Dr. Jérémie Margueritat — Nanoparticle Low Frequency Vibration


Jérémie Margueritat

I am a reasearcher at the CNRS. Since September 2011, I have worked at the Institut Lumière Matière (iLM), most recently in the Luminescence team. I use inelastic light scattering spectroscopies (Brillouin, Raman and low-frequency Raman) to study the mechanical properties of matter: from nanoparticles to biological cells. My current research topics include acoustic hybridization between nanoparticles, the detection of environmental changes through the acoustic vibration modes of nanoparticles, and the mechanical behavior of cancer tumors.
