Research interests

My research focuses on the study of M-theory and string theory using covariant methods (exceptional and double field theory), primarily on the development of polyvector deformation techniques for supergravity solutions, which generalize Yang-Baxter deformations. This approach is used to investigate integrable structures of two- and three-dimensional sigma models, formulate generalized supergravity, and study the exceptional symmetries of the theory. Key results include generating new solutions with fluxes, describing holographic renormalization group flows in conformal field theories, and classifying the non-geometric sectors of the theory.
