Experimental cosmologist building and operating CMB telescopes. Directions: (1) South Pole Telescope — PI of SPT series; SPT-3G currently mapping CMB temperature and polarization at arcminute resolution; (2) thermal and kinematic Sunyaev-Zel'dovich effect mapping for galaxy cluster cosmology; (3) CMB gravitational lensing for large-scale structure; (4) CMB-S4 design and planning. Argonne joint appointment. APS and AAAS Fellow.

Reichardt leads Melbourne's CMB effort and is a member of SPT-3G, the third-generation South Pole Telescope camera, whose focal plane is populated by ~16,000 transition-edge sensor bolometers read out by SQUID multiplexers. His science targets are CMB lensing, the Sunyaev-Zel'dovich effect and the small-scale temperature and polarisation power spectra; the enabling technology is cryogenic quantum-limited detection. Positioned against the established body of NV-ensemble quantum sensing work — DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity — this is the astronomical analogue of the same problem — a detector whose noise floor is set by fundamental quantum limits rather than by the source — and TES/SQUID readout is a natural pivot for a physicist trained on pT/sqrt(Hz) magnetometry, since SQUID amplification is the shared hardware. Preferred attribute present: astronomy where the quantum sensor is the enabling technology.
