Research interests
My research interest lies in the gauge/gravity duality. This includes the renowned AdS/CFT correspondence and its extensions to Ricci-flat spacetimes. In the flat case, it has been proposed that asymptotically flat spacetimes are dual to Carrollian Conformal field theories in one lower dimension hosted at null infinity. These Carrollian field theories appear as the vanishing speed of light limit of relativistic field theories.
In these lines, I have been focused on Carrollian fluids and field theories, holographic reconstruction of Ricci-flat spacetimes in terms of Carrollian boundary data, and asymptotic symmetries and gravitational charges from a boundary perspective.
