Department(s)/lab(s): Physics (Cavendish Laboratory) | Oswald Pulsar Group @ Cambridge
Summary:

Oswald applies modern data-driven and machine-learning techniques to enormous datasets from large pulsar surveys (Parkes Young Pulsar Array, MeerKAT Thousand-Pulsar-Array) to understand pulsar radio emission mechanisms, polarization behaviour and the structure of the Galactic magnetic field.

Department(s)/lab(s): Physics | Astrophysics Group @ Imperial
Summary:

Owen works on the theory and observational consequences of protoplanetary disk evolution, photoevaporation and exoplanet demographics, explaining features such as the observed radius gap in close-in exoplanets.

Department(s)/lab(s): School of Physics | Melbourne CMB Cosmology Group (Reichardt) @ UMelb
Summary:

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.

Department(s)/lab(s): Physics | Seager Group (Exoplanets and Habitability) @ MIT
Summary:

NON-PREFERRED (astronomy pivot, kept for review). Seager's group works on exoplanet atmosphere and interior characterization and the search for atmospheric biosignature gases, including leadership of space-mission concepts (Starshade, ASTERIA, TESS deputy science direction) that require high-contrast, high-resolution spectroscopic instrumentation; per public reporting she is departing MIT for the University of Toronto/CITA effective September 1, 2026, so any postdoc search should confirm her host institution directly.

Techniques:
Department(s)/lab(s): Astronomy | Shen Group @ UIUC
Summary:

Studies quasars and supermassive black hole growth via reverberation mapping and large time-domain spectroscopic/photometric surveys.

Department(s)/lab(s): Physics | Simcoe Group: Extragalactic Observations and Instrumentation @ MIT
Summary:

NON-PREFERRED (astronomy pivot, kept for review). Simcoe designs and builds custom cryogenic infrared spectrographs (FIRE, and the new fiber-fed LLAMAS integral-field spectrograph) for the Magellan telescopes to study the chemistry of galaxies and quasars in the first billion years after the Big Bang; this is an instrumentation-driven astro program rather than a quantum-sensor program per se, so it is included as a borderline pivot.

Techniques:
Department(s)/lab(s): Astronomy / Physics | Soares-Furtado Group (Stellar & Exoplanet Astrophysics) @ UWMadison
Summary:

Observational astrophysicist studying the formation and evolution of stars and their planets, combining Kepler/K2, TESS, JWST, and Gaia data to detect young exoplanets and identify signatures of planetary engulfment by host stars.

Department(s)/lab(s): Physics (Cavendish Laboratory) / Kavli Institute for Cosmology | Tacchella Group @ Cambridge
Summary:

Tacchella studies the physics of galaxy and black hole formation and evolution across cosmic time, combining analytical and cosmological models with cutting-edge multi-wavelength data, and plays a leading role in JWST/NIRCam observations characterising the earliest galaxies.

Department(s)/lab(s): School of Physics | Tinney Exoplanetary Science Group @ UNSW
Summary:

Tinney is an exoplanet hunter who builds the spectrographs he uses. He leads Veloce, the high-resolution, ultra-stable echelle spectrograph on the Anglo-Australian Telescope, whose entire purpose is to measure stellar radial velocities at the ~1 m/s level — a fractional wavelength shift of order 10^-9 — which requires obsessive control of thermal, mechanical and illumination systematics plus laser-comb or etalon wavelength calibration. He also works on brown dwarfs and on disentangling stellar activity from planetary signals. 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 — precision radial velocity is a frequency-metrology problem dressed as astronomy: like a pT/sqrt(Hz) magnetometer, the instrument's raw sensitivity was solved years ago and all remaining progress is in systematics and calibration. Good pivot target for a metrology-trained candidate.

Techniques:
Department(s)/lab(s): Astronomy | Tremonti Group @ UWMadison
Summary:

Observational astronomer studying galaxy evolution and the processes (feedback, galactic winds) that regulate star formation in massive galaxies, using UV-to-IR spectroscopy and SDSS data.
