Key Research Interests

  • Fracture patterns, including their quantification in 2D & 3D using tensors, polymodal faulting.
  • Rock physics, including laboratory & core data analysis & modelling, velocity anisotropy, permeability anisotropy; clastics, carbonates, evaporites and basement (igneous & metamorphic).
  • Geomechanics, including fault & fracture stability, probability of failure (shear & tensile).
