Johannes Hubmayr (Fed)
Dr. Johannes Hubmayr is an experimental physicist and Group Leader in the Quantum Electromagnetics Division. He joined NIST in 2010. His Group designs and micro-fabricates custom cryogenic sensor arrays and multiplexed readout for applications in cosmology, astrophysics, security, and increasingly in support of quantum information science. In one research theme, the Group works in large scientific collaborations to build millimeter-wave cameras that make exquisite measurements of the cosmos to understand fundamental physics, how the universe began, how it has evolved, and to determine the values of cosmological parameters such as the physical baryon density to high precision. Dr. Hubmayr’s areas of technical expertise include large-format cryogenic focal planes, transition edge sensor (TES) bolometers, microwave kinetic inductance detectors (MKIDs), millimeter-wave polarimetry, SQUID multiplexed cryogenic readout, microfabrication design, and millimeter-wave feedhorns. As of early 2023, Dr. Hubmayr’s 300+ scientific publications have been cited 11,400+ times.
