Jacques is a pioneer of scanning NV magnetometry, using single nitrogen-vacancy spins in scanning-probe diamond tips to image magnetic textures at the nanoscale under ambient conditions. His team applies this to condensed-matter systems including antiferromagnetic domain walls and chiral spin textures, non-collinear antiferromagnetic order via single-spin relaxometry, and current-driven skyrmion motion in synthetic antiferromagnets, work carried out in close collaboration with materials-physics groups.

Jamieson's group built the counted single-ion implantation capability that underpins every donor spin qubit made at UNSW and Melbourne: individual P, Sb or Bi ions are implanted into silicon through a nanoscale aperture while on-chip detector electrodes register the electron-hole pairs from each ion stop event, so the number and position of dopants is known rather than assumed. Recent directions extend this to high-atomic-number donors for nuclear-spin qudits, to colour-centre creation in diamond and silicon carbide by counted implantation, and to characterising the damage and charge environment those ions leave behind. The work is fabrication-forward but its scientific content is single-particle detection metrology. 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 contribution is upstream: the deterministic creation and validation of the very spin defects whose ensembles are later interrogated by DEER and nanoscale NMR at pT/sqrt(Hz).

Knowles leads the Coherent Quantum Lab at the Cavendish Laboratory. Her research focuses on using NV centers in diamond as quantum sensors to probe matter at the nanoscale in two main thrusts: (1) nanoscale NMR / spin imaging — scanning-probe NV magnetometry of topological and unconventional magnets, Hamiltonian engineering in dense spin ensembles using global dynamical decoupling, and error-correction-enhanced sensor readout; (2) quantum biosensing in living systems — employing diamond nanocrystals functionalized for intracellular delivery to perform simultaneous nanothermometry and nanorheometry in single HeLa cells and C. elegans, using the Q-BiC integrated biocompatible chip platform. She co-leads CANSIS. The lab has a second new instrument running since mid-2025 for biosensing experiments.

Krueger's chemistry group develops diamond and nanodiamond surface chemistry, functionalization and bioconjugation that make NV centres viable, shallow, coherent quantum sensors for chemical and biological targets - the materials-chemistry enabler for NV ensemble sensing. She co-leads Stuttgart's quantum-technologies profile. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work is enabled at the surface-chemistry level by this work.

Lončar's Laboratory for Nanoscale Optics engineers diamond and lithium-niobate nanophotonic devices — including silicon-vacancy (SiV) color-center spin-photon interfaces, entangled quantum memories, and remote entanglement-assisted phase-sensing protocols that beat the standard measurement limit — alongside quantum optomechanical control of single spins via engineered acoustic resonators, directly extending the NV/SiV-diamond quantum-sensing lineage toward chip-integrated, networked quantum-enhanced sensing.

Develops quantum sensing platforms at the biology interface. Core NV-center work: (1) widefield NV magnetic imaging of action potentials in neurons and cardiac tissue; (2) NV-based single-molecule NMR at 14 T resolving molecular structure with single-molecule sensitivity; (3) charge-sensitive shallow NV nanoprobes monitoring real-time cellular electrophysiology; (4) biocompatible diamond surface functionalization enabling multiplexed DNA microarray biosensing; (5) fluorescent-protein spin qubits as biological alternatives to diamond NV (2025 paper, Physics World Top-10 Breakthrough). Runs full NV stack: hot implantation, widefield and confocal ODMR, T1/T2/Hahn echo/DEER/Rabi, automated fitting pipelines. 2026 Sloan Fellow. PhD Lukin/Harvard; postdoc Chu/Stanford. Argonne joint appointment.

McCallum works on the materials and detector physics of donor qubits in silicon and colour centres in diamond and silicon carbide: defect engineering by ion implantation and annealing, characterisation of the resulting spin coherence, and — most relevant to a sensing postdoc — the development of superconducting and semiconductor detectors capable of registering single implanted ions with near-unit efficiency, which is what turns implantation from a statistical process into a deterministic one. He also works on near-surface colour centres, where surface termination and Fermi-level control set the achievable coherence. 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 group supplies the near-surface, coherence-optimised spin ensembles that DEER, nanoscale NMR and T1-relaxometry protocols at pT/sqrt(Hz) sensitivity actually depend on.

Park's group works at the interface of physics, chemistry, and neuroscience, developing nanowire- and nanoelectrode-based intracellular electrophysiology probes as well as NV-diamond quantum sensing platforms (often in collaboration with Lukin), building on the same NV ensemble quantum-sensing lineage (DEER, nanoscale NMR, T1 relaxometry, pT/√Hz sensitivity) while also pushing nanoscale bioelectronic recording.

Prawer is the founding figure of Melbourne diamond science, spanning colour-centre quantum technology, diamond surface chemistry and — unusually — clinical translation. His group developed the nitrogen-doped ultrananocrystalline diamond electrode arrays used in the Australian diamond bionic eye, a hermetically sealed, chronically implantable retinal stimulator that has been through human implantation; that is a rare example of an exotic-materials sensing/stimulation technology carried into human trials. In parallel the group works on diamond surface termination and functionalisation for near-surface NV sensing, nanodiamond bioconjugation, and diamond as a radiation-hard detector material. 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 surface- and materials-engineering work is precisely what sets the standoff distance, and hence the achievable pT/sqrt(Hz) sensitivity, of near-surface NV ensembles used for DEER and nanoscale NMR. Preferred attribute present: demonstrated human trials with a complex implanted technology.

Simpson runs the experimental quantum imaging and sensing laboratory at Melbourne and is the closest match at this institution to a bio-oriented NV sensing postdoc. Two active threads: (i) widefield NV magnetic and spin-relaxation imaging of living cells and tissue, including magnetic imaging of magnetotactic bacteria, cellular free radicals and paramagnetic ion transport, and quantum-probe imaging of neuronal activity; and (ii) engineering Australia's most sensitive diamond vector magnetometer with RMIT and Phasor Innovation, aimed at navigation, underground/undersea sensing and, explicitly, mapping magnetic signals of the human brain in unshielded environments. That second thread is a direct bid at bioelectromagnetism with a quantum sensor. 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 — Simpson's work is a continuation of exactly that lineage, pushing ensemble DEER/T1-relaxometry contrast mechanisms out of the physics lab and into cell biology and human-scale magnetoencephalography. Preferred attributes present: bioelectromagnetism, human-subject ambitions, sensitivity-limited (not fabrication-limited) programme. QUBIC investigator; recruits postdocs regularly.
