Xianhu Sun is a professor at the University of Chinese Academy of Sciences. His research focuses on advanced materials and surface/interface science, particularly using in situ transmission electron microscopy (TEM) to study dynamic structural evolution, redox processes, and catalytic mechanisms in nanomaterials. He leads an ETEM (environmental TEM) research group and has contributed to understanding surface–bulk interactions and defect dynamics in functional materials.
