Yecun Wu
Postdoctoral Scholar, Physics
BioDr. Yecun Wu is a postdoctoral scholar in the physics department at Stanford University, working with Prof. Steven Chu. His research interests encompass a range of interdisciplinary fields, including quantum sensing, quantum materials, energy storage, and sustainability. Dr. Wu's current research aims to tackle the pressing issues and challenges in the energy field by utilizing quantum technology. He received his Ph.D. in Electrical Engineering from Stanford University, where he worked with Prof. Yi Cui and collaborating closely with Prof. Harold Y. Hwang. During his doctoral studies, he developed innovative methods to control the properties of two-dimensional materials using guest species, which opened new avenues for their use in quantum and energy applications.

Lin Xin
Postdoctoral Scholar, Physics
BioLin Xin is a Postdoctoral Scholar in the Physics Department at Stanford University. He received his Ph.D. from the Georgia Institute of Technology, following undergraduate studies at Shanghai Jiaotong University. His current research centers on advancing optical control of interactions among laser-cooled atoms, with an eye towards applications in quantum simulation, metrology, and computation. He has developed protocols in quantum optimal control for entanglement-enhanced eigenstates in spinor Bose-Einstein condensates.

Chunchen Xu
Postdoctoral Scholar, Psychology
BioI am currently a postdoc researcher at the Psychology Department at Stanford University. I study culture and the self in the context of AI-based smart technological developments. The first line of my work focuses on understanding and critiquing extant technological systems from a cultural perspective. I unpack cultural assumptions underlying conceptions of smart technology and examine technology's social and psychological impact. The second line of my work seeks to untether the self from extant mainstream meaning systems and open the space of the imaginary. I explore how historically marginalized cultural worldviews offer clues for diversifying conceptions of smart technology towards building a more equitable society and a caring ecology.

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. -
Rebecca Zhu
Postdoctoral Scholar, Psychology
BioI am a postdoctoral fellow in developmental psychology at Stanford University, working with Michael C. Frank. Previously, I was a PhD candidate and postdoctoral fellow at the University of California, Berkeley, working with Alison Gopnik, and a lab manager at Harvard University, working with Susan Carey.
My research investigates when and how children acquire, and consequently learn from, symbolic systems such as language and pictures. In one line of research, I investigate the mechanisms underlying children’s acquisition of various kinds of non-literal language, such as metaphor and metonymy, as well as how children’s non-literal language comprehension may further guide their thinking and reasoning. In another line of research, I work with urban and rural Kenyan children to investigate the efficacy of picture-based learning materials and the validity of picture-based assessments across cultures and contexts. My work in Kenya is conducted in close collaboration with researchers and non-profit organizations in Kisumu, Mombasa, and Nairobi.
This research program is innovative and interdisciplinary: these findings not only address fundamental debates in psychology, philosophy, and linguistics (i.e., by providing empirical insight into the mechanisms underlying children’s ability to acquire and learn from symbolic systems), but also have direct implications for applied research in education, public health, and developmental economics (i.e., by improving the learning materials and assessment tools used in global early childhood development programs).
