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. -
Maya Emily Xu
Bachelor of Science, Honors, Biology with Honors
Masters Student in Biology, admitted Autumn 2022
Minor, Education
Stanford Student Employee, BiologyBioI'm an undergraduate ('25) and coterminal masters student majoring in biology (concentrating in ecology, evolution and environment). I previously completed a minor in education, a Notation for Science Communication, and will co-instruct BIO 121/221 (Ornithology) for the third time this spring.
Broadly, I'm interested in three main topics (which all have to do with birds!): 1) how birds can be used as indicator or sentinel species for environmental disturbance; 2) how interactions between humans and birds are shifting thanks to gradients of anthropogenic change; and 3) how these interactions can be shaped to better promote wider ecological health and beneficial services. I'm currently in the middle of a year-long study with Marty Freeland, funded by Jasper Ridge Biological Preserve's ('Ootchamin 'Ooyakma) (JROO) Mellon Grant, to compare the riparian bird communities at JROO and TomKat Ranch using three different survey methodologies (in-person transects, passive acoustic monitoring, and mob tape deployments). I'm also working closely with the San Francisco Bay Bird Observatory (SFBBO), where I volunteer as a bird banding trainee, and the Stanford SIGMA lab to quantify heavy metal contamination in the feathers of songbirds caught at the bird banding stations in JROO and the SFBBO's main station in Milpitas.
I previously conducted my senior honors thesis on how heavy metals affect raptors on the North American Pacific coast. My primary study species were the peregrine falcons (Falco peregrinus) breeding on top of Stanford University’s Hoover Tower, and the golden eagles (Aquila chrysaetos) breeding at JROO, where I'm a docent and former avian transect leader. -

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. -

Current Research and Scholarly InterestsMy research group is exploring a variety of topics that range from the basic understanding of chemical reaction dynamics to the nature of the chemical contents of single cells.
Under thermal conditions nature seems to hide the details of how elementary reactions occur through a series of averages over reagent velocity, internal energy, impact parameter, and orientation. To discover the effects of these variables on reactivity, it is necessary to carry out studies of chemical reactions far from equilibrium in which the states of the reactants are more sharply restricted and can be varied in a controlled manner. My research group is attempting to meet this tough experimental challenge through a number of laser techniques that prepare reactants in specific quantum states and probe the quantum state distributions of the resulting products. It is our belief that such state-to-state information gives the deepest insight into the forces that operate in the breaking of old bonds and the making of new ones.
Space does not permit a full description of these projects, and I earnestly invite correspondence. The following examples are representative:
The simplest of all neutral bimolecular reactions is the exchange reaction H H2 -> H2 H. We are studying this system and various isotopic cousins using a tunable UV laser pulse to photodissociate HBr (DBr) and hence create fast H (D) atoms of known translational energy in the presence of H2 and/or D2 and using a laser multiphoton ionization time-of-flight mass spectrometer to detect the nascent molecular products in a quantum-state-specific manner by means of an imaging technique. It is expected that these product state distributions will provide a key test of the adequacy of various advanced theoretical schemes for modeling this reaction.
Analytical efforts involve the use of capillary zone electrophoresis, two-step laser desorption laser multiphoton ionization mass spectrometry, cavity ring-down spectroscopy, and Hadamard transform time-of-flight mass spectrometry. We believe these methods can revolutionize trace analysis, particularly of biomolecules in cells.
