Passionate about the performing arts from a young age, Mathilde first trained in modern-jazz and then contemporary dance (Cunningham, Limon) as well as jazz on the flute. After completing a literary preparatory class at Janson de Sailly high school, she joined Neoma Business School to specialize in cultural project management. In parallel, she started theater by joining an improvisation troupe ("Les Nymproman's") and wrote and directed her first play, "The Four Seasons." She then joined the La Canaille company and performed in several productions ("The Wedding" by Chekhov, "Sauce for the Goose" by Feydeau).

During her studies, she spent part of her master's in Buenos Aires at UCA University and concurrently attended the theater training by Felicitas Kamien. Between 2020 and 2022, she completed several internships in communication and production: first for the Flamenca Ana Ramo company, at the Théâtre de Suresnes Jean Vilar, and at La Gaîté Lyrique. She completed her end-of-studies internship in directing on a participatory creation project and cultural mediation.

Graduated with an MSC in Cultural and Creative Industries, she joined the Grand Orly Seine Bièvre Conservatory in September 2023, where she studied under Colette Tomiche, Claire Cafaro, and Philippe Tarride. In November of the same year, she joined ALTER EGO (X) on a civic service as an assistant for European cultural and artistic projects, working notably on the GRESYS, Live On!, and Closing The Gap projects.
