Dr. Xiaoyu Liu’s research focuses on correlated and topological phenomena in quantum materials. She received her Ph.D. in 2020 from Tsinghua University under the supervision of Prof. Wenhui Duan, where she employed first-principles calculations to study topological materials. She then joined the University of Toronto as a postdoctoral researcher with Prof. Hae-Young Kee, investigating the microscopic origins of spin models and the realization of strong Kitaev interactions relevant to quantum computing. In 2022, she moved to the University of Washington to work with Prof. Di Xiao on moiré quantum materials, focusing particularly on twisted transition metal dichalcogenides.

In 2025, Dr. Liu joined BAQIS, where she continues to explore emergent quantum phases in strongly correlated systems such as moiré materials and spin models. Her current work aims to uncover novel topological and magnetic phenomena arising from the interplay of electronic correlation, topology, and moiré engineering, with the broader goal of identifying new quantum platforms that could host exotic quasiparticles and support future quantum technologies.
