research

I work in theoretical high energy physics, specifically in quantum field theory, gravitational physics and string theory.

An updated list of my publications can be accessed through the following links: inSPIRE, Google Scholar.

Some specifics:

I am interested in understanding the workings of the Holographic Principle, which is an enigmatic correspondence between gravity and non-gravitational theories in one lower dimension. I also work on string theory and quantum field theories, with a focus on unconventional symmetries, beyond the usual relativistic domain. Below are some details.

Holography for Asymptotically flat spacetimes

The main focus of my recent research has been the attempt at a formulation of holography for asymptotically flat spacetimes, away from its usual setting in Anti de Sitter spacetimes. During the 2010s, my collaborators and I mainly concentrated our attention on three dimensional gravitational theories where the formulation of the problem is made easier by the existence of a large number of symmetries.

My current focus is the formulation of Flat holography in the physically relevant four dimensions. Our approach is now called the Carrollian approach and posits a co-dimension one dual field theory living on the null boundary. This is to be contrasted with the Celestial approach to flat holography, which proposes a dual CFT living on the co-dimension two celestial sphere at infinity.

Tensionless strings

I am interested in understanding various singular limits of string theory. A particularly enigmatic domain is the tensionless limit of strings that offers a window into the behaviour of string theory at ultra high energies.
