Research

Research Interests:

My research focuses on fundamental questions about black holes and quantum gravity, utilizing tools from holography, geometry, and quantum field theory. Specifically, I study the origins of black hole entropy and identify the basic quantum building blocks of quantum gravity. This work is framed within the anti de Sitter/conformal field theory (AdS/CFT) correspondence, a framework that provides a fully consistent quantum description of gravity in asymptotically AdS spacetimes through a strongly coupled CFT in one fewer dimension. The strong coupling in the CFT presents significant challenges; however, for supersymmetric field theories, the localization principle simplifies the problem by reducing the infinite-dimensional path integral to a finite-dimensional integral, known as a matrix model. This allows for exact calculations in otherwise inaccessible strongly coupled field theories, thus providing precise predictions for quantum gravity through the lens of holography.
