Thibault Demoulin, co-founder of Oxara, is a material scientist with a background from the University of Rennes in France and the Technical University of Munich in Germany. His passion for heritage preservation started during his master's thesis at the Archaeological Museum of Bavaria, where he explored methods to conserve wooden artifacts. At ETH, under the guidance of Prof. Flatt, he delved into the conservation of historic buildings, recognizing the potential of seemingly weak materials when used appropriately. Collaborating with Dr. Gnanli Landrou, they co-founded Oxara to develop Gnanli's cement-free earth concrete invention, securing Horizon Europe grants and Klimatstiftung awards for their work.
