For volume 2, he was awarded the Coup de Cœur prize at the Chambéry Festival in 2001.

One year later, the first volume of a long collaboration with Crisse was published: Kookaburra Universe, which tells the story of the origins of the charismatic Dragan Preko, hero of the successful science fiction series Kookaburra, whose drawing Crisse entrusted to him in 2004. In 2006, he became the collection director of this space-opera in 27 volumes, divided into three series, and in 2007, he scripted Kookaburra K, in collaboration with Humberto Ramos and co-edited by Marvel in the United States.

The first of them was nominated for the 9/12 years old prize at the 2005 Angoulême International Festival and received the prize of the Maison Laffitte Festival.
In 2010 he signed Seven Dragons with Delcourt, drawn by Sylvain Guinebaud and in 2012 at Glénat, the book Ultime voyage en Alchimie, prize of the Creil book festival.
