Professional comic book artist. He also is still attending university, studying so he can be a teacher as a back up to comic books. He can speak French and Italian, and is also fluent in English. He has worked with Vertigo for about ten years now.

He first went around promoting Bone Rest at conventions so he could be discovered. Later the editors of Vertigo would utilize his talents, where he would be a fill in artist for Brian K. Vaughan's Swamp Thing (Also know as Swamp Thing Vol. 3). From there he would stay associated with Vertigo, working on Hellblazer with Brian Azzarello, Mike Carey, Andy Diggle, and now he is the regular penciler on Peter Milligan's run.

Because superheroes run the comic market, Giuseppe is mostly known for his work on Marvel. He enjoys darker characters, characters like Dark Wolverine (Daken) and John Constantine have become staples for him throughout the years.

He recently participated in a small run of Amazing Spider-Man, the return of Jean DeWolff, alongside Dan Slott, Klaus Janson and Matt Hollingsworth, pencilling Anti-Venom, Spider-Man and Wraith. In addition, he also contributed to the prelude to Schism four issue miniseries.
