Festival appearances include the Kuhmo Chamber Music Festival in Finland, the Biennale of Bern, Donaueschingen Festival and several concerts at the BBC Proms in London.

She's regularly invited to the Festival MESSIAEN au Pays de la Meije. 

She performs major works for ondes Martenot by Messiaen, Honegger, Milhaud, Varèse, Murail, Jolivet, Koechlin and Scelsi, among others, and is also very committed to contemporary music, improvisation and rock music (with such ensembles as Ensemble L'ITINÉRAIRE, collectif WARN!NG, duo with ErikM, FAUST, RADIOHEAD and ULAN BATOR) and to premiering radical new repertoire for the instrument.

In addition, she combines the ondes Martenot with contemporary art in performance and pieces alongside sculptures, voices, photographs and projections, in which she interrogates the notions of Utopia, vibrant and revealing animality, love, torture, and indifference.

Her recordings include the Dvd of Olivier MESSIAEN's Opera, SAINT FRANÇOIS D'ASSISE, conducted by Ingo METZMACHER, Giacinto SCELSI major work, UAXUCTUM, with the Philharmonic Orchestra and the Choir of Radio France, as well as TURANGALÎLA-SYMPHONIE with Toronto Symphony Orchestra, Gustavo Gimeno and Marc-André Hamelin on Harmonia Mundi Label.

Since 2016 she has been ondes Martenot professor at the Conservatoire National Supérieur de Paris.
