My research interests are in the field of String theory and its applications to Quantum Field Theory and Quantum Gravity. Much of my recent work has focussed on exploiting the the AdS/CFT correspondence to strongly coupled field theories and to understand how the holographic map between field theory and gravity works.

For basic introduction to String theory and AdS/CFT correspondence with some useful set of references follow the links.

## Current research directions:

I am currently interested in:

- Entanglement entropy and its holographic avatars
- Quantum information and its implications for quantum gravity
- Non-equilibrium dynamics in QFT
- Applications of the Schwinger-Keldysh formalism
