Recent developments in non-Abelian T-duality in string theory

Synopsis: We briefly review the essential points of our recent work in non-Abelian T-duality. In particular, we show how non-Abelian T-duals can effectively describe infinitely high spin sectors of a parent theory and how to implement the transformation in the presence of non-vanishing Ramond fields in type-II supergravity.
