My research interest is the fundamental nature of spacetime, quantum field theory, and the profound connections between them. I have worked on holography (AdS/CFT) to learn new lessons about quantum gravity and quantum systems at strong interaction. I lead a high-energy physics team, 『Quantum Information, Black Holes, and Holography』, as part of the JRG program at APCTP. My up-to-date publication records are available on INSPIRE-HEP and Google Scholar.
