Menghan Liao is an associate research scientist in the Low-dimensional Quantum Materials Group at the Beijing Academy of Quantum Information Sciences. He obtained his B.S. degree from the School of the Gifted Young at the University of Science 

and Technology of China in 2015, and his Ph.D. degree from the Department of Physics at Tsinghua University in 2020. From 2021 to 2023, he worked as a postdoctoral fellow at the Department of Quantum Matter Physics at the University of Geneva. In 2024, he was awarded the Ambizione Project from the Swiss National Science Foundation and was promoted to a Scientific Collaborator (Research Associate). In 2025, he joined the Beijing Academy of Quantum Information Sciences. Menghan Liao is dedicated to the experimental study of novel quantum phenomena in low-dimensional materials, including (1) The mechanism of high-temperature superconductivity and other novel superconducting states; (2) Two-dimensional magnetic semiconductors; (3) Novel physical phenomena arising from topological band structures. Dr. Liao employs modern nano-fabrication techniques (such as van der Waals stacking and electron beam lithography) to prepare high-quality electrical devices and carries out electrical transport studies at low temperatures and high magnetic fields. Currently, all device fabrication and measurement tasks can be carried out in the Low-dimensional Quantum Materials Group and the Beijing Academy of Quantum Information Sciences. Until February 2025, Menghan Liao has published 23 papers and has been cited over 2000 times, and his H-index is 13. 9 papers were published as the first author or co-first author, including 1 Nature Physics, 1 Nature Nanotechnology, 1 Physical Review X, 2 Nature Communications, 3 Nano Letters, and 1 Applied Physics Letters. He has also led a Swiss National Science Foundation project with funding of about 7.5 million RMB. Menghan Liao has been awarded the "Academic Rising Star" by Tsinghua University, representing the highest academic achievement among graduate students. He has also received the National Scholarship, Outstanding Thesis Award, and the Outstanding Graduate Award from Tsinghua University.

We recruit PhD students and postdocs every year. Please contact us for details.
