Nicolas obtained one of the CLIMACT starting grants for the project he is leading on “the unseen processes of enhanced weathering”. This project includes a collaboration with Lyesse Laouli (EPFL), Stéphanie Grand (UNIL), Pascal Schwaab (UNIL) and Marie Perga. In this one-year long project, Nicolas garnered biogeochemical competences from soils, terrestrial and aquatic environments to provide an exhaustive and comprehensive state-of-the-art of the current knowledge about EW approaches and to scrutinize the data and modelled processes on which assessments of EW efficiency are based.
