• Exploring emerging physics such as ferroelectricity, ferroelasticity, and phase switching in novel 2D materials down to monolayer thickness: • Understanding reaction mechanism on nanocatalyst surfaces, through capturing reaction dynamics using various in situ and ex situ characterization techniques including liquid and gas TEM holders

• Developing ultralow-dose TEM techniques to unravel the structure information in beam sensitive materials including hybrid perovskites, polymers, MOFs, and battery materials

• Developing novel 4D-STEM techniques to reveal the intrinsic electric and magnetic fields in functional materials at nanometer or even atomic scale


• Spatially-resolved spectroscopy to map chemical composition, electronic structure, and surface plasmonic resonance.
