I am a physical chemist working at the Chemistry Lab of the École Normale Supérieure de Lyon. My research lies at the interface between materials science, soft matter and nanotechnology.
My main current interest is ultrathin 2D colloidal nanoparticles: their synthesis, surface chemistry and conformation. I also study the self-assembly of nanocrystals from the perspective of the emergence of collective properties. This implies understanding colloidal forces between particles at the nanoscale. I am also interested in probing the formation mechanism of nanoparticles using in situ synchrotron-based X-ray techniques. I have expertise in Small Angle X-ray Scattering.
I have a PhD (2006) from École Polytechnique and i hold the "habilitation à diriger les recherches" since 2016.
