My main research interests focus on the various physical and mathematical problems in quantum field theory and gravity. More precisely, in the past few years, I have been working in

1.Entanglement entropy and its implicatioon in AdS/CFT correspondence;

2.Integrability in AdS/CFT;

3. Semi-classical AdS3 gravity.

4. Black hole physics: its holographic description, large D expansion, shadow and gravitional wave;
