BioJEAN-GUILLAUME WEIS was born in 1969 in Luxembourg. He began his dancer career at Ballet Contemporain de Bruxelles (1985-1988). At the age of 19 he received the Jugendpreis IKB for Ballet in 1986. Afterwards he danced and performed with many artists worldwide, among them the Mark Morris Dance Group in Brussels and New York from 1988 until 2003, Pina Bausch Tanztheater-Wuppertal (1994-1998) and Tanztheater Basel under direction of Joachim Schlömer from 1998 until 2001.

In 1998, Jean-Guillaume started focusing on choreographing and created his first piece that year. His various original productions explore dance and choreographic tradition as well as the concept of dance theatre and redefines its form and its substance. The result is experiment-based research that produces various works in an intense choreographic and theatrical flow, with a specific focus on artistic diversity and occasionally involving a range of different media. By raising questions about the subconscious and the imaginary facets of contemporary issues, Jean-Guillaume's productions fuse respect for tradition with the urge to question the underlying codes and roots of dance today. His activity as a choreographer extends to staging and choreographing for plays and film, exams, awards, and competitions.

In 2002 he founded his own company – Dance Theatre Luxembourg. Numerous works were premiered and shown in many countries since the establishment of the company. Recent works include Seasons, Driven, Flock and Bucketful of Dreams. In his work Jean-Guillaume Weis likes to ask dancers to contribute their own dance-material, which results in choreographies that vary from the concept and theme depending on who is involved. This combined workflow influences Jean-Guillaume's perception and choices when creating new works, and this signature style unmistakably identifies each of his pieces as his, even when they may look quite different from each other.

As a guest choreographer, Jean-Guillaume Weis choreographed various pieces for Spellbound Contemporary Ballet (Rome), Théâtre National du Luxembourg, Artist Bea de Visser, ZuKT at Hochschule für Musik und Darstellende Kunst Frankfurt am Main and Oklahoma University, among others.

Jean-Guillaume himself is a passionate teacher for Ballet and Contemporary dance, and he founded the Danzschoul Wellenstein in 2013. He regularly teaches classes, workshops, and develops choreographic projects in universities, conservatories, and prestigious dance schools. Mr. Weis has been teaching Ballet and Contemporary dance in institutions such as the Baryshnikov Arts Center in New York, HJS Amsterdam, and ArchiTanz Tokyo, among others.

In 2015, Jean-Guillaume Weis received the Ordre du Mérite du Grand-Duché de Luxembourg.
