Research Interests

  • Electron backscatter diffraction (EBSD) applied to microstructural, strain and texture measurements
  • Strain and stress determination using cross-correlation based EBSD technique for the development of nanoscale strain standards
  • High resolution X-ray diffraction using lattice comparator with 10-8 accuracy for lattice spacing and strain standards development
  • X-ray diffraction applied to texture and stress measurements using area and linear detector-based diffractometers
  • Scanning electron microscopy applied to broad spectrum of materials
