She has since appeared with numerous international orchestras and plays regularly in the Bayreuth Festival Orchestra.

Her pupils have gone on to win positions in prestigious orchestras in Marseille, Düsseldorf, Kassel and Berlin. She is also active in the Musikkindergarten Berlin – a unique project initiated by Barenboim – and has contributed to developing the pedagogical ideas that are at its very foundation.
