is a curator, researcher and photographer from France.

Currently based in Paris, Valentin previously worked at OMA/AMO with Rem Koolhaas where he participated in Countryside, the future, a research and exhibition project in Guggenheim New York. In 2025, he was the co-curator of the Luxembourg pavilion entitled Sonic Investigations at the Venice Architecture Biennale.

Valentin’s work ranges from installations, exhibitions, writing, film and photography, in which he focuses on ordinary encounters that manifest the entanglement of anthropogenic activities within our environment. His series look at specific territories, from urban to rural and in between, and explore our relationship to otherness through technology, socioeconomics and human intervention.

Valentin took part in the Experimentation in Arts and Politics program led by Frédérique Aït-Touati and Bruno Latour at the Paris Institute of Political Studies (Sciences Po). He taught a two-year research endeavor named Domesticated Foodscapes at the Swiss Federal Institute of Technology in Lausanne (EPFL) and participated in the program Organismo: Art in Applied Critical Ecologies facilitated by TBA21, a contemporary art foundation in Madrid.

Valentin has collaborated with institutions like Guggenheim New York, Brussels Center for Fine Arts (Bozar), French Academy in Rome (Villa Medici), Kunstverein Bielefeld and Archizoom, among others. His work has been published in books and magazines such as Spector books, Accattone, Cosa Mentale, Cthulhu books, DISC journal, Walkscapes, Trans, Parklife, CAHIER d’images and Yale Paprika. Convinced of the importance of transdisciplinarity to face the complexity of specific situations, he regularly collaborates with practitioners from varied disciplines: scientists, artists, thinkers, curators, designers, engineers, activists, programmers, and more.

In 2022, he co-founded MATTERS.xyz together with Alice Loumeau, a tentacular collective endeavor that explores new territorial narratives through creative research and exhibitions.
