Highly-respected performance artist, session musician, and music educator, Christa is as comfortable lending her talents to the orchestra pit as she is in character wardrobe, playing on stage with Led Zeppelin or playing solo violin and strolling the stage with Expressions Dance Company. One of Topology’s founders, a steadying influence and strong driving force towards the shared common goal, Christa has helped steer Topology from the start, emerging as Finance and Education Director. When she’s not playing with Topology, she performs a wide range of chamber music, her long-held passion. She also plays orchestral music with the Queensland Symphony Orchestra, gigs with bands and teaches violin in her private studio and as guest at various education institutions. Christa studied at the University of Queensland (BMus Hon 1991) with Elizabeth Morgan, in London (1991 – 1993) with Emanuel Herwitz of the Melos Ensemble and at the Queensland Conservatorium with Carmel Kaine, obtaining her Master of Music in 1996. In London, she played with the Olyver Gypsy Ensemble.
