PhD, MPhys (Hons)
Senior Research Fellow
My research focuses on the study of structural and compositional properties of nanomaterials by means of advanced Transmission Electron Microscopy (TEM) and Scanning Transmission Electron Microscopy (STEM). I have extensive experience in analysing compositional properties of nanostructured materials through Electron Energy Loss Spectroscopy (EELS) technique both in Plasmon and core loss regimes. I also specialise in phase restoration by Exit Wave Reconstruction of Focal Series. My current research involves structural and compositional characterisation of nanostrucured carbon based materials, carbon nanotubes, nanowires, porous materials, graphene, functionalised graphene and other 2D materials, complex oxides, metal organic frameworks (MOFS), phase change memory devices and thermoelectric materials using various advanced aberration corrected electron microscopy techniques.
I have been working as forefront electron microscopist within a number EPSRC funded programme grants.

I have collaborated with several research groups, worldwide: For Er-doped Si nanocrystals structure Dr Andy Knight, McMaster University (Canada), Dr Russell Gwilliam University of Surrey, Prof. Matthew Halsall the University of Manchester. In the study of InAs/GaAs quantum dots Prof. Mohamed Missous, the University of Manchester and SuperSTEM team. For the gallium nitride-based materials Prof. David Mowbray the University of Sheffield and Dr Anabela Rolo University of Minho in Portugal for the Ge and SiGe nanocrystals in alumina and silica systems.
Teaching in Midland Physics Alliance Graduate School (MPAGS). I also teach part of the physics “Introduction to Microscopy” course.
