Short Bio

After graduating from HKUST in 2003, I moved to Brown University for graduate study and received my PhD degree in 2008. After spending one year as a joint postdoc fellow of HKUST-IAS and MIT, I moved to MIT in 2009 as a Croucher Postdoc Fellow. I joined the HKUST physics department in 2011. 

Research Interests

In general, I am interested in theoretical condensed matter physics with emphasis on topological materials, moiré materials and unconventional superconductors. Currently, our group is studying 1. The Berry curvature multipole (such as quadrupole) induced higher order anomalous Hall effects; 2. The electron interaction-induced correlated states in twisted bilayer graphene and moiré transition metal dichalcogenides; 3. Quantum metric effects in flat band superconductors and magnets; 4. The realization of topological and other superconducting qubits using Majorana zero modes and unconventional Josephson junctions. 5. Heesch Weyl fermions (a new type of Weyl fermions we discovered) in anti-ferromagnets. We are looking for PhD students and postdocs to explore these areas at HKUST.
