Increasing mesh resolution remains a key point in the improvement of the realism of numerical simulations. I am working on numerical schemes for integration of mesh refinement features in realistic numerical models.

Data assimilation is a powerful technique to couple model and observations according to error statistics. This powerful technique is accompagnied with a high computational cost that can be tried to be lowered using multigrid methods.

Developping numerical schemes is a special challenge that has to take into account the underlying physical properties : geostrophic balance, hydrostatic behavior
