Most significant contributions are in the field of thin film epitaxy- functional property relationships for ferroelectrics, dielectrics and multiferroic nanomaterials. Areas of research include thin-film oxide epitaxy, scanned probe microscopy of functional materials and Landau- Ginzburg modelling of phase-transitions. Recognition of this includes: 90+ papers in international journals; $6m research funding since 2005. Currently supervising 7 PhD; successfully supervised 6 PhD completions and 1 MSc since starting at UNSW.
Courses taught are in the areas of Diffusion and Kinetics, Advanced Nanomaterials, Introduction to Materials Design and Nanotechnology, Solid State Chemistry and Nanofabrication.
