. From there, Ntjam composes utopian cartographies and ontological fictions in which technological fantasy, intergalactic voyages and hypothetical underwater civilizations become the matrix for a practice of emancipation that promotes the emergence of inclusive, processual and resilient communities.

Ntjam’s solo and duo exhibitions include Underground Resistance – Living Memories, The Photographer’s Gallery, London, UK (2022); and we’ll kill them with love..., CAC La Traverse, Alfortville, FR (2022); Molecular Genealogies, NıCOLETTı, London, UK (2021) and Allegoria, duo show with Kaeto Sweeney, Hordaland Art Center, Bergen, NO (2019).
