Born in South Korea and raised in France, Mathis Joubert is a French dancer and creator whose work bridges contemporary ballet, breakdance, fashion, film, and large-scale performance. His signature language, The Balletbreak, emerges from a dual foundation in classical ballet and B-boy technique, combining precision, musicality, and explosive physicality.

He began as a self-taught street dancer, founding his first crew Slybreak Danse before entering professional training in Toulouse, where he studied classical ballet at VM Ballet (2013–2016) while simultaneously deepening his breakdance foundation with ABD-L of the world-champion Vagabond Crew at Break’in School.

During these years, he earned several major distinctions, including:

• Best Talent Award – AmsterDans International Competition

• 1st Prize – #lamiastoriadidanza (Capezio & Danza in Fiera)

• 1st Prize – Get Up et Fais Ton Truc (Jamel Debbouze & Carrefour)

• 2nd Prize – Prix d’Europe (Contemporary Solo Senior)

In 2016, Mathis moved to New York on full scholarship to train at Peridance Capezio Center, before joining The Alvin Ailey School on a two-year full scholarship. 

He continued expanding his technique through additional scholarships at Complexions Contemporary Ballet, Alonzo King LINES Ballet, Jacob’s Pillow Contemporary Program, Visceral Dance Chicago, and the École Nationale Supérieure de Danse de Marseille. This diverse, high-level training shaped the foundation of his hybrid artistic identity, blending classical precision, contemporary nuance, and the explosive energy of breaking, a language he calls The Balletbreak.

His professional career began in New York, where he performed with Arch Ballet at the New York City Center and the Eden Fine Art Gallery. During this period, he also assisted choreographer Michael Blake (former Director of the Joffrey Ballet School) at Steps on Broadway and Peridance, and collaborated with renowned creators such as Christopher Huggins, Ray Mercer, Francesca Harper, Jennifer Archibald, and Brice Mousset. He was additionally featured in Nick Cave’s monumental exhibition The Let Go at the Park Avenue Armory, a critically acclaimed production that received a Bessie Award, one of the highest honors in American dance.

In 2019, Mathis joined Visceral Dance Chicago, touring internationally including a performance at the Santa Lucia Festival in Mexico. That same year, he became a dancer with Bad Boys of Ballet / SweetBird Productions, performing leading roles in major European tours such as Rock the Ballet, Romeo & Juliet, and Rock the Ballet X across Germany, France, Switzerland, and Belgium.

Mathis rapidly gained international visibility through major productions and televised events. He performed at the Darley Awards at the Dolby Theatre in Hollywood as principal dancer and choreographer for a private ceremony commissioned by the Sultan of Abu Dhabi. He appeared at the Riyadh Season Festival in Saudi Arabia, performing live in front of 13,000 people and for over 110 million viewers on Rotana Live TV alongside two of the Middle East’s leading superstar singers. In France, he danced in the national television program Un Été en France with world-renowned cellist Gautier Capuçon and Paris Opera Ballet choreographer Sébastien Bertaud, as well as in the Concert de Paris at the Eiffel Tower, broadcast internationally on Bastille Day.

His versatility also led him to the world of fashion and media, appearing in New York Fashion Week, Philadelphia Fashion Week, and Paris Fashion Week for FRED Jewelry at the Palais de Tokyo, as well as in editorial shoots for Beaux-Arts Magazine x CooKoon Paris. 

He has been featured in brand campaigns, commercials, editorial photoshoots, collaborations, and runway work for Adidas, Asus, Reebok, Uniqlo, Decathlon, Flotte, Outdoor Voices, Solid Homme, MPG Sport, Flexispot, Stade Français, Club Forfait, CPF, Pig & Hen, Beep Sheep Shamp, Bodyline Fitness, Covet Dance, Good Night 5tore, Gecko Hawaii, Funari New York, Tightans, Liberty Play, Naughty By Nature, Primaal, Sprigswear, Che21, and others.

Mathis’ screen credits include the Netflix series Bendo, Disney+’s Parallèles, TF1’s Mensonges, and Guillaume Canet’s feature film Astérix & Obélix : L’Empire du Milieu. He also appeared in music videos for Amir, YoYo Ibarra, and Fredrik Eklund.

In 2023–2024, Mathis joined "Verb" Ohio Contemporary Ballet as a company member and choreographer, while establishing himself as a teacher, mentor, and judge for international dance competitions such as Les Espoirs de la Danse and Bravissimo International Competition. He received notable offers from The Lion King (Paris), The Little Prince (Broadway), Ballet Hispánico II, Spectrum Dance Theater, Na-Ni Chen Dance Company, and others.

In 2024, he became a company member of BalletX, one of the most influential neo-classical companies in the United States, performing works by leading choreographers including Justin Peck, Marguerite Donlon, Stina Quagebeur, Amy Hall Garner, Matthew Neenan, Gregory Dawson, Take Ueyama, and Jennifer Archibald. With BalletX, he performs on major stages such as The Kennedy Center, The Joyce Theater, The Harris Theater, the Guggenheim, the Vail Dance Festival, the Laguna Dance Festival, and tours across the U.S. and internationally.

In parallel, Mathis continues developing his choreographic voice and multidisciplinary approach. In 2022, he served as principal dancer, choreographer, and show director aboard the expedition vessel Le Commandant Charcot (Ponant Cruises) in Antarctica, creating original productions and overseeing artistic planning. Today, Mathis stands at the intersection of contemporary ballet, breakdance, creation, education, and cross-disciplinary performance. His work reflects a commitment to artistic excellence, versatility, and the development of a hybrid movement language designed to inspire the next generation.
