Research project
Main project: Enabling a new generation of advanced high-strength aluminium alloys through materials design.
This project will develop an analysis-engine of novel atom-sensitive methods to unlock the materials science of hierarchy-strengthening. This research will enable determination of how hierarchical structures evolve and synergistically strengthen a new generation of advanced high-strength Al alloys that are strong as steel, but a third the weight.

Other Research Interests
Phase transformations and nanometre scale structure to property relationships of materials, in particular metallic alloys. Enabling materials design through determination of property origins. Novel processing routes to affect nanostructured and hierarchical materials architectures. Advanced characterisation techniques.
