Current Research Interests

I am interested in the electronic properties of strongly correlated electron systems. Typically, these materials will have some degree of two-dimensionality, and exhibit phenomena such as spin density waves and unconventional superconductivity. The understanding of these materials requires a detailed knowledge of the experimental electronic structure, for which high-resolution Angle Resolved Photoemission Spectroscopy (ARPES) measurements are often indispensable.

My research at Diamond mostly involves investigating the electronic structures of materials which exhibit novel phenomena using the powerful technique of ARPES at beamline I05. I also compare the data with calculated electronic structures using density functional theory to try to come to a satisfactory understanding of the experimental observations. Recently, I have been studying FeSe, an iron-based superconductor with intriguing properties including a structural transition at 90 K, which we found to be associated with the onset of an orbital polarisation in measurements at I05.

My role at Diamond is mainly to design, perform and analyse high resolution studies at I05, but I am also interested in sample characterisation measurements and occasionally synchrotron-based measurements using other techniques.

Biography

I completed my undergraduate studies at the University of Oxford in 2011. I remained in Oxford for my DPhil studies at the Clarendon Laboratory, where my research focused on experimental determinations of electronic structures of iron-based superconductors, supervised by Dr. Amalia Coldea, graduating in 2015. During my doctorate, I mainly performed measurements in high magnetic fields in our home laboratory and at facilities abroad, using the technique of quantum oscillations to access the Fermi surface of materials. However, towards the end of my studies I became involved with ARPES studies, which are now the focus of my research. Following graduation, I remained in Oxford for a short postdoc before being employed as a Postdoctoral Research Assistant at Diamond since August 2015.
