Observational cosmologist working on the Dark Energy Survey and the Vera C. Rubin Observatory/LSST, using wide-field optical imaging to study dark energy, dark matter, and dwarf galaxies; involved in survey instrumentation and analysis pipelines.
Builds astronomical spectroscopic instrumentation and studies galaxy structure, dynamics, and evolution via integral field spectroscopy (e.g., SDSS-IV MaNGA); leads WIYN telescope instrumentation efforts.
Bland-Hawthorn founded the field of astrophotonics and directs SAIL. The core idea is to replace bulk-optic astronomical instruments with single-mode photonic devices: the photonic lantern (an adiabatic multimode-to-single-mode transition that lets a seeing-limited telescope beam be fed into single-mode circuitry), fibre Bragg grating OH-suppression filters that notch out the ~100 atmospheric emission lines swamping the near-infrared, integral-field hexabundles, photonic combs and integrated spectrographs. He also leads Galactic archaeology work (GALAH, S5). 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 — SAIL is where a quantum-sensing physicist's instincts about single-mode optics, photon budgets and noise floors transfer most directly into astronomy — the entire discipline exists because photon-starved measurements need front-end optics designed at the fundamental limit, exactly as with pT/sqrt(Hz) magnetometry. Excellent pivot target; large group, deep fabrication resources.
Bryant invented the hexabundle — a lightly-fused bundle of optical fibres that behaves as an imaging integral-field unit while retaining high throughput — and leads the Hector galaxy survey instrument built around them. Her work is squarely instrumentation: fibre bundle design and fabrication, throughput and cross-talk characterisation, and the deployment of hundreds of these units on a telescope to obtain spatially resolved spectroscopy of thousands of galaxies. 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 — the connection is device-level rather than conceptual, but the discipline — squeezing every photon out of a fibre-coupled optical train — is the same one that governs collection-efficiency-limited pT/sqrt(Hz) NV ensemble readout. Borderline inclusion under the astronomy criterion; kept because the sensor front end is the object of study.
Leon-Saval co-invented the photonic lantern and is the fibre-device engineer of the SAIL programme. His group designs, draws and characterises multicore fibres, mode-selective lanterns, OH-suppression fibre Bragg gratings and hexabundles, and increasingly applies the same devices outside astronomy — in telecommunications space-division multiplexing and in medical endoscopy and imaging through fibre. The unifying technical problem is coupling a spatially-incoherent, aberrated beam into single-mode circuitry without losing photons. 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 — photonic lanterns are directly applicable to quantum sensing readout: the same device that feeds a seeing-limited telescope beam into a single-mode spectrograph can feed fluorescence from a scattering biological sample into a single-mode quantum-limited detector, preserving the photon budget that a pT/sqrt(Hz) NV measurement depends on.
Parry designs and builds multi-object and integral-field near-infrared spectrographs for ground-based telescopes (CIRPASS, SMIRFS, MOONS) and is currently developing concepts for unfolding space telescopes and instruments to search for exoplanet biosignatures.
The Stern Group explores fundamental quantum interactions of photons with 2D materials, nano-scale structures, and atoms. Key thrusts: (1) Valley-selective exciton-polaritons in monolayer transition-metal dichalcogenides (MoS₂, MoSe₂, WSe₂) embedded in optical microcavities — hybrid light-matter quasiparticles with valley-selective polarization and cavity-modified dynamics; (2) 2D semiconductor quantum emitters — quantum-dot-like single-photon emitters formed by confinement in TMD nanoribbons and by chemical functionalization/strain engineering of defects; (3) Astrophotonics: collaboration with Argonne National Laboratory and the Australian Astronomical Observatory to design and fabricate silicon ring-resonator photonic circuits for OH sky-background suppression in near-IR astronomical spectrographs; (4) Quantum non-reciprocal photonics in axisymmetric microresonators. Experimental tools: time-resolved spectroscopy, single-photon counting, nanofabrication. DOE Early Career Award; ONR Young Investigator Award; Sloan Research Fellow 2013. Affiliated with Fermilab-Northwestern CAPST.
Tuthill is the world's leading practitioner of aperture-masking interferometry and its modern photonic successors. His group's instruments — GLINT (a photonic nuller that destructively interferes starlight on a chip), Dragonfly, and the kernel-phase analysis framework — exist to recover structure at and below the formal diffraction limit of the telescope, in the photon-starved, speckle-dominated regime where naive imaging fails. Science targets are the dusty pinwheel nebulae of Wolf-Rayet binaries, protoplanetary discs and direct detection of exoplanets. 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 astronomy entry in the search that most closely mirrors the intellectual structure of quantum sensing: the instrument's performance is set by a fundamental noise floor (photon and speckle noise, analogous to the shot-noise floor at pT/sqrt(Hz)), and the entire game is designing an estimator and a hardware front end that saturate it. Preferred attribute strongly present.
