My research interests focus on the development and application of quantitative transmission electron microscopy techniques, including high resolution transmission electron microscopy, scanning transmission electron microscopy, quantitative electron diffraction, electron energy loss spectroscopy and 4D-STEM to solve materials problems in nanomaterials, thermoelectric materials, superconductors and electrode materials in Li-battery. I have also developed many computer programs for image processing, structure modeling, image simulation, dynamical electron diffraction calculations and refinements.
