After attaining a university degree in History, Yoann Gasiorowski trained at the Poitiers Conservatory which was run by Jean-Pierre Berthomier. In 2011, he performed Daniel Keene’s Untitled Monologue (Monologue sans titre) directed by Rodolphe Gentilhomme.

Then he played in Patio, a multimedia piece conceived by Cyril Teste and the MxM collective after We’re Not Here to Disappear (On n’est pas là pour disparaître) by Olivia Rosenthal. As part of the 25th class of the École supérieure de la Comédie de Saint-Étienne, he worked with Bruno Meyssat on improvising from objects and with Alain Françon on the interpretation of Chekhov’s opus, more specifically Uncle Vanya. Matthieu Cruciani introduced the students with the Marat-Sade, a work by Peter Weiss, and with Danton’s Death by Georg Büchner. Benoît Lambert had the students work on Débâcle(s), a piece Marion Aubert wrote specially for them. As a trained musician, Yoann Gasiorowki played the role of the Drummer in Jon Fosse’s Lilac as part of a carte blanche program by Marie-Ange Gagnaux et Clara Bonnet. He discovered the work of Thomas Bernhard through working with Michel Raskine who directed him in Le Réformateur.

Having left the school in 2014, he became a permanent member of the TDB, Centre dramatique national Dijon-Bourgogne Company for three seasons. There, he was part of several creations by Benoit Lambert: Molière’s Tartuffe or the Impostor (Tartuffe ou l’imposteur), Tartuffe 2.4 – a short piece for student classrooms, and La Devise by François Bégaudeau. At the same time, he continued training with Denis Guenoun and Stanislas Roquette in a workshop on the ‘‘scenic energy of thought’’ (« Énergies scéniques de la pensée »), and with Baptiste Guiton who directed him in Le bruit des taupes, a radio play by Magali Mougel broadcast on France Culture. At the Maison de la Poésie in Paris, he participated in the reading of Montrez-moi vos mains written and staged by the pianist Alexandre Tharaud.

In 2017, Yoann Gasiorowski played with two companies from Poitiers: Dennis Kelly’s Love and Money directed by Mathilde Souchaud, and 20 Novembre, a multimedia piece conceived by Angélique Orvain after a text by Lars Norén. He ran an interpretation workshop for the students of the Poitiers Conservatory, which was directly inspired by L’Abécédaire by Gilles Deleuze and Claire Parnet.

He became a pensionnaire of the Comédie-Française on the 2nd of January 2018, and made his debut in Goethe’s Faust, adapted and staged by Valentine Losseau and Raphaël Navarro. He also played in Les Ondes magnétiques written and directed by David Lescot.
