I am Haoyang Ni, a graduate student at University of Illinois, Urbana-Champaign (UIUC) and research intern at Oak Ridge National Laboratory. My research focuses on using multi-modal scanning transmission electron microscopy, diffraction and spectroscopy to understand strongly correlated quantum phenomena. The key information I am looking into is to probe the local structures and heterogenieties of materials and their impact on quantum state. In the meantime, I deal with large datasets by developing physics-informed analytical methods.
