Research interests

My work focuses on the multiscale modelling of charged systems and their applications to systems of industrial and environmental interests in the field of Energy. More specifically, I am interested in charged porous materials such as clays for their role in the geological disposal of nuclear waste and in CO₂ sequestration, as well as nanoporous carbons for electricity storage in supercapacitors or for the harversing of blue energy (exploiting salinity gradients between sea- and river water) or desalinition.

The aim is on the one hand to understand the mechanisms reflecting chemical specificity on the molecular scale, and on the other hand to introduce appropriately their effects on larger scale models, where other the structural complexity of materials has an impact on transport properties. Therefore I work not only on the simulation at the molecular and mesoscopic levels, but also on the link between the various levels of descriptions. This also involves methodological developments on the various scales.
