I am a DPhil student working with Prof. Marina Filip in the Computational Condensed Matter Physics research group. My research interests involve applying density functional theory and Green's function based approaches for many-body perturbation theory (such as the GW and GW-BSE methods) to perform first-principles calculations of the optoelectronic properties of semiconductors, especially hybrid halide perovskite semiconductors.
I have particular interests in the coupling of excited electronic states of materials to lattice vibrations (so-called electron-phonon and exciton-phonon coupling) and developing techniques and tools to perform these calculations accurately and efficiently by studying convergence properties of first principles calculations.
I joined Prof. Marina Filip's group first for my MPhys research project, during which I worked on bringing the group's advances in understanding the effects of phonon screening on excitonic properties to a wider range of materials. I principally used density functional theory calculations with the Quantum ESPRESSO package, which I developed in-house tooling for, to calculate the electronic and vibrational properties needed to approximate the phonon-screened excitonic properties of a range of III-V and II-VI semiconductors. These materials continue to be valuable environments for testing the more advanced methods I work with now.
