Ananthanarayanan was awarded the Royal Microscopical Society Life Sciences Award in 2025 for the use of novel microscopies in cell biology. Her group images individual motor proteins — dynein, kinesin — and the mitochondria they transport, in living cells, at single-molecule sensitivity, combining light-sheet and TIRF-class imaging with particle tracking to ask how organelle positioning and mitochondrial dynamics are controlled. The methodological emphasis is on getting single-molecule sensitivity inside a live cell rather than in vitro, which is the hard version of the problem. 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 closest thing at UNSW to a biological end-user for an in-cell quantum sensor: the mitochondrial systems she studies are precisely where NV nanodiamond thermometry and free-radical relaxometry at pT/sqrt(Hz) have been aimed, and she has the live-cell imaging infrastructure to validate any such measurement independently.

Ashley builds instruments that must work unattended in the worst environment on Earth: the PLATO and related autonomous observatories on the Antarctic plateau (Dome A/C), where he characterised the site's exceptional infrared background, seeing and atmospheric stability, and built the power, thermal and control systems needed for a telescope to survive a polar winter with no human present. He also works on low-noise infrared detectors and on CubeSat instrumentation. 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 discipline here — making a low-noise detector work reliably outside a controlled laboratory, with a hard power and thermal budget — is the same one that separates a benchtop pT/sqrt(Hz) magnetometer from a deployable one, and it is a skill set the quantum sensing field is short of. Borderline inclusion under the astronomy criterion; kept because the sensor and its environment are the entire object of study.

Barry works on the detection of the 21-cm signal from the Epoch of Reionisation with the Murchison Widefield Array and, prospectively, SKA-Low. Her specialty is calibration systematics: she has shown how small errors in the sky and beam model propagate into spectral structure that mimics or swamps the cosmological signal, and has developed the diagnostic and mitigation framework that current MWA upper limits rest on. This is a measurement whose entire difficulty is instrumental. 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 intellectual structure is identical to a hard magnetometry measurement: raw sensitivity is adequate, and everything depends on understanding correlated, instrument-induced systematics well enough to subtract them below the signal. Early-career PI (DECRA). Borderline astronomy inclusion, kept on the systematics/instrument criterion.

Berengut works on the atomic structure theory underpinning next-generation clocks: highly charged ions, whose optical transitions are both extremely narrow and exceptionally sensitive to variation of fundamental constants and to new physics, and the thorium-229 nuclear clock. He identifies which ionic species and transitions maximise sensitivity to the physics of interest while remaining experimentally accessible, and computes the many-body structure needed to interpret them — work that has directly guided the experimental HCI clock programmes at PTB, MPIK and NIST. 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 — clocks and magnetometers are the two great classes of quantum sensor; his work is on the frequency side of the same estimation problem that fixes pT/sqrt(Hz) performance on the magnetic side. Theory PI with close experimental collaborations.

Boecking leads the Molecular Machines Group and is acting director of the EMBL Australia Node in Single Molecule Science. The group reconstitutes molecular machines — clathrin coat disassembly, HIV capsid assembly and uncoating, pore-forming toxins — and watches them work one molecule at a time by TIRF, interferometric scattering (mass photometry) and fluorescence fluctuation methods, resolving short-lived intermediates that ensemble kinetics averages into invisibility. He trained originally in surface chemistry and biosensors with Gooding, which gives the group unusual competence in engineering the surfaces these assays run on. 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 argument for single-molecule methods over ensemble ones is identical to the argument for pushing NV sensing below its pT/sqrt(Hz) ensemble regime: the interesting biology lives in heterogeneity and in transient states that averaging destroys. Strong methodological neighbour for a quantum-biosensing candidate.

Cassidy (formerly Microsoft/Sydney) builds hybrid superconductor-semiconductor quantum devices and the microwave measurement chains needed to read them out: dispersive gate sensing, superconducting resonators coupled to semiconductor nanostructures, and quantum-limited parametric amplification. The programme sits at the boundary between quantum computing hardware and quantum sensing — many of the same circuits used to read a qubit are, viewed differently, near-quantum-limited detectors of microwave photons or of charge. 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 — a superconducting-resonator readout chain with a quantum-limited amplifier is the leading route to inductively-detected spin resonance at sensitivities well below the pT/sqrt(Hz) regime accessible to optical NV ensembles, and Cassidy's group has the full stack of skills required. Mid-career, actively building; good autonomy for a postdoc.

Curmi is a structural and single-molecule biophysicist whose most-cited work is on the light-harvesting antenna proteins of cryptophyte algae, where he and collaborators reported long-lived electronic coherence at ambient temperature — one of the founding results of the quantum-biology field and still one of its most argued-over. His group determines the structures of these antenna complexes and engineers them, and separately works on protein-based molecular motors and on single-molecule fluorescence and FRET measurements of conformational dynamics. 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 — Curmi supplies the biological systems in which quantum coherence is actually claimed to matter; a pT/sqrt(Hz)-class spin sensor capable of watching radical-pair or exciton dynamics in situ would be aimed at exactly the questions his structures raise. Preferred attribute present: genuine quantum-biology substrate rather than a quantum-flavoured metaphor.

Dzurak leads the silicon CMOS quantum dot spin qubit programme at UNSW and co-founded Diraq, the company commercialising it. The group demonstrated the first silicon MOS qubit, two-qubit logic in silicon, and has pushed toward fidelities above the fault-tolerance threshold in industrially-manufactured CMOS devices, including work on gate-stack engineering for low charge noise and on single-electron-transistor charge sensing for readout. 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 relevant transferable asset is the readout: the single-electron-transistor and gate-based dispersive sensors this group builds are among the most sensitive electrometers in existence, the charge-domain analogue of pT/sqrt(Hz) magnetometry. Caveat against the stated preference: the programme is now heavily fabrication- and yield-driven and closely tied to a commercial roadmap, so a sensing-focused postdoc would be somewhat off the group's main axis.

Flambaum is one of the most cited atomic theorists alive and the intellectual source of a large fraction of the modern precision-AMO new-physics programme. His group computes the atomic and molecular structure factors that convert an experimental frequency shift into a bound on new physics: enhancement factors for electron and nuclear EDMs, atomic parity violation, the sensitivity of clock transitions to variation of the fine-structure constant, and — most relevant to quantum sensing — the response of atomic clocks, magnetometers and comagnetometers to ultralight/axion-like dark matter fields. He proposed much of the theory behind using networks of quantum sensors as dark matter detectors. 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 — his theory is what tells an experimentalist what a pT/sqrt(Hz) magnetometer or a 10^-18 clock actually constrains: without it, a spin-precession measurement is just a number. Theory group; a sensing postdoc would collaborate rather than join.

Gambin was the first EMBL Australia group leader appointed to Single Molecule Science. His signature method combines cell-free protein expression with two-colour single-molecule coincidence and fluctuation spectroscopy, which sidesteps purification entirely: proteins are expressed, labelled and measured in lysate, an order of magnitude faster than conventional interaction assays. The biology is protein self-association and aggregation — alpha-synuclein in Parkinson's, cardiac and muscular disease proteins — where the size distribution of oligomers, not the mean, is the quantity of interest. 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 conceptual overlap with quantum biosensing is the insistence on distributions over averages, and his aggregation systems (paramagnetic-species-generating, redox-active amyloid) are a plausible target for T1-relaxometry-based NV detection at pT/sqrt(Hz) in the near term.
