Dr. Chun Lin

I am a joint research associate between SSRL/SLAC and Shen group, having started in April 2024. I completed my master and doctoral degrees in science at the University of Tokyo, during which my research interests were observing the band structure of electron–doped cuprates and strain engineering electronic states in topological materials. My current interests involve improving and developing modern ARPES systems (working closely with Dr. Makoto Hashimoto and Dr. Donghui Lu) and studies of exotic quantum phenomena utilizing uniaxial strain in both weakly and strongly correlated systems.

Dr. Denny Puntel

I received my PhD in Physics at the University of Trieste, Italy, working in the T–ReX group at Elettra Sincrotrone. My scientific interests focus on the properties of topological insulators and strongly–correlated systems, particularly copper–based superconductors, investigated by time– and angle–resolved photoelectron spectroscopy. In January 2024, I joined Prof. Shen’s group efforts to explore the ultrafast physics of these systems by state–of–the–art light sources and spectroscopic tools. In this framework, a core aspect of my research at Stanford and SLAC is to advance the exploitation of soft X–ray time–resolved photoemission using free–electron laser light. [Email]


Dr. Bai Yang Wang

I joined Shen group as a postdoctoral researcher in November 2023. I completed my undergraduate degree at University of Wisconsin–Madison before a PhD in Physics at Stanford University. In my PhD I combined pulsed laser deposition and low temperature transport measurement techniques to investigate the infinite–layer nickelate superconductors and developed in–situ strain tuning of freestanding cuprate membranes. My current research interest is to use oxide molecular beam epitaxy and spectroscopic methods to investigate the novel properties of various quantum materials. [Email]


Dr. Paulina Majchrzak

I joined the Shen group as a Stanford Energy Postdoctoral Fellow in September 2023. I completed my Masters degree in Chemical Physics at the University of Edinburgh, Scotland, in 2019, and my PhD degree at Aarhus University, Denmark, in 2023. During my PhD, I investigated non–equilibrium phenomena in novel low–dimensional materials and their functional devices. At Stanford, I am working towards developing in–operando spectroscopic methods for studying rechargeable battery cathodes. [Email]


Dr. Mark Barber

I joined the Shen group as a postdoctoral researcher in August 2019 supported by the Marvin Chodorow postdoctoral fellowship. I completed my undergraduate degree at the University of Cambridge before a PhD from the University of St. Andrews and Max Planck Institute for Chemical Physics of Solids. In my PhD I worked on novel methods for applying and controlling uniaxial stress, and applied these techniques to study a variety of strongly correlated electron systems. My current research uses scanning microwave impedance microscopy, MIM, to look at the real space dependence of conductivity and permittivity in a variety of quantum materials/devices.

Dr. Zhurun (Judy) Ji

I joined the Shen group as a postdoctoral researcher in August 2021 supported by the Stanford Science fellowship and Urbanek- Chodorow postdoctoral fellowship. I completed my undergraduate degree at the USTC before a PhD from the University of Pennsylvania. In my PhD I focused on developing and understanding optoelectronic properties of topological materials both experimentally and theoretically. My current research uses scanning microwave impedance microscopy to study nanoscale optoelectronic behaviors in various quantum material systems.

Dr. Yong Zhong

I joined Shen group in August 2019 as a postdoctoral researcher. I obtained my B.S. degree in Mathematics and Physics from Nanjing University in 2012. I received my Ph.D. degree in Physics from Tsinghua University in 2019. In my Ph.D. work, I studied the electronic structures of cuprates using molecular beam epitaxy and scanning tunneling microscopy. My current research focuses on the emergent properties of transitional metal dichalcogenides using synchrotron-based spectroscopic methods.
