I am a soil biogeochemist working for the French National Research Center (CNRS) at the Institute of Ecology and Environment in Paris, France. My work is concerned with the dynamics of organic matter at the molecular scale and the biogeochemical cycling of carbon, nitrogen and phosphorus in natural and managed ecosystems.

During my 25 years lasting carrier, I studied the origin and fate of terrestrial organic matter in several environments, ranging from soils and sediments in coal mining areas to organic matter in natural as well as managed ecosystems, including those affected by fire. My work is dealing with temperate and tropical environments. I contributed to the change of several paradigms in my field. Since a few years I am interested in the development of innovative organic amendments and smart fertilisers. I supervised 17 PhD students to successful completion of their thesis and have published more than 180 papers in international peer reviewed journals. In 2016 and 2017 I was listed as a highly cited researchers in the field of agronomy. I am engaged in the international 4 per 1000 initiative as the chair of the scientific and technical committee.
