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. Zhuoyu Chen
I joined the Shen group in April 2018 as a postdoctoral researcher. I obtained my B.S. in Mathematics and Physics from Tsinghua University, Beijing, China in 2012. I received my Ph.D. in Applied Physics from Stanford University, California, USA in April 2018. For my doctoral thesis, I studied the dual-gate controlled two-dimensional ground states of a superconducting oxide interface, using pulsed laser deposition for sample synthesis and dilution refrigerator for low-temperature transport measurements. My current interest is to study superconductivity and correlated electrons combining oxide/chalcogenide molecular beam epitaxy, scanning probe microscopy, and angle-resolved photoemission spectroscopy.
Dr. Bing Cheng
I joined the Shen group in October 2019 as a postdoctoral scholar after finishing my Ph.D. study in the Johns Hopkins University. My Ph.D. research mainly focuses on the study of low-energy electrodynamics in topological materials such as Dirac and Weyl semimetals, using time-domain magneto terahertz spectroscopy. My current interest is to use time-resolved spectroscopic tools to study ultrafast dynamics in quantum materials. One major goal of my postdoctoral research is to develop a THz pump setup for time-resolved ARPES and use it to study Higgs physics in superconductors. I will also be involved with the studies of topological materials and correlated electron systems using other ultrafast techniques such as THz pump X-ray probe and THz pump optical probe.

I joined the Shen group as a postdoctoral researcher in September 2021 supported by the Q-FARM Bloch Fellowship. I obtained my BS degree in physics at East China Normal University, Shanghai, China in 2016 and my PhD degree in condensed matter physics at Fudan University, Shanghai, China in 2021. During my PhD study, my research focuses on magnetic two-dimensional materials and their electronic transport properties. My current research interest is to investigate the emergent properties of exfoliated two-dimensional materials and their heterostructures using angle-resolved photoemission spectroscopy and scanning microwave impedance microscopy.

I joined Shen group in August 2020 as a postdoctoral researcher. I obtained my B.S, M.S and Ph.D degrees in physics from Pusan National University in Korea. During my Ph.D, I studied the electronic correlations in graphene using angle-resolved photoemission spectroscopy. My current research interests are the growth of 2D materials using molecular beam epitaxy and understanding their physical properties using angle-resolved photoemission spectroscopy.
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.

I joined Shen group as a postdoctoral researcher in September 2021. I received my BS degree in Physics from Nankai University and PhD degree in condensed matter physics from Tsinghua University. During my Ph.D, I mainly studied interfacial superconductivity and topological properties in novel low dimensional materials, using molecular beam epitaxy and scanning tunneling microscopy. My current research interest is to investigate the high-Tc superconductivity in epitaxial grown oxide/chalcogenide thin films with angle-resolved photoemission spectroscopy.
