Strain and defects in materials

X-ray diffraction, numerical computing and deep learning

I am a Research Director at the French National Centre for Scientific Research (CNRS), in the Institute of Research for Ceramics (IRCER, UMR CNRS 7315) in Limoges. This is my personal professional homepage, hosted at the University of Limoges.

My research focuses on the nanostructure and the structural defects of materials, studied with X-ray diffraction, numerical computing and deep learning for advanced data analysis.
