About
Current Work
My current work involves using quantum mechanical simulations methods, such as density functional theory (DFT), ab initio molecular dynamics (MD), and self-consistent quasiparticle GW theory to characterise and predict functional materials.
My main focus is towards elucidating the ferroelectric properties of tetragonal tungsten bronzes within the HT2B project within the FACET group at the Department of Materials Science and Engineering at NTNU. Other projects within the group include understanding the role of ionic diffusion in solid electrolytes for battery applications, as well as the discovery of novel materials.
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.

PhD and Previous Work
Supervisor: Prof. David O. Scanlon, University College London
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.
