My research field is computational physics applied to materials engineering, fluid mechanics, oceanography and integrated modeling of natural and anthropogenic effects. The basic objective is the development of mathematical models and numerical tools for predicting the behaviour of complex systems. I also started a research work in unstructured-mesh numerical oceanography. Though ocean modelling made huge progress since Bryan's pioneering work, the basic aspects of most models have remained similar to those of Bryan's: finite difference techniques are still implemented on structured grids. Unstructured mesh offer much more flexibility than structured ones. Since it is most probably impossible to modify step by step a structured-grid model to obtain an unstructured-grid one, a revolution -- rather than an evolution -- is needed in ocean model design, paving the way for the second generation of ocean models.

Immersed granular flows are daily used in many industrial processes. Avalanches, lava flows and transport of marine sediments involve fluid-grains mixtures. The great inhomogeneity that can be encountered in immersed granular flows and the influence of these inhomogeneities are mainly responsible to the lack of knowledge. Developing a fast asoftware to compute immersed granular flows can improve processes in pharmaceutical, cosmetic, chemical and agro-food industries as well as to understand many natural phenomena.
