Subsequently, she worked as a post-doctoral research associate at the Joint Institute for Laboratory Astrophysics (JILA) with Jun Ye on atomic lattice clocks.
Zelevinsky performed seminal work on the strontium optical lattice clock in the group of Jun Ye at JILA and was the first to use narrow-linewidth laser light to create diatomic molecules of this class in an optical lattice at ultracold temperatures, determining their molecular binding energies to a greater precision than was previously achievable in molecular beam and heat-pipe studies.
[3] Together with Robert Moszyński and her students, Zelevinsky settled a long-standing question about the role of quantum interference in the angular patterns of molecular photofragments.
Zelevinsky is also one of the principal investigators of the CeNTREX collaboration with David DeMille to search for the deformation in the shape of atomic nuclei known as a Schiff moment using the thallium fluoride molecule.
While an undergraduate at Massachusetts Institute of Technology, Zelevinsky attended a summer school on atomic physics in Los Alamos.
