My research group develops advanced materials for next-generation nuclear technologies, such as spherical tokamak nuclear reactors. These reactors require high performance radiation shielding materials and high temperature structural materials to be developed.
The first part of my research is to improve our understanding of the degradation of such materials in extreme environments including thermal-mechanical stresses, corrosion, and irradiation damage. The second part of this is to use this understanding to optimise the processing and microstructure of these materials for enhanced performance. This research spans refractory metals, structural ceramics, and their associated composites.
I supervise 3 PhD students and 2-3 Masters-level projects per year. I work with industry in the nuclear energy and manufacturing sectors including Tokamak Energy, Plansee, SECO tools, Tosoh SMD and Hyperion M&T.
Materials degradation in extreme environments: (i) the mechanics of materials at high temperature; (ii) oxidation processes simulating reactor accident scenarios; and (iii) irradiation damage characterisation using micromechanics and microscopy.
Processing and microstructural optimisation: (i) metal-ceramic composites for damage tolerance; (ii) oxidation resistant coatings; and (iii) texture engineering and grain size control.
