研究领域

My research centres on the applications and development of high-resolution electron microscope techniques, in particular scanning transmission electron microscopy (STEM), including atomic resolution Z-contrast imaging, electron energy-loss spectroscopy and applications of spherical aberration correctors. Our technique development work includes methods for the three-dimensional imaging and spectroscopy of materials, and methods to allow high resolution imaging and spectroscopy of radiation sensitive materials. Always we aim to use microscopy data in a quantitative way to make measurements of the atomic and electronic structure of materials.
