Born in Plaisir where his studio is still based, Champy studied pottery at École des Métiers d'Art in Paris. His woodfired works are highly organic, often to the point of being sculptural, although most are fully functional vessels of some form. He describes himself as "a potter, not a sculptor. I shape the clay around a hollow which is a totally different approach."
The dynamic asymmetry of his pots display a looseness that typifies the predominant French stylistic approach to ceramic art. With works in many public and private collections throughout the world, Champy has received numerous awards for his work.
