Marom joined the University of Texas at Austin as a postdoctoral researcher in 2010. She moved to Tulane University as an assistant professor in physics in 2013. In 2016 Marom was appointed as an assistant professor at Carnegie Mellon University. She is a member of the Pittsburgh Quantum Institute.
Her work considers molecular crystals that are bound by Van der Waals interactions. As Van de Waals interactions are weak, molecules can adopt a range of crystal structures. These are known as polymorphs, and can be predicted using computational simulations. The chemical and physical properties of these systems are determined by their crystal structure. Maron develops genetic algorithms that predict the structure of molecular crystals using the principles of survival of the fittest. Marons work uses density functional theory and many-body perturbation theory to study complex atomic systems. She has investigated the GW approximation for molecules. The materials investigated by Marom can be used for dye-sensitized solar cells.
