research focuses on the study of the thermodynamic behavior and physical properties
of complex mixtures such as polymeric systems and electrolyte solutions, by using
both equations of state and molecular simulation. Thermodynamics is essential
to chemical engineering, and is particularly important in the design and optimisation
of chemical processes. The study of phase equilibria is crucial for the design
of multiphasic reactors and separation processes such distillation columns. Some
applications of thermodynamics are the depollution of water, the extraction of
a compound by supercritical fluid or the study of the stability of a colloidal
simulation and theories developped from statistical mechanics have become very
useful tools to predict physical macroscopic properties (resistance, viscosity,
density, surface tension, solubilities and phase equilibria ...) from the knowledge
of microscopic properties (intermolecular potentials). They are particularly useful
when an experimental study would be difficult or impossible, and they enable to
understand complex behaviors at the molecular scale. Molecular simulation is more
and more used in the development of nanotechnologies, as it allows for the determination
of the physical properties of synthetized molecules which cannot be found in nature.

Here are my main research activities:
of vapor-liquid and liquid-liquid phase equilibria in polymer+solvent systems.
Development of a model to predict the solubility of gases in semi-crystalline
polymer, taking elastic effects into account.
In the design
of a gas phase polymerization process, it is necessary to know the solubility
of the monomers in the polymer grains, as this solubility directly determines
the rate of the polymerization reaction and the remaining quantity of gas after
the reaction. We have developped a model predicting the solubility of gas in polyethylene,
based the SAFT equation and the statistical mechanics of chain elsaticity, which
takes the plasticizing effects (due to the crystallites) into account.
of organic compounds in water/alcohol mixtures.
We are developing
a group contribution method based on thermodynamic models (SAFT, ...) to predict
the solubility of organic compounds in these mixtures. There are three main applications:
food, pharmaceutical and environemental industries.
phase equilibria in polymer+colloid mixtures.
of the polydispersity of chain length and colloid diameter.
simulation of aqueous solutions.
of polarizable force field for water and polar compounds.
