Research axes :
- Catchment and hillslope hydrology
- Numerical modelling of water and solute transfers in hydrosystems

Current research activities :

The overall objective of my current research is to improve the current understanding of runoff generation processes and of the response of hydro-systems through the development and the application of reliable modelling tools.

I am currently involved in :

- the development of physically-based distributed hydrological models that can describe in a physical way the interactions between surface and subsurface processes and the coupling between flow and transport

- their application on synthetic test cases to assess (i) the relevance of both the physics and the numerics used for the description of the coupled processes, and (ii) theoretical aspects linked to runoff generation and hydrograph separation

- their application at the catchment scale to study runoff generation processes, saturated areas dynamics, and hydrograph separation issues.
