Summary of Expertise

  • (S)TEM Electron Microscopy characterization, development and management
  • EDX, EELS Spectroscopy
  • In-situ heating, Gas environment and electrical biasing characterization
  • Crystallography, defect structure analysis
  • Nanomaterials and nano-interfaces



My research is focussed on the understanding of the microstructure of nanomaterials and thin films down to the atomic scale. By using state-of-the-art conventional and aberration corrected electron microscopy techniques I aim to correlate the structural properties of materials, as such as crystallography, chemistry, defect density and epitaxy, with their macroscopic properties. In addition, I am interested in phase transformations at the nanoscale of materials as a function of temperature and gas pressure in reducing and oxidising gas environments.
