Born in Adelaide to Hungarian and Dutch parents, Jules obtained a Bachelor degree in Music Performance (Viola) and as a young man made his conducting debut at the Adelaide Town Hall.

Other performances include the Melbourne premier performance of Natalie Williams' Chambers of the South, Mozart’s Piano Concerto no. 27, Stravinsky’s Firebird Suite and Schumann’s Piano Concerto.

Jules has also studied with conductors Nicholas Braithwaite, Carl Crossin, Shalom Ronly-Riklis, Carlo Felice Cillario, Denis Vaughan and Graham Abbott. As an instrumentalist, he has led the viola section for Melbourne Opera Company for two years.
