Research

Research interests

Developing specialised techniques in scientific preparation of geological and synthetic materials
Application of scanning electron microscopy to:

  • Imaging
  • X-ray microanalysis
  • Electron backscatter diffraction (crystal orientation mapping)

Conventional and digital photography of features in rocks and minerals, also: image enhancement and processing to extract stereological informationLight microscopies and infra-red spectroscopyMineral processing, including: synthesis, separation, purification and controlled atmosphere firing of phases
