Research Summary
Dongsheng Ge studies how defects, boundaries, and interfaces reorganize quantum field theory and holography. His recent work treats localized RG flows, defect C-theorems, nonfactorizing interfaces, and interacting conformal line defects as tools for probing degrees of freedom that live on submanifolds rather than in the full bulk theory. In parallel, his work on holographic BCFT, Virasoro-subalgebra constructions of geometry, and brane scattering uses entanglement and boundary dynamics to connect quantum-information measures with gravitational dual descriptions.
