In 2018, I graduated from the University of Nottingham with a MSci in Chemistry and Molecular Physics. Since then, I have joined the University of Warwick to study for my PhD in condensed matter physics. My PhD is titled "Probing the electronic structure of 2D heterostructures", supervised by Dr Neil Wilson.
My current research focuses on spatially-resolved angle-resolved photoemission spectroscopy (nano-ARPES) using synchrotron radiation, specifically at I05 beamline, Diamond Light Source (UK) and the Spectromicroscopy beamline, Elettra Sincrotrone Trieste (Italy). I study a variety of 2D materials and their heterostructures, including graphene, transition metal dichalcogenides (TMD) and post-transition metal chalcogenides (PTMC). In particular, twist dependant effects such as interlayer umklapp scattering and moirè superlattices.
