NON-PREFERRED (borderline precision-measurement pivot, kept for review). Garcia Ruiz develops precision laser spectroscopy of atoms and molecules built from short-lived radioactive nuclei (at CERN-ISOLDE and the new FRIB facility) to measure nuclear charge radii, moments, and to search for symmetry-violating effects (parity/time-reversal violation) analogous to eEDM searches; it is fundamental precision measurement rather than a deployable quantum sensor, but shares techniques and motivation with the eEDM/precision-AMO quantum-sensing cluster.
Gardner's group develops infrared and Raman microspectroscopy for biomedical diagnostics and disease sensing. Research directions: (1) FTIR synchrotron microspectroscopy — using Diamond Light Source synchrotron IR beam for high-spatial-resolution chemical mapping of biological tissues for cancer diagnosis; (2) Raman microspectroscopy — label-free chemical imaging of cells and tissue for disease classification using machine-learning chemometrics; (3) SERS probes — developing gold nanoparticle SERS labels for targeted cancer biomarker detection; (4) Breathomics — on-chip photonic sensors for exhaled breath analysis for early disease detection. The infrared and Raman methods provide label-free molecular sensing with potential for quantum-enhanced sensitivity.
Garner uses high-resolution, single-molecule tracking and localization microscopy (PALM-based) to study the dynamic spatial organization of the bacterial cytoskeleton and cell-wall synthesis machinery in live prokaryotic cells at nanometer precision.
Garrido is a computational cognitive neuroscientist — predictive coding, Bayesian brain models, neuroimaging biomarkers for mental health — who was appointed a chief investigator of the ARC Centre of Excellence in Quantum Biotechnology specifically to work with the Melbourne and UQ physics groups on non-invasive quantum-sensor recording of human brain magnetic fields. She is the human-subject and source-reconstruction end of the QUBIC portable-brain-imager programme: her lab supplies the paradigms, the clinical cohorts and the inverse-problem modelling that a diamond- or OPM-based MEG system has to serve. 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 — she is not a sensor developer, but she is the reason the pT/sqrt(Hz)-class magnetometers being built at Melbourne have a human-trials pathway at all. Preferred attributes present in strength: bioelectromagnetism and human trials with novel quantum technologies. Included as a deliberate borderline case — a sensing postdoc would be the physics half of a collaboration with this lab, not a member of it.

Prof. Gaynor (Chemistry, joined summer 2023) develops cutting-edge ultrafast spectroscopy at the physics-chemistry frontier. Directions: (1) Attochemistry — new ultrafast laser spectroscopies operating on attosecond to femtosecond timescales to directly measure how electron spin and orbital motion couple to molecular geometry (spin-vibronic coupling) in chiral molecules and materials of interest for energy conversion and spintronics; (2) Multidimensional nonlinear spectroscopy (2D electronic spectroscopy, 2D vibrational) to track energy and charge transfer immediately after photoexcitation; (3) Instrumentation-first approach: building novel attosecond transient absorption and correlation spectroscopy apparatus from scratch, enabling entirely new observables (e.g., electron-nuclear and spin-orbital correlations).

Hylkje Geertsema uses single-molecule super-resolution fluorescence microscopy (TIRF, SMLM, PALM/STORM) to study DNA replication dynamics. Her lab visualises and quantifies individual replication proteins at replication forks in living cells to understand the kinetics and fidelity of DNA copying. Research focuses on measuring spatiotemporal dynamics of protein assemblies during DNA metabolism with nanometre resolution.

Key thrusts: (1) Optically-trapped levitated dielectric nanospheres and microspheres achieving zeptonewton (10⁻²¹ N) force sensitivity, applied to probing short-range deviations from Newtonian gravity at micrometer scales; (2) ARIADNE, an international NMR-based experiment using superfluid ³He to search for the QCD axion via axion-mediated spin-dependent forces between a rotating mass and polarized nuclei; (3) Collaboration on MAGIS-100, the 100 m-tall atom interferometer at Fermilab for gravitational wave detection in the mid-band (0.3–10 Hz) and ultralight dark matter searches; (4) Cryogenic optical cavity dark matter comparisons with Gabrielse and Kovachy groups.
