Summary of research activities and skills

My research activity aims at valuing the marine algal biomass (including aqueous phase and bioassimilable minerals) by the means of authentic technologies (i.e membrane filtration, eco-extraction) through a biorefinery process with applications in cosmetics and health.

On the other hand, an upstream research on the syntropic role of water is continued. Specific waters (algal cellular water, seawater, dynamized water) are used to study the interfacial water and the effects of non-chemical treatments such as electromagnetic fields, resonance frequencies, nanobubbles, marine limestones, etc. A global approach based on information physics and quantum electrodynamics is an original way to propose models explaining the phenomena observed, for example in the case of high dilutions.
