I have developed my interest in weathering since my MSc thesis on hydrothermally altered materials involved in debris avalanche at Casita volcano, Nicaragua. I completed my PhD in 2008 at the Faculty of Bioscience engineering of the Université catholique de Louvain (Belgium) on “Silicon cycle in the soil-plant system: Biogeochemical tracing using Si isotopes”.
In 2009-2010, I moved to the University of Oxford (UK) where I worked as a Post-doctoral Researcher in the Department of Earth Sciences.
Since 2011, I have been at the Earth and Life Institute of the Université catholique de Louvain (Belgium), where I was promoted permanent FNRS Research Associate in 2014. In 2014, I was presented with the Ebelmen Award of the International Association of Geochemistry in recognition for my contribution to the use of silicon isotopes to distinguish biological and inorganic processes.

Since 2016, I am teaching “Introduction to Earth Sciences” (LBIR1130) with P. Delmelle to first year students from the “Faculté des bioingénieurs” and “Faculté des sciences” (~500 students). The course is based on the book “Terre, portrait d'une planète” by S. Marshak. My contribution to this course is about mineralogy, the rock cycle, shaping the Earth surface, deformation and metamorphic rocks, fossils and evolution, geological times, Earth’s biography, Earth resources, processes and problems at the Earth’s surface (glaciers, deserts, global change). The practicals of this course represent the first opportunity for the students to manipulate minerals, rocks and fossils, get a direct sense of their properties, and discover their beauty under the microscope.

Nom ID Introduction aux sciences de la terre LBIR1130
The motivation of my research is the understanding of the Earth’s surface processes controlling chemical weathering and element export from continent to the hydrosphere (rock-soil-plant-water systems). Chemical weathering of minerals in the Earth’s Critical Zone is the engine that replenishes the soil mineral nutrient reserve and ultimately nourishes terrestrial and aquatic ecosystems. Changing weathering dynamics in the Critical Zone in response to climate and land use changes is expected to impact on mineral nutrient cycling and mineral nutrient export to rivers. With my research group, I tackle the complexity of interacting processes (abiotic, biotic) involved in mineral weathering by an analytical approach combining soil science, geology, geochemistry and isotope geochemistry (e.g., Ge/Si ratio, stable isotopes of Si, Mg, etc.).
