Trained at the École nationale supérieure des Arts Décoratifs, Bertrand de Miollis makes travel the foundation of his work. Since 2002, his expeditions—a tour of Africa, the Trans-Chilean route, Paris–Kabul, Lake Baikal—have nurtured a sensitive perspective on the world. In Afghanistan and Iraq, he accompanied French and British troops; his travel journals were published in the press and by various publishers.

He also develops the "immobile journey" through artistic immersions: polo, opera with John Eliot Gardiner, residency within the Paris Opera.

Watercolor, oil, engraving, and then digital media: his research, fueled by motif, lies between abstraction and figuration. A confident colorist, he explores a vibrant tension between softness and chromatic intensity.
