Bean's group designed, built, and operates MAROON-X, a fiber-fed, high-dispersion precision radial-velocity spectrograph on the 8m Gemini-North telescope, achieving sub-m/s-class radial-velocity precision to detect and mass-characterize small planets around nearby M dwarfs and to identify/refine targets for JWST atmospheric spectroscopy. This is an astronomy pivot from quantum sensing in the sense the filter intends: a purpose-built, cutting-edge-sensitivity spectrograph (rather than a quantum sensor per se) enabling detection at the edge of instrumental precision.
Observational exoplanet astronomer using ground- and space-based facilities (including HST and JWST) to characterize exoplanet atmospheres and compositions.
Studies planetary dynamics and exoplanetary system architectures, combining theoretical dynamical modeling with observational discovery of exoplanets; 2026 AAS DDA Vera Rubin Early Career Prize recipient.
Birkby uses the world's largest telescopes and highest-resolution spectrographs to determine the composition and dynamics of exoplanet atmospheres via high-resolution cross-correlation spectroscopy, as ERC Starting Grant PI of the 'exoZoo' project, with a longer-term goal of surveying nearby terrestrial exoplanets with future Extremely Large Telescopes.
Observational exoplanet astronomer studying planetary system architectures and demographics using transit and radial-velocity surveys.
Madhusudhan pioneered inverse 'atmospheric retrieval' techniques to determine the chemical composition, interior structure and formation history of exoplanets from their spectra, including recent JWST-based investigations of potential biosignature gases on temperate sub-Neptunes (Hycean worlds).
Queloz (2019 Nobel Prize, co-discoverer of 51 Peg b) leads exoplanet research at Cambridge, including precision radial velocity spectrograph development and transit photometry. He chairs the CHEOPS space mission science team and is founding director of the Leverhulme Centre for Life in the Universe at Cambridge. Research focuses on characterizing transiting terrestrial planets (especially around M dwarfs including TRAPPIST-1) and atmospheric biosignature detection with JWST-era instruments. Part-time appointment at University of Geneva.
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.
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.
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.
