AJ is a performer, conductor, and creative producer. She is the Artistic Director and founder of artist-led organisation, Luminescence, which comprises both Luminescence Chamber Singers and Luminescence Children's Choir.

Under AJ’s leadership, Luminescence has earned a reputation as a uniquely versatile ensemble, performing repertoire that spans renaissance polyphony, folk song, and contemporary art music, and increasingly working across amplified and un-amplified forms. Recent highlights include performances at Phoenix Central Park and Sydney Opera House, collaborations with the Australian Chamber Orchestra, and a major new music project developed in collaboration with GRAMMY Award winning composer and producer William Brittelle and sound designer Tilman Robinson.

In addition to performing with Luminescence, AJ performs regularly as a freelance soloist, recitalist, and ensemble singer, including engagements with Cantillation, Sydney Cantata Project, Pinchgut Opera, St James’ Choir King Street, and a range of independent projects. Highlights have included recital programs with Roland Peelman AM (director and pianist) and Ella Luhtasaari (piano), performances of David Lang’s death speaks, and AMPLEYA, a multimedia collaboration with pianist Rasa Daukus and photomedia artist Genevieve Swifte.

In 2023 AJ was awarded the APRA AMCOS Art Music ACT Luminary Award. She was Chair of the ACT Minister’s Creative Council from 2022 - 2023, and continued to serve as a member of the Creative Council until July 2025. In 2024, AJ was the Associate Artist at Canberra International Music Festival, and a guest conductor of Gondwana Voices at National Choral School.
