Research Interests:
My research is focused on developing superconducting electronics for sensing across much of the electromagnetic spectrum. For example, superconducting sensors can be used for high-resolution gamma-ray spectroscopy, and for the detection of astrophysical millimeter-wave radiation from the cosmic microwave background. Current research projects include very basic topics (what is the resistance mechanism in thin-film superconducting sensors?) and very applied topics (the construction and delivery of complete instruments to various observatories). Devices of interest include transition-edge thermal sensors, kinetic inductance sensors, superconducting quantum interference devices (SQUIDs), and tunnel junction refrigerators.
