Why is geology essential in the transition to a more sustainable future, and how can we do a better job at explaining the importance of geological knowledge to society? These are the main questions guiding my research.
During my PhD in University College Dublin (Ireland), I studied pegmatites as resources of lithium and other critical metals that are used in batteries and other clean energy technologies in development.
Since joining the Geological Survey of Belgium in 2019, I coordinated the GeoConnect³d project (finalised in 2021), investigating different subsurface uses related to geo-energy in order to develop an online tool displaying geological information for policy support and subsurface management in Europe. Currently, as part of the LIBS-SCReeN project, I am contributing to the optimisation and application of Laser-induced break-down Spectroscopy (LIBS) techniques for multiscale detection and characterisation of critical raw materials.
