META TEAM

I am a member of the team « Meta-atoms, metamaterials, metasurfaces » at the CRPP. We are interested in the design, fabrication and study of self-assembled metasurfaces and metamaterials, both for acoustic and optical waves.

RESEARCH INTERESTS

Colloidal nanostructures, applications to metamaterials and metasurfaces / Self-assembled colloids and polymer systems / Light scattering by colloids and porous materials / Functional nanocomposites based on organized block copolymers/ Structured complex fluids and surfactants self-assembly / Soft nanocomposites
