Mathieu questions the internet materiality and its representations. In the manner of an alchemist, he creates his subjects which he shapes and transforms mainly in sculptures, installations, but also images, videos and performance. His preferred approach is close to engineering. He notably develops algorithms to recycle these masses of data accessible on the web. He recycles “data” of search engines and tries to create tangible materialization of the network. Coming from a family of farmers, Mathieu seeks to question our contemporary environment, our nature, and our beliefs toward technology.
