About Shen Lab

We focus on the emergent properties in quantum materials and related novel tool developments.

We study a variety of materials, such as high-temperature superconductors, topological insulators, and quantum materials at atomically thin limit. By probing their interactions with electromagnetic radiation, ranging from x-rays, to the ultraviolet, and into the microwave regime, we gain insight into the underlying physics governing the emergent properties in these condensed matter systems.


Our current research involves the study of emergent properties in quantum materials. Our primary experimental tool is angle-resolved photoemission spectroscopy (ARPES), but we also perform experiments using resonant x-ray scattering and near-field microwave microscopy techniques. Our research also involves the exploration of materials inspired by applications, such as novel diamondoids as novel materials template.


Dr. Shen is the Paul Pigott Professor in Physical Sciences, Professor of Physics, Applied Physics and SLAC Photon Science Departments, as well as a senior fellow of the Precourt Institute for Energy, at Stanford University. He is also the Advisor for Science and Technology of SLAC National Accelerator Laboratory and a member of the faculty advisory board of the Knight-Hennessy Scholars program at Stanford University. Over the last three decades, he has mentored more than eighty graduate students and postdoctoral associates. Over forty of them are now faculty members of research universities and about ten of them become scientific staff of national laboratories and research institutes.
