Research interests

My research interests include string theory, supergravity, differential geometry and integrability in the AdS/CFT correspondence. I obtained various results about the quantum behaviour of massless modes appearing in integrable AdS2 and AdS3 string backgrounds. In particular I proposed a new geometric interpretation of their scattering matrix. I studied problems related to supersymmetric solutions of heterotic supergravity with alpha prime corrections, in particular regarding their classification and the supersymmetry enhancement mechanism for near-horizon geometries. Recently, I am working on non-relativistic string theory, aiming to a non-relativistic formulation of the AdS/CFT correspondence and questioning about its integrability.
