SUDHIR KUMAR SAHU, Postdoctoral Research Associate

(Joint appointment at NIST Boulder)

Sudhir did his Ph.D. at the Indian Institute of Science, Bengaluru (India). For his Ph.D., he developed a cavity electromechanical device for investigating the change in elastic response of a high-Tc superconductor due to electric charges associated with vortex cores. His research interests include cavity electromechanics, superconducting circuit QED, and quantum hybrid devices. Apart from research, he enjoys photography, and playing cricket and badminton. 

DEBSUVRA MUKHOPADHYAY, Postdoctoral Research Associate

Debs completed his Ph.D. in Physics from Texas A&M University, followed by a short postdoctoral stint at Washington University in St. Louis where he explored the multiphoton excitation regime of waveguide QED. He joined the QUEST group in April 2024, where he plans to investigate cooperative and non-Markovian effects in waveguide QED and engineered open quantum systems. Outside research, he enjoys traveling, watching travel vlogs, and keeping up with current events. Additionally, he is an avid chess enthusiast, and can be found engrossed in playing speed chess and solving chess puzzles in his free time.

JIRU LIU, Postdoctoral Research Associate

Jiru earned his Ph.D. in Physics from Texas A&M University advised by Prof. M. Suhail Zubairy, following his bachelor's degree from the University of Science and Technology of China. During his doctoral research, he worked on various topics, such as quantum entanglement, continuous-variable systems, and quantum metrology. In September 2024, he joined the QUEST group as a postdoctoral scholar, where he plans to focus on designing novel superconducting quantum circuits. Jiru has a deep love for art; one example is his enthusiasm for collecting fountain pens and practicing calligraphy.

LE HU, Postdoctoral Research Associate

Le earned his B.S. in Physics from University of Michigan, Ann Arbor and his Ph.D. in Physics from the University of Rochester advised by Prof. Andrew N. Jordan. His doctoral studies spanned multiple areas such as quantum metrology, quantum control, quantum foundations, open quantum systems and entanglement dynamics. He joined the QUEST group as a postdoctoral scholar in Fall 2024, where he will continue to explore non-equilibrium effects in quantum systems along with his interests in fundamental aspects of quantum physics. 

JUZAR THINGNA, Visiting Scientist

Juzar did his Ph.D. in Quantum Transport at the National University of Singapore. After postdocs in Germany, Singapore, Luxembourg, and South Korea he joined the QUEST group in May 2022 as a postdoctoral associate, before transitioning to a visiting scientist position in June 2023. He primary research interests are quantum open systems, quantum transport, and quantum thermodynamics.
