Scientific interests

  • Ice mechanical behavior, multi-scale approach, from dislocation to polycrystal
    • Characterization of deformation heterogeneities. Strain field measurements by Digital Image Correlation, lattice distortion via EBSD analyses.
    • Recrystallization mechanisms, dynamic and post-dynamic
    • Micro-Macro full-field modeling based on a Fast Fourier Approach.
  • Snow and firn microstructures and mechanical behavior.
  • Measurements and modeling of texture evolution along deep ice cores.
  • Formation and behavior of waterfall ice. Research project funded by the Petzl Foundation
