Background and activities
Current Work
My current work is centred around understanding the role of ionic diffusion in solid electrolytes for battery applications, together with the prediction and characterisation of new materials using density functional theory (DFT). In addition to this, my interests span across a range of functional materials including transparent conductors, thermoelectrics, photovoltaics and photocatalysis for water splitting and carbon dioxide reduction.

Background and Previous Work
My work has centred around the bulk electronic and defect properties in semiconductors for a range of applications including: n and p-type transparent conductors, photocatalysis, photovoltaics and thermoelectrics. My work has involved the use of computational simulations to further the understanding that the role of defects and dopants play with respect to the electronic structure as well as using predictive tools to find the next generation of functional materials.
