I am a physical chemist working at the Chemistry Lab of the Ecole Normale Superieure de Lyon. My research lies at the interface between materials science, soft-matter and nanotechnology. I study the self-assembly of nanocrystals in 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.
