Born in 1996 in Paris, Sidonie Ronfard is a photographer and visual artist, and a graduate of ENSAD (Photography & Video department). In 2019, she was awarded the Prix de la Jeune Photographie Européenne and exhibited her work in Paris alongside the other laureates. That same year, she joined the Master of Photography program at Aalto University in Finland.

In 2022, Sidonie took part in an artist residency aboard the vessel Marion Dufresne in collaboration with IFREMER, marking her first exploration into the convergence of art and science.

In 2023, she was a finalist for the Prix AMMA (Contemporary Art Prize), an achievement marked by the exhibition of her work “Emotional Overlap II” at the Bastille Design Center in Paris.

In 2024, she presented her first solo show, "Turbulences", at the Chapelle des Carmélites in Toulouse. This exhibition was the culmination of the Résidence 1+2 Factory #14 x CIMI residency, where she addressed the theme of "Uncertainty." The CIMI (Centre International de Mathématiques et d'Informatique) is a prestigious "Laboratoire d'Excellence" (LabEx) supported by the ANR. It brings together researchers from the IMT, the IRIT, and the LAAS-CNRS to foster innovation in mathematics and computer science. Her research was also the subject of a public talk at the Musée des Abattoirsduring the "Photographie & Sciences" colloquium, held alongside the four laureates of the 2024 Résidence 1+2.

Her work is deeply rooted in self-publishing, which she utilizes as a tactile and narrative extension of her photography. Her expertise in the field led her to become a 2026 finalist for the BOLD photobook prize, awarded by the Fondation Henri Cartier-Bresson.

Her work focuses on creating universal "states of soul" (états d’âme) through textures, sensations, and intuition. She explores the ongoing dialogue between human perception and that which escapes our grasp.
