My research interests lie in the field of conformal field theory, sigma models and mathematical physics.
In particular, my past research was related to integrable deformations of sigma models and the analysis of their behavior as the renormalization group time tends to minus infinity. This kind of analysis allows one to construct a dual description of the sigma model as a Toda field theory, which has a much better UV behavior: the dual theory has a finite number of counterterms and allows one to perturbatively construct the S-matrix. In addition, I studied N=2 supersymmetric sigma models and, in particular, the calculation of the beta function in higher loops.
At the moment, I am studying ways to construct cosets of conformal field theories through the prism of their associated W-algebras, as well as the construction of gluing such theories.
