My primary research interests are:
- Radioactive Mossbauer Spectroscopy: 57Fe/119Sn Mossbauer investigations on a suite of oxides, semiconductors and III-V nitrides after implantation of 57Mn* /119In*. Mossbauer Spectroscopy is being adopted as an investigative tool to examine the defect and dopant diffusion in semiconductors such as Si, SiGe; magnetism in ZnO, MgO and Al2O3; annealing of implantation induced lattice damage in diamond, SiC, GaP, GaAs, InAs, GaN, InN and AlN.
- Transmission Mossbauer spectroscopy (Room Temperature and in-situ): 57Fe Mossbauer studies of perovskite systems for example doped BiFeO3 materials as a function of Fe concentration and temperature.
- Room Temperature Conversion Electron Mossbauer Spectroscopy (CEMS): Fe enriched films, single and polycrystalline materials.
My secondary research field is Physics Education which focuses on students learning experiences, their understanding of concepts and problem-solving skills.
