🔬 Research Interests

  • Metal Additive Manufacturing: LPBF, rapid solidification, thermal cycling, and post-processing.
  • Physical Metallurgy: Phase transformations, microstructural evolution, crystallographic texture, and phase stability.
  • Materials Characterization: SEM/EDS, EBSD, TEM/STEM, XRD, and quantitative microstructural analysis.
  • Mechanical Behaviour: Strength, ductility, hardness, toughness, and deformation mechanisms.
  • Corrosion Science: Passivity, localized corrosion, electrochemical characterization, and microstructure–corrosion relationships.
