Digital native and coming from a farming family, Mathieu is interested in the influence of technology on the perception of our contemporary reality. He questions the internet materiality and its representations. It seeks to translate the spiritual experience of the internet user, the imagination of the surfer facing this endless flow of information. He uses as medium the big datas. Through his algorithms that he develops, through recycling processes and analogies to nature, he shapes data flows in order to create tangible materializations. Abstractions, relics, crystallizations or fragment of the World Wide Web, his protean work materializes mainly in sculptures and multimedia installations.
