His list of compositions includes works for orchestra, chamber ensembles, choir, solo instruments (specially the piano), operas, as well as several electroacoustic works. He has been performing widely as a pianist, conductor, and sound-projectionist, often taking those tasks simultaneously, as in the case of his piano concerti with live electronics.

He currently teaches Composition, Theory, and Computer Music at the Universidade Estadual de Maringá (State University of Paraná at Maringá) in Brazil, where he created and also directs the Laboratório de Pesquisa e Produção Sonora - LAPPSO (Laboratory for Research and Audio Production).

His music possesses an experimental character marked by a varied pallete of musical sound materials and techniques, which reflects his interest and investigation in the domains of form, polyrhythm and simultaneities, timbre, sound spatial perspective, microtonality, and orchestration of sound objects. His works are published by Vultur gryphus publishing house and some of his discography is available through the Electric Music Collective label.
