About
Anthony R. Kerr is a Visiting Professor in Electrical and Computer Engineering, affiliated with the National Radio Astronomy Observatory (NRAO) in Charlottesville, VA. His career spans over five decades, with foundational contributions to radio astronomy instrumentation and superconducting device technology.
Dr. Kerr holds a Ph.D. from the University of Melbourne (1969). He has pioneered advancements in cryogenic parametric amplifiers, Schottky-diode mixers, and SIS (Superconductor-Insulator-Superconductor) mixers for millimeter/submillimeter wavelengths. His work at NASA/Goddard Space Flight Center and NRAO focused on low-noise receiver technology, culminating in breakthroughs for the Atacama Large Millimeter/submillimeter Array (ALMA).
His research interests emphasize receiver sensitivity optimization, quantum-limited detection, and millimeter-wave instrumentation. Key innovations include wideband SIS mixers, cryogenic cooling systems, and standardized waveguide interfaces for submillimeter astronomy.
