Dressel's institute specializes in broadband electrodynamic spectroscopy -- microwave through THz to optical -- of low-dimensional and strongly correlated electron systems: organic conductors, quantum spin liquids, superconductors, and quantum magnets, complemented by ESR/EPR and low-temperature transport. Relative to the established NV-ensemble quantum-sensing playbook (DEER, nanoscale NMR, T1 relaxometry at pT/sqrt(Hz) ensemble sensitivity), a borderline inclusion, kept because the group's core competence is high-sensitivity resonant detection of weak electrodynamic responses (and it houses ESR capability), which is adjacent to spin-ensemble sensing even though the scientific target is the material rather than the sensor.
