Former Ph.D. student at the Paris Institute of NanoSciences in the picosecond acoustic team of Bernard Perrin under the supervision of Laurent Belliard.

I used Pump-probe spectroscopy to study thermal and acoustic confinement in nano-objects. In previous projects, I was involved in developing innovative photovoltaics processes and devices at IRDEP and Imperial College London.
