Research Interests

  • Development, fabrication and application of metallic magnetic calorimeters (MMCs) and magnetic penetration depth thermometers (MPTs), in particular for high-resolution X-ray spectroscopy and the direct determination of the electron neutrino mass.
  • Development, fabrication and application of superconducting quantum interference devices (SQUIDs) and SQUID based multiplexing techniques, in particular for the readout of low-temperature microcalorimeters.
  • Development and establishment of microfabrication processes for the fabrication of low-temperature particle detectors and Josephson junction based quantum devices.
  • Investigation of low-frequency excess flux noise of superconducting quantum devices.
