Short presentation
Structural geology is my main research area, where I combine surface and subsurface data with analogue and numerical models to understand geological processes and structures. I work with modelling of rock-deforming processes in the crust and mantle lithosphere. My research has direct application to hydrocarbon and mineral exploration, groundwater accumulation and aquifer deformation, geological waste disposals, landslides and slope stability, and understanding earthquakes in mountian ranges.
