Introduced to the Petits Chanteurs à la Croix de Lorraine in Epinal, trained at the Maîtrise Notre Dame de Paris, and then at the Conservatoire à rayonnement régional de Paris in ancient music, she founded in 2012 her ensemble, Tictactus, with two theorbists friends, Stéphanie Petibon and Olivier Labé. Oratoria alto soloist, she is regularly invited by great international orchestras, such as the Royal Liverpool Philharmonic, the Rotterdam Philharmonic Orchestra and the Tafelmusik Baroque Orchestra. She also creates effervescent recitals with harpsichordist Jean-Luc Ho and Philippe Grisvard.

From medieval to contemporary music, from concert to the scene, she regularly sings with Les Correspondances (Sébastien Daucé), Pygmalion (Raphaël Pichon), Les Arts Florissants (Paul Agnew) and she performed with Gérard Lesne, Patrick Cohën-Akénine, Rachid Safir and the Solistes XXI, Ophélie Gaillard and Pulcinella, Vaclav Luks and Collegium 1704, Le Poème Harmonique, Les Paladins, the Ensemble Intercontemporain…

In 2018, she made her debut at the Aix-en-Provence festival as Sorceress and Spirit in Dido and Aeneas by Purcell, as well as at the Carnegie Hall in New York as a Berliozian heroin conducted by Sir John Eliot Gardiner, after working with him on Monteverdi’s three operas in 2017 (as Messagiera, Penelope, Arnalta) on an unprecedented European tour that included a stop at La Fenice in Venice.

She worked with him once again in 2019 in the roles of Junon and Ino in Semele by Haendel, the opportunity for new debuts, this time at the Scala in Milan. And then once again in 2023, as Cassandre, in Les Troyens by Berlioz.

Her first solo album, Perpetual Night, released in 2018 with Les Correspondances by Harmonia Mundi, has received a flurry of international awards, including the Diapason d’Or of the Year in the ‘vocal baroque’ category, the Choc of the Year from Classica magazine, a Diamant from Opéra Magazine, the 2018 German Record Critics’ Prize and the 2019 ‘Caecilia’ Prize from the Belgian Union de la Presse musicale. Part of this programme was brought to the stage by Samuel Achache, in the show Songs.

2021 opens the ball of her first incarnations of Geneviève explored through various productions of Debussy’s Pelléas and Mélisande, again in Rouen and then at the Théâtre des Champs-Élysées and with François-Xavier Roth’s Les Siècles, each time directed by Eric Ruf. Cornelia’s turn was in 2022 in Giulio Cesare by Haendel conducted by Philippe Jaroussky, before addressing  Britten (A Midsummer Night’s Dream, Hippolyta) in Rouen, and then Poulenc (The Breasts of Tiresias) and Stravinsky (The Nightingale) at the Théâtre des Champs-Élysées in 2023/24 between two recitals of songs and lieder with pianists Anne de Fornel and Adam Laloum, and between two new productions with Les Correspondances!

Among the upcoming stage productions are Cupid and Death by Locke at the Théâtre des Bouffes du Nord and Théâtre de Caen, and David and Jonathan by Charpentier for a promising Pythonisse…
