Trained as an operatic coloratura, Stephanie uses her voice as a mechanism of avant-garde performance art, creating 'maniacal shifts of vocal production and character… like an icepick through the skull' (composer Jason Eckardt). Her work has been described as 'crystalline' (The Financial Times), 'divinely deranged' (Herald Scotland), and ‘performance art of the highest caliber’ (PopMatters.com). She has performed at Roulette Intermedium, Sound Scotland, Kings Place, Southbank Centre, Helsinki Music Centre, and Casa da Música, and collaborated with Riot Ensemble, the London Sinfonietta, International Contemporary Ensemble, and Post Coal Prom Queen.

An established multidisciplinary artist, Stephanie has collaborated as a soprano and composer with contemporary artist Jesse Jones to co-create Mirror Martyr Mirror Moon, a film presented at the Ikon Gallery in Birmingham in partnership with the National Gallery in London, and The White Cave, a film presented at the 2026 Singapore Biennale. Mirror Martyr Mirror Moon received a five-star rating from The Guardian, noting the 'mesmerising film... The sound (and vision) is stunning, harrowing, agonising, sonorous and then garbled, stoppered, and running, as it seems, backwards.' Stephanie has also collaborated with Jesse Jones and electronic musician and composer Alistair MacDonald to co-create AtLantis AtLand, a site-specific stage work for voice and electronics at the 2026 Open Ear Festival, which was described by Clash Magazine as 'one of those rare performances that fundamentally alters how you perceive a place.' Stephanie has collaborated with video artist and photographer Oana Stanciu and composer Tom W. Green to co-create Anthropocenic Garden, a multidisciplinary exhibition for film, music, and dance, commissioned by and presented at the Hidden Door Festival. She has also collaborated with Alistair MacDonald and author and activist Jessica Gaitán Johannesson to co-create Soroche, a work for music, spoken voice, and film, commissioned by and presented at the Edinburgh Futures Institute.

A prolific recording artist, Stephanie released albums Quaking Aspen, Georges Aperghis' 14 Récitations, Don't Add to Heartache, and Ecstatic Visions to international critical acclaim. Quaking Aspen was hailed by PopMatters.com as 'a bold artistic statement that’s exciting and innovative... a magical, intense, and deeply satisfying journey.' 14 Récitations was described as a "tour-de-force... sportive vocal adventure of impressive proportions,' (Concerti.de) and a record in which 'virtuosity is complemented by total commitment and vivid imagination.' (Bandcamp.com) Don't Add to Heartache was celebrated as 'an impassioned exploration of sound, space, and the relationship between nature and humanity... a fiercely inventive body of work that urges listeners to consider their relationship with nature in an increasingly artificial world.' (The Skinny) And Ecstatic Visions was acclaimed as 'a thing of genius... a deeply atmospheric, flawlessly executed record that pairs the mythical with the modern.' (PopMatters.com)
