Dr Reza Kashtiban

Biography

I am an experimental physicist and materials scientist with a specific interest in studying the structural and compositional properties of nanomaterials using advanced Transmission Electron Microscopy (TEM). From 2007 to 2010, I worked as a visiting researcher at the UK's mid-range electron microscopy facilities at Daresbury Lab (SuperSTEM), where I used the Electron Energy Loss Spectroscopy (EELS) technique to study semiconductor nanostructured materials. My current research focuses on the growth and engineering of properties, as well as the chemical characteristics, of encapsulated composite nanomaterials. I am also interested in studying 1D radial Van der Waals (VdW) heterostructures, 2D materials, as well as characterising beam-sensitive porous materials and functionalised carbon-based materials. I also specialise in phase restoration through Exit Wave Reconstruction (EWR), commonly known as inline holography.
