He has been playing the violin for 40 years and in that time has played all genres of music ranging from contemporary music to free jazz and free improvisation, live and in the studio.
As a avant-garde violinist/violist his main interest shifted towards contemporary improvised and new music as well as graphic scores by Gerhard Stäbler.
Studies with contemporary composers Paulo Brandão, Eurico Carrapatoso, Emmanuel Nunes, Pedro Figueiredo and Pedro M. Rocha.
The relationship with his instruments is focused in sonic and textural elements as well as the use of extended techniques.
Electronic music was an early influence on his approach to violin playing, which challenges traditional romantic concepts of the violin and viola through use of preparations and micro tuning.
Has founded and directs Variable Geometry Orchestra since 2000. A large ensemble where the conduction is operated by balancing the sound masses that travel in the acoustic space, dictating the construction of the realtime composition, and thus revealing the organized juxtaposition of specific instruments as mobile sound groups.
Active in different settings on the Portuguese scene for free improvised music, both as a collaborator and in leading his own groups including many important and creative musicians.
Has created the record label Creative Sources Recordings in 1999, which mainly concentrates on releasing experimental and electro-acoustic music.
