The talk will focus on aspects of the Leigh-Strassler theory which is obtained by turning on all N=1 supersymmetry preserving marginal deformations in the N=4 Super Yang-Mills theory. Using a discrete non-abelian symmetry, we classify chiral operators in the theory. We present a conjecture regarding the spectrum of chiral primaries in this theory. We discuss the implications of the conjecture in the spin-chain approach to computing anomalous dimensions of operators. The gravity dual for this theory at arbitrary points in the space of couplings is not yet known. However, we will present an example where this theory is realized as the world-volume theory of D-branes. The marginal couplings however take specialized values and seem intimately related to a class of elliptic algebras called the Skylanin Algebras.
