Avirup Roy (IntlAssoc)

Avirup Roy is a Postdoctoral Associate through the PREP program between NIST and the University of Colorado, Boulder. He is associated with the Quantum Calorimeters Group within the Quantum Sensors Division at PML, NIST. His current research interests include the design and testing of superconducting detector-based large-format X-ray spectrometers for beamline science and contributing to the development of novel X-ray detector calibration techniques for metrology and future space missions.

Previously, as a graduate student at the University of Wisconsin, he was involved in a successful NASA sounding rocket campaign to the Northern Territory, Australia, to make first-time, high-resolution measurements of the X-ray emission from the center of the Galaxy. He was also involved in the fabrication and testing of superconducting X-ray detectors for future space instruments.
