I will discuss recent advances in addressing the heterotic moduli problem in six and seven dimensional compactifications. To map out the reduction to a lower dimensional effective theory, and in a quest to complete our understanding of the generically torsional geometries that appear, it is important to have a good understanding the moduli of these geometries. I will review the infinitesimal moduli space in six dimensions, and comment on some recent advances in understanding its geometric properties, in addition to higher order deformations and obstructions. I will then explain how a similar story is emerging in seven dimensional compactifications on more exotic manifolds with G2-structure, giving hope that similar tools can be applied to understand moduli in other areas of string theory, with possible applications to phenomenology and AdS/CFT.
