1. RESEARCH ===========

I study how the fine-scale structure of geomaterials drives their macroscopic behaviour and failure. My approach combines full-field measurements at the mesoscale, mainly in-situ X-ray tomography and digital volume correlation, with numerical simulations that explicitly represent the microstructure: enriched finite elements (E-FEM) and random field models of the morphology.

After a decade on cementitious materials and the durability of concrete structures, my work now focuses on raw earth, a building material with a low environmental footprint. Many scientific obstacles are shared by both materials, and the tools developed for one remain relevant for the other.
