Mathilde was raised in a multicultural environment, surrounded by her Russian grandfather, German grandmother, and Belgian parents. While growing up in the small city of Liège (Belgium), she took dancing classes for over a decade, trained in improvisation, and performed in a few plays throughout the years, coached by professional comedians.
Two months after graduating from high school, she took a leap of faith and made her way to New York City to pursue her dreams.
She first studied Meisner at The Acting Studio under James Price, then completed a "One Year Acting for Film Conservatory" at The New York Film Academy, and finally graduated with a "Two Year Acting Conservatory" diploma from The Lee Strasberg Theatre & Film Institute.
As of 2019, she's portraying Amity in the J.J. Abrams & Stephen King's Hulu series, Castle Rock.
Believing she's a full storyteller, Mathilde finds much joy and inspiration in her writing.
She won The Strasberg Works Award with her full length playSnow White & The Beast,tapped for production Off-Broadway, directed by Renoly Santiago (Hackers; Con Air; Daylight). She then wrote, produced, and played the lead in Rhythm in Me, a short film which ended up at The Cannes Short Film Corner as well as at The Palm Springs International ShortFest.
She’s also produced a couple of her other short plays (Prejudice; Ride) Off-Off-Broadway in NYC.
