Research Interests |

I am working on various aspects of string theory: D-branes backreaction: Gravity in stringy braneworlds scenarios. Supergravity solutions for open strings. AdS/CFT and Integrability: Line operators in
quantum integrable sigma models. Perturbative derivation of the Hirota equation.Sigma models on supergroups: Non-chiral current algebra. Perturbative computation of the spectrum. Superstrings in curved non-compact spacetimes: Liouville theory and exact string backgrounds. Boundary states description of D-branes. |
