Research Interests:

Experimental condensed matter physics, with a focus on quantum transport in low-dimensional quantum materials. Current efforts center on developing novel device fabrication and control techniques to explore emergent electronic phenomena. Representative achievements include the discovery of superconductivity in bilayer nickelate thin films under ambient pressure, the realization of monolayer cuprate superconductors, the first observation of the quantum anomalous Hall effect in an intrinsic magnetic topological insulator, and the development of alumina-assisted exfoliation and ionic gating techniques for two-dimensional materials.
