Julien Solé is a regular contributor to the magazine Fluide Glacial, using strange pseudonyms like Julien CDM, Julien/CDM and Ju/CDM.

From 1995, he started working as an artist of infographics for the pioneering website of Fluide Glacial, together with his brother Vincent (Vincent/CDM). The brothers have continued to manage the magazine's site, including the webzine @Fluidz, for many years. By 1997, he published his first short stories scripted by Manu Larcenet in the print magazine. These stories are collected in the album 'A L'Ouest de l'Infini' (1999). In 2000, he began the futuristic series 'Cosmik Roger', that is written by Mo/CDM and published in book format since 2002. He additionally created 'The Zumbies' with Yan Lindingre, of which a book was published in 2010.
