Biography

Laurent De Windt is a researcher specializing in the study of geochemical interactions and reactive transport processes as they apply to environmental and industrial contexts, particularly in the fields of radioactive waste management and the remediation of contaminated sites. His work focuses on modeling the degradation mechanisms of materials, such as cements and steels, under extreme conditions (high temperatures, oxidizing or reducing environments, and the presence of metallic contaminants). He also explores sorption and mineral precipitation phenomena to assess the mobility of radionuclides or heavy metals in aquifers and soils, integrating experimental and numerical approaches. His expertise includes the analysis of multiphase systems (water-gas-rock) and the impact of geochemical disturbances on the durability of engineered or natural barriers, thereby contributing to the optimization of storage or remediation strategies.
