Biography

Zehao Dong

Hello! I am a PhD candidate in Physics at Tsinghua University, focusing on strongly correlated materials, particularly high-temperature superconductors. My previous research involved using scanning tunneling microscopy (STM) and tunneling spectroscopy to investigate their electronic properties. Currently, I am developing novel computational imaging techniques for scanning transmission electron microscopy (STEM) and applying them to visualize local structural defects in quantum materials.
