Kort presentation
Structural geology is my main research field. I combine surface and subsurface data with analogue and numerical models to sudy geoloigcal processes and structures in the crust and mantle lithosphere. My research has direct application to hydrocarbon (Energy) and mineral exploration (Natural resources), groundwater accumulation and aquifer deformation, geological waste disposals (Environment) , landslides and slope stability (Hazard), and understanding earthquakes in mountian belts (Hazard).

Forskning
Structural geology is my main research field. I combine surface and subsurface data with analogue and numerical models to sudy geoloigcal processes and structures in the crust and mantle lithosphere. My research has direct application to hydrocarbon (Energy) and mineral exploration (Natural resources), groundwater accumulation and aquifer deformation, geological waste disposals (Environment) , landslides and slope stability (Hazard), and understanding earthquakes in mountian belts (Hazard). Currently, I am working on the following projects:
1. Fault interference patterns in sedimentary basins.
2. Inversion tectonics.
3. Basement cover interaction in fold and thrust belts.
4. Kinematic evolution of deepwater fold-and-thrust belts: "gravity-driven" vs. "tectonic-driven".
5. South China Sea extension tectonics
6. Internal deformation of landslides.
