He started taking piano lessons two years later. It was in highschool where he discovered his love for jazz and improvised music.
After High School he studied at the Hochschule Luzern - Musik Jazz Departement.
His teachers and mentors included Pierre Favre, Gerry Hemingway, Norbert Pfammatter, Lauren Newton, Christoph Baumann, Ed Partyka, Roberto Domeniconi, Hans Feigenwinter and others.

The Collaboration in the quartet of outstanding harpist Julie Campiche woke his interest in electronics and ecouraged him to extend his musical research in that field.
