After having collaborated as an interpreter with Marcel Marceau, Philippe Genty and Jean Paul Goude, Lionel turned towards directing with numerous collaborations abroad in fields as diverse as theater, music, circus or dance.

The point common to all these meetings is that they make Lionel travel to all four corners of the earth. The piece of which he is most proud, however, was performed only once and did not depart its four walls – this was the directing of "La Volière" at the Fresnes Penitentiary Centre for long-term prisoners.
