I will survey some recent results about the structure of II_1 factors arising from group actions on free group factors obtained via Voiculescu's free Gaussian functor. These results provide a new class of II_1 factors with no Cartan subalgebra as well as new examples of maximal amenable subalgebras in II_1 factors.
