As a physicist with a background in solid state chemistry, I am interested into how structure affects materials properties. Hence, I am focusing on magnetic behavior and magnetic structure of oxides, especially when they possess magnetic frustration and/or magneto-elastic coupling. In 2011, I started to explore insertion compounds such as oxides or polyanionic compounds for their alkaline insertion properties for Li-ion and Na-ion batteries materials. I am an expert at resolving structures from powder diffraction patterns (either by a direct method or by global optimization methods) and in refining their structure using the Rietveld method, as well as in neutron magnetic diffraction.
