My research activity is concerned with the study of silicate and alumino-silicate glass structure by combining various spectroscopic methods (Mössbauer spectroscopy, X-ray absorption spectroscopy, Optical absorption spectroscopy, Nuclear magnetic resonance spectroscopy...) with calculation or modelisation tools (Molecular dynamics simulation, ab initio calculation...) well adapted to the "disordered" nature of glasses .

Bioweathering of glasses of geological and historical interest

Recently, I started working on the bioalteration of silicate glasses of geological (primitive glass compositions containing Mg) and historical (medieval stained glass-windows) glasses. My principal interest is to describe elementary mechanisms combining knowledge on (i) the structure of the glasses before alteration, (ii) the water chemistry of the alteration solution and (iii) the nature of the alteration phases.
