I am a postdoctoral researcher working with Julie Staunton, using computational modelling to study the magnetic properties of materials.
Prior to working at Warwick, I completed my doctorate under the supervision of Feliciano Giustino in the Department of Materials at the University of Oxford. I then spent two years at the Technical University of Denmark (DTU) working with Kristian Thygesen in the Centre for Atomic Scale Materials Design (CAMd).
About my research
The underlying goal of my work is to understand the behaviour of materials in terms of the individual electrons and nuclei which they are made of. At Warwick I am working as part of the PRETAMAG project, investigating the Physics underlying the principles of Rare Earth TrAnsition-metal permanent MAGnets. This particular topic nicely incorporates a number of research themes that I am interested in:
- Using calculations to interpret experimental data: e.g. why a magnet's preferred direction of magnetization changes with temperature, understanding X-ray measurements of water and the electron microscopy of dye molecules on titanium dioxide
- Understanding how the motion of nuclei affects the behaviour of electrons: e.g. how a material changes shape when a magnetic field is applied; how the optical properties of nanodiamond are affected by the quantum fuzziness of the carbon nuclei; why some crystal phases of cesium tin iodide (CsSnI3) are stable only at high temperature
- Improving the accuracy of calculations: e.g. applying techniques developed for idealised systems to calculate the properties of real materials; investigating theoretically "tricky" materials like the lanthanide elements
- Simulating phenomena across different length scales: e.g. using quantum mechanical calculations to calculate parameters which can be fed into larger scale micromagnetic simulations
