Jose Valencia (Assoc)

Graduate student

Jose Valencia is a graduate student working on ultra-stable reference cavities for optical clocks. His work focuses on a cryogenic sapphire cavity that benefits from lower temperature and newer materials to improve the stability of optical resonators. As an undergrad, he was involved in Andrew Geraci's lab on mechanical cantilevers interacting with Rb transitions.
