Kelsey Morgan (Fed)

Dr. Kelsey Morgan is a research physicist the Quantum Calorimeters Group within the Quantum Electromagnetics Division at NIST Boulder and research faculty at the University of Colorado Boulder. Dr. Morgan's research focuses on developing superconducting detectors, primarily transition-edge sensors, for X-ray and gamma ray spectroscopy. Application areas of interest for these detectors include astronomy, chemistry, biology, materials science, nuclear security, and measurement standards. Dr. Morgan is also interested in studying the physics of superconducting thin films and superconducting detectors, and advancing multiplexing techniques for large arrays of superconducting detectors.
