String Theory is an extra-dimensional theory. The extra-dimensions of space in it are curled up onto themselves in non-trivial ways and effect the physics of the 4D. This gets more non-trivial when we add things like warping, fluxes and non-perturbative effects to create more phenomenologically interesting backgrounds. In order to understand the 4D EFT better, we need to understand the maping of degrees of freedom from 10D to 4D. This has been done historically using supersymmetry but in scenarios with little to no SUSY, one can use supergravity equations of motion techniques to derive the 4D EFT atleast upto second order in fluctuations. My research deals with doing this dimensional reduction and and studying the non-trivial EFTs that emerge from it.

Scattering amplitudes are one of the most "close to observable" features of quantum field theory. It has been seen that demanding specific features of amplitudes can help us understand the space of field theories better. Currently I am investigating the nature of 4-graviton scatterings in EFTs that come from warped extra-dimensions to hunt for Regge growth. Regge growth has been shown to be closly linked to causality which is an important lamp post for physical EFTs.
