CHENHANG XU
Postdoctoral Scholar, Physics
BioI am a postdoctoral researcher at Stanford University in the Zong/Hwang group. I received my undergraduate and doctoral degrees from Shanghai Jiao Tong University (SJTU), where I specialized in pulsed laser deposition, the synthesis of complex oxide materials and MeV ultrafast electron diffraction (UED).
My research focuses on ultrafast structural dynamics in quantum materials using techniques such as MeV-UED, ultrafast electron microscopy (UEM), time-resolved X-ray diffraction, and pump–probe optical spectroscopy. These time-resolved probes are integrated with advanced and highly tunable sample environments, including in situ strain engineering and electrostatic gating, to actively control competing electronic, structural, and ferroic orders. This capability enables the design, discovery, and quantitative understanding of nonequilibrium phases, transient orders, and metastable states in quantum materials. -

Zhefu Yu
Postdoctoral Scholar, Physics
Current Research and Scholarly InterestsMy research aims to understand how supermassive black holes (SMBHs) grow over cosmic time, one of the key questions in astrophysics.
I have done substantial work in accurately measuring the mass of SMBHs through reverberation mapping (RM). In particular, I derived a new relationship between the radius of the Mg II broad line region and the continuum luminosity of the active galactic nuclei (AGN) based on the OzDES RM project, which is critical for SMBH mass measurements and demographic studies in cosmic noon – the peak of AGN activity. I have also done extensive work in understanding the accretion physics in both AGN and quiescent SMBHs.
Now my work focuses on better understanding the accretion onto SMBHs, the major path of SMBH growth. I collaborate closely with the XOC group and the Rubin LSST team in KIPAC. My research probes the inner most region of the AGN accretion disk through joint analysis of the X-ray spectral and timing data. I will also probe the accretion disk through time domain analysis of the LSST data in the near future.
