He is mainly engaged in the study of the interaction between light and matter. Specific research directions include:
(1) Light field regulation and quantum entanglement manipulation based on photon spin and high-dimensional orbital angular momentum.
(2) The interaction of the photon's spin with high-dimensional orbital angular momentum and artificial structural materials (metasurface, waveguide, etc.).
(3) The application of photon spin and high-dimensional orbital angular momentum in topological photonics.
