My research focusses on understanding the electronic, magnetic, and chemical properties at the surface of advanced nanomaterials in order to engineer them for a variety of applications. At the nanoscale, surfaces and interfaces play a critical role in how a device or sensor operates and a material’s surface properties often differ drastically to the bulk. Using a range of experimental techniques, my group aims to obtain a detailed fundamental understanding of nanoscale surface phenomena including molecular adsorption, surface reconstruction and relaxation, oxidation and surface magnetism. In addition to standard surface analysis tools such as photoelectron spectroscopy, low energy electron diffraction and scanning tunnelling microscopy, I have developed a unique instrument for performing spin-polarised metastable helium spectroscopy. Materials systems of particular interest include those relevant to spintronics and organic spintronics, and my group also investigates the surface properties of native and core-shell metal and metal oxide nanoparticles for biomedical and environmental applications.
