Gareth is a writer, dramaturg, translator, and director originally from the UK. They are interested in a collaborative multi-media approach to live performance, embracing how this interdisciplinary approach can enrich queer representation within opera and music-theatre. For them, opera is a radical space in which different cultures, identities, time periods, technologies, and realities can all enter into dialogue with one another - and emerge transformed.

Gareth graduated from Trinity Hall, the University of Cambridge with a BA Hons in English Literature, and an MPhil in Screen Media and Cultures, where they researched the relationship between opera and cinema. Following on from this, they also completed an MA in Opera Making and Writing at Guildhall School of Music and Drama (subsequently undertaking an Artist Fellowship) and an MFA in Dramatic Writing at Tisch School of the Arts, New York University (where they were awarded a Dr Kenny Encouragement Fund Scholarship, and NYU’s Venable Herndon Award for Excellence in Screenwriting). In 2022, they were awarded a Scholarship by the Daiwa Anglo-Japanese Foundation to study Japanese at Waseda University, and to develop their work while living in Japan. Gareth was also recently part of the inaugural Up Next: Future Film Curators’ Lab with cross-disciplinary film, performance and moving image festival Queer East.

Gareth’s work has previously been supported by a Foreign Affairs Theatre Translator Mentorship, as well as by residencies and workshops with Snape Maltings in Aldeburgh, the British Centre for Literary Translation, Shakespeare’s Globe, LOD muziektheater in Ghent, Belgium, Theaterakademie August Everding with the Young Opera (JOiN) of the Staatsoper Stuttgart, Germany, Académie du Festival d’Aix in Aix-en-Provence, France (all facilitated by the European Network of Opera Academies), Theater Nohgaku in Tokyo, Japan, and the Banff Centre for Creativity and the Arts in Canada.

They have previously guest lectured at Tokyo University, worked as a Teaching Assistant on aesthetic history at New York University’s Tisch School of the Arts, a Supervisor and Seminar Leader at Guildhall School of Music and Drama (for both the Performance and Creative Enterprise BA, and the Opera Making and Writing MA), and as a Directing Mentor (for both Aldeburgh Young Musicians and a collaborative project between Hampstead Garden Opera and The Latymer School).
