Philippe Deniard (DR)

Structural analysis: (RX and neutrons, powder and single crystals, non harmonicity of atomic displacement parameters, resonant scattering, super space group magnetic structure, development of fundamental parameters approach, PDF analysis).

Ab initio structural determination: (direct methods, parallel annealing, flipping charge)

Quantitative analysis: (with or without amorphous phase, by Rietveld or PDF).

Organization of powder DRX training for 23 years and additional training for 6 years.
