Interests
My recent research interest focuses on perturbative and non-perturbative aspects of quantum field theory, quantum gravity and string theory.One of my main areas of activity has been developing and exploiting modern powerful techniques of scattering amplitudes, which includes two main research directions: 1. new formulations of scattering amplitudes in terms of twistor theory and Grassmannian geometry; 2. applying modern techniques of scattering amplitudes to other research areas.
Over the past few years, new twistor-like formulas have been discovered for scattering amplitudes in a wide range of interesting theories, including the world-volume theory of single probe brane in M-theory and string theory. These new mathematical formulas not only provide concrete formulas for the amplitudes in these theories, but also reveal new structures. This research direction is to discover such new formulations for more theories and explore the implications.
My other major line of work is to study the applications of scattering amplitude techniques in other research areas. In particular, I am interested in understanding the symmetry constraints on effective actions in the language of scattering amplitudes. Scattering amplitudes provide extremely efficient ways of imposing the constraints, in the form of, for instance, soft theorems, unitarity and superamplitude consistency.
Recently, I have also been interested in exploring deep connections between flat-space amplitudes and holographic correlation functions in AdS space. Holographic correlators resemble many properties of flat-space scattering amplitudes, especially when formulated in Mellin space. This allows us to apply "amplitude-inspired methods" to study these correlators at the level of supergravity limit and beyond.
