Of Public Interest


Current Research

    I am currently a postdoctoral scholar at the Univeristy of Chicago in the Kavli Institute for Cosmological Physics. I work in the South Pole Telescope (SPT) collaboration, primarily on warm and cold digital frequency multiplexed (dfMux) readout and detector testing. I am additionally working on a sub-Kelvin SQUID architecture for dfMux.

PhD Research

    I am interested in Kinetic Inductance Detectors (KIDs) as candidate detectors for future Cosmic Microwave Background telescopes, including QUBIC. My PhD work focused on developing a prototype array for a 100 GHz lumped, direct-absorbing KID for CMB polarimetry. I designed the array using an EM simulation software and semi-analytic calculations, fabricated prototype arrays in the Detector Development Laboratory cleanroom facility at NASA Goddard, and tested the arrays in our ADR-cooled laboratory cryostat with our novel 100 GHz window-free, vacuum waveguide feedthrough-free optical coupling scheme. I demonstrated the first optical response in a KID at or below 100 GHz. A copy of my dissertation can be found here: Kinetic Inductance Detectors for CMB Polarimetry at 100 GHz.
