Knirck builds novel microwave- and mm-wave-frequency detectors (ADMX resonant cavities, MADMAX dielectric haloscopes, and the broadband BREAD/dish-antenna concept) to search for axion dark matter, explicitly leveraging cutting-edge single-photon quantum sensing to push beyond the standard quantum limit. He describes axion searches as sitting directly at the intersection of particle physics, astrophysics, photonics, and quantum sensing, and is building a new experimental group at Harvard.
