I present results about the structure of a wide class of infinite groups which were obtained in collaboration with Jesse Peterson (Berkeley). Using group cohomology with coefficients in l^2G, we obtained new information about the subgroup structure of negatively curved groups. These results generalize several central results in geometric and combinatorial group theory.
