Graduate Students

Arthur Campello

I am a graduate student in the Applied Physics department. I received my bachelor's degree in physics and economics from Cornell University in 2020 and joined the Shen group in the fall of the same year. I am interested in using time-resolved ARPES to explore non-equilibrium behaviors of material electronic structures, including collective excitations and density waves. My research involves mapping these behaviors along time with high resolution and developing new time-resolved ARPES techniques to probe unobserved material phenomena.

Sophia Han

I am a graduate student in the department of applied physics. I received my B.S. degree in Physics from University of California, Santa Barbara in 2019 and joined Shen group in the fall of 2019. I am interested in studies of light matter interactions to explore exotic phases in quantum materials. Currently, I'm working on developing and utilizing the spin-resolved ARPES to further study the intrinsic spin textures of quantum materials.

Yingfei Li

Hi! I am a graduate student in department of applied physics and join in Shen's lab in Sept 2019 after receiving my B.S degree from Nanjing University. I am interested in intersection of strong correlations, topological order, high-temperature superconductivity. My research benefits a lot from world's-leading instruments of our group and illuminating discussions with our group members.

Jay Qu

I am a graduate student in the Physics department. I joined the Shen group late 2017, after completing my bachelor's degree at Harvard University. I am interested in understanding materials with exotic quantum states and phases, through the prism of the electronic structure. And so, I am excited to be part of efforts that utilitize novel time- and spin-resolved ARPES capabilities to study these materials through a whole new lens.

Ruohan Wang

I am a graduate student in the physics department. I joined Prof. Shen's group in autumn 2021 after receiving my B.S. degree from Rice University. I am interested in studying various emergent behaviors of quantum materials by exploring their electronic structures. Currently, my work focuses on investigating physical properties of oxide thin films and their heterostructures combining molecular beam epitaxy and angle-resolved photoemission spectroscopy.

Kejun (Ben) Xu

Hi! I'm from the land of true north (AKA Canada) and joined the Applied Physics department/Shen group in Sept 2016 after completing my undergrad at the University of Toronto. I'm interested in a wide range of problems in the field of quantum materials, although I'm currently working on scanning microwave microscopy of 2D systems and strongly correlated materials that exhibit metal-insulator transitions (MIT). Feel free to contact me with questions (no guarantees on answers though).
