Short Biography

I am a CNRS Research Director at the Laboratoire de Chimie of ENS de Lyon. After graduating from Chimie ParisTech, I obtained a PhD in physical chemistry at CEA Saclay (2006) and held postdoctoral positions in Lyon, Grenoble and at ESPCI Paris. I joined CNRS in 2010 at the Laboratoire de Physique des Solides in Orsay, and moved to ENS de Lyon in 2016.

My research lies at the interface between soft matter physics and nanoscience. I study colloidal nanocrystals, in particular ultrathin semiconductor nanoplatelets: how they form, how their surface ligands control their curvature and chirality, and how they self-assemble. My work combines synthesis, in situ X-ray scattering and numerical simulations.
