Researcher in physics of laser-matter interaction since 2003, I specialized in carrying out X-ary spectroscopy experiments, for which I was led to design different types of spectrometer. The experiments, in which I participate, are carried out on various laser installations, ranging from ultrashort pulses at high repetition rate and moderate energy, to very high energy lasers such as the MegaJoule Laser. I am currently studying the solid-plasma phase transitions occurring in the particular regime of the warm dense matter; where the matter is close to the solid density and at temperatures around ten thousand Kelvin. It is on this theme that I supervise university interns and students preparing a doctoral thesis.
