Assigned to the Research Department since 2021, William works on experimental and bibliographical research aimed at improving knowledge of the behaviour and fate of substances spilled in surface waters. He is studying innovative ways to better detect and mitigate the impact of pollution, particularly by chemical products. He actively participates in technological monitoring in his field of expertise and promotes his knowledge at national and international conferences. As a first-line duty officer, he also provided technical assistance following the rupture of a diesel pipeline, a flooding episode, the grounding of the Grande America, the fire at the Normandie Logistique/Lubrizol plant and the grounding of the Wakashio.
Before joining the Research Department, William was part of the Studies and Training Department since 2014 where he used his teaching skills or training courses for French authorities and administrations or private operators; he also wrote environmental emergency plans.
With a university education in physico-chemical process engineering and analytical chemistry, his scientific research profile was completed by a PhD thesis on the physico-chemical study of the wood-wine interface during barrel weathering for a cooperage holding company. His experience in instrumental development, especially valorised by a patent application, was completed by an experience as a research engineer at the French Scientific Research Centre (CNRS) to contribute to the development of an electrochemical sensor for the in-situ detection of nutrients. He also had an experience at the CEA in Grenoble on the development of chemical sensors for water analysis.
