The scientific driver of our research is the search for axions, one of the leading candidates to be the universe's dark matter. Axions are elusive particles—they interact very feebly and weigh orders of magnitude less than any of the known particles. In order to find them, we build cryogenic experiments that rely on superconducting quantum sensors to detect the tiny signals that we expect when axions interact with magnetic fields.

We primarily work in two mass ranges: neV-scale axions with the DMRadio experiments, and meV-scale with BREAD. As a part of this work, we develop superconducting quantum sensors, including qubit-based sensors (SQUATs) for THz photon detection.
