​For various years Thomas Steyaert worked with Wim Vandekeybus/Ultima Vez and danced in Blush (creation 2002), Sonic Boom (creation 2003) and the reprise of Les Porteuses de Mauvaises Nouvelles (touring 2005). He also played in Puur (2006) and Spiegel (2008). In 2006 he decided to make his own work and founded Ponyhill vzw, a collective of artists active in dance, performance, music, photography, film and visual art. From 2007 until 2010, Thomas Steyaert was part of a cultural exchange program between Belgian artists and artists from the Democratic Republic of Congo, organized by the KVS (Royal Flemish Theater, BE) under the artistic direction of Jan Goossens and in co-operation with Ultima Vez. Since 2009 Thomas Steyaert is working with Raul Maia on an ongoing artistic process based on the development of a real-time, non-representational kinetic movement system. Until now the research resulted in three stage performances, The Ballet of Sam Hogue and Augustus Benjamin, The Ballet of Albertina Macchiavello, Johnny McLay and Ignatz van Stereo and The Ballet of Paul Ace and Sunny Lovin, in many site specific performances and in several video works. Within the same context he also develops his individual approach and stage works. In 2014 Thomas was invited by WASP (Working Art Space an Production) in Bucharest to create score#21 - Method of Elimination.  In 2015/2016 he was again invited by WASP and l'AGORA in Montpellier to make Solatium. The music was made by the Belgian post-metal band, Amenra. Thomas regularly works as a choreographer with Cirk La Putyka, a contemporary circus company based in Prague under the artistic direction of Rosta Novak. The last few years Thomas became a collaborator with Haris Pasovic, director of East West Theatre Company in Sarajevo, BIH. Together they worked on Roses for Anne Teresa / Football Stories, The Conquest of Happiness and A Century of Peace after the Century of Wars. He also works closely together with Nermin Hamzagic (Insurgent M.K. and Welcome) and Selma Spahic (Kokos, Liliom, Moja Fabrika and Romeo I Julija), two artists based in Sarajevo. In 2016 he founded the collective 'Moving Island', in Sarajevo. The collective focuses mainly on socially engaged artistic work. Together they created Whispering dreams, at “Zavod” (institution for juvenile criminals) and Zenica 2.0 at “Dom Porodica” (center for children without parental care). In 2017 Thomas created If someone speaks, it gets lighter, at BNP Zenica (Bosnian National Theater), an interactive theater show on loneliness and solitude. In 2018/2019 Thomas was invited by DOT504 dance company in Prague to create score#44 - Methods of Excavation. Thomas also gives workshops, paints/ draws and creates soundscapes. In 2019 he had his first solo exhibition with paintings, prints and drawings at the National Gallery of Bosnia and Herzegovina. His work has been shown in theaters and festival in Europe and abroad.
