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. -
Pavan Yadav
Postdoctoral Scholar, Chemistry
BioI am a Postdoctoral Researcher at Stanford University in the laboratory of Professor Paul A. Wender, where I work on the development of delivery technologies for RNA therapeutics, including mRNA, circular RNA (circRNA), and oligonucleotide-based medicines. My current research focuses on lipid nanoparticles (LNPs) and transporter-based systems for targeted nucleic acid delivery, with the goal of advancing the translation of genetic medicines.
I received my Ph.D. in Pharmaceutical Sciences from CSIR–Central Drug Research Institute (CSIR-CDRI), India. During my doctoral training, I specialized in nanomedicine, drug delivery, pharmacokinetics, and bioanalytical method development, with a particular focus on developing nanocarrier-based therapeutic strategies for cancer treatment. Prior to my Ph.D., I earned both my Bachelor of Pharmacy and Master of Pharmacy degrees from Mahatma Jyotiba Phule Rohilkhand University, India.
My research interests span RNA therapeutics, drug delivery, nanomedicine, lipid nanoparticle engineering, pharmacokinetics, and translational pharmaceutical sciences. I have experience in the design, formulation, and biological evaluation of diverse delivery systems, including lipid nanoparticles, liposomes, nanoemulsions, polymeric carriers, and other nanomaterial-based therapeutic platforms. My work integrates formulation science, biological evaluation, and preclinical studies to improve the delivery and performance of therapeutic agents.
I have authored more than 35 peer-reviewed publications in journals such as Nature Communications, ACS Applied Materials & Interfaces, International Journal of Pharmaceutics, Nanomedicine, and Bioanalysis. I am particularly interested in developing innovative delivery approaches that bridge fundamental research and clinical translation, with the ultimate goal of improving treatment options for patients. -

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. -
