Skills

Research topics :
Studies of interactions between polymer plant cell walls
Development of biomimetic plant cell wall assemblies based on from cellulose nanocrystals, hemicelluloses and lignins and characterisation of their physico-chemical (spectroscopic, optical, hygroscopic, thermo-mechanical) and functional (antioxidant properties, etc.) properties.
Structure and Properties of biopolymers at interfaces (fluid, solid) - Applications: proteins, macromolecules of Champagne, lignins,…

Technical skills :
Langmuir-Blodgett, Spin-coating, casting
Spectroscopic ellipsometry; Ellipsometric microscopy; Surface Plasmon Resonance,  spectroscopies (UV/Visible/IR, fluorescence), Tensiometry (bubble, Wilhelmy plate, contact angle); Scattering light diffusion, Neutron Reflectivity;
Biochemical analyzis (HPLC, electrophoresis,…)

Research interests

Understanding at the molecular, nanometric and micrometric scales of i/ native or bioinspired polymer assemblies (cellulose, hemicelluloses, lignins), ii/ mechanisms leading to parietal cohesion and accessibility of lignocellulose walls by destructuring agents (hydrolases, oxidases, etc.): individualisation of the mechanisms involved through the use of bioinspired systems of increasing complexity, iii/ valorisation of lignocellulosic assemblies in higher added-value applications.

Current projects: EcoDROP (Carnot 3BCAR, 2023-2024), ANR LABEL (2023-2026), EUR PIA3 - NANOPHOT (2020-2024), NAFILAB (Ademe, 2023-2025).
