  We construct the supergravity duals of marginal deformations of a (0,2)
Landau-Ginsburg theory that describes the supersymmetric lowest Landau level.
These deformations preserve supersymmetry and it is proposed that they are
associated with the introduction of a phase in the (0,2) superpotential. We
also consider marginal deformations of various field theories that exhibit
Schrodinger symmetry and Lifshitz scaling. This includes countably-infinite
examples with dynamical exponent z=2 based on the Sasaki-Einstein spaces
Y^{p,q} and L^{p,q,r}, as well as an example with general dynamical exponent z
>= 1.
