Research interests

  • Mechanical characterisation of particles: Measurement of hardness, Young's modulus, yield stress, fracture toughness, size, density and porosity
  • Size reduction: Breakage and attrition of the particles (during milling, impact, bulk compression, shear deformation and fluidisation) and study of its relationship with single particle properties
  • Compression behaviour of the bulk particles (in terms of deformation, compaction, crushing) and its relationship with single particle properties
  • Size enlargement: Granulation of powders, including wet granulation in high shear mixers, modelling and scale-up of high-shear granulators
  • Dispersion of powders: For the application of dry system size analysis, and dry powder inhaler
