Présentation

Scientific interests

In general, I am mostly interested in the study of elementary excitations and particles (electrons, magnons, phonons, photons, plasmons, etc.), their interactions and their role in the onset of collective and macroscopic states that underpin the observed phenomena.

My present focus is on electrodynamics of hybrid nanostructures and the study of efficient channels for energy absorption, conversion and transfer.
