I am a PhD student in Physics at HKUST, having started in Fall 2024. My research focuses on quantum phenomena in transition metal dichalcogenide (TMD) moiré superlattices.
I investigate systems such as twisted homo-bilayers and heterostructures, engineered through precise twist-angle control. These moiré potentials give rise to exotic electronic phases, including fractional Chern insulators, superconductivity, correlated insulating states, and topological phases.
Using low-temperature photoluminescence (PL) spectroscopy—often under external magnetic fields—I probe excitonic signatures as sensitive indicators of emergent quantum states and material properties.
My goal is to uncover novel quantum matter in these highly tunable platforms and to contribute to the foundational design principles for topological quantum devices and neuromorphic optoelectronics.
