Yelin is a theorist in quantum optics and quantum information whose work includes coherent line-narrowing theory for diamond NV centers, superradiant/cooperative effects in Rydberg systems and molecular ensembles, and quantum control of ultracold polar molecules. Included as theoretical support underpinning several quantum-sensing platforms (NV coherence, superradiant clocks) rather than as an experimentalist herself; she holds a joint appointment at the University of Connecticut.
