I am mainly working on the ultrafast carrier dynamics in 2D materials (graphene, TMDCs, etc.) with fully quantum-mechanical methods and built an excellent intuitive understanding of low-dimensional physics. I am also working on the fundamental theory of topology, symmetry, and geometric effects in graphene and other 2D materials.

1. Quantum geometry and topologcal properties in low-dimensional interacting system.

2. Nonlinear optical response and carrier dynamics in Dirac materials.

3. Quantum spin liquid and fractional Chern insulator.
