Miller develops nitrogen-vacancy nanodiamond quantum biosensors for rapid diagnostics, controlling the NV spin state with resonant green/microwave illumination to frequency-separate fluorescence signal from background and achieve single-molecule detection of nucleic acids (e.g. HIV RNA with a short isothermal amplification step) in lateral-flow and widefield formats. His current projects span nanodiamond sensors for point-of-care disease diagnostics, quantum sensing at neural-interface implants, and wide-field quantum sensing of large randomly-oriented nanodiamond ensembles in biological samples, actively recruiting PhD students through the Q-BIOMED hub.

Natrajan's group develops luminescent lanthanide complexes for chemical and biological sensing. Research directions: (1) Time-gated lanthanide luminescence sensing — long-lifetime Eu3+, Tb3+, and Yb3+ complexes with millisecond emission lifetimes for background-free sensing in cells and tissue; (2) Intracellular sensing — luminescent probes for sensing O2, pH, viscosity, and specific enzymes inside living cells with spatiotemporal resolution; (3) Chiral discrimination — circularly polarized luminescence (CPL) from Eu3+ complexes for enantioselective sensing; (4) Responsive probes — switchable lanthanide complexes as ratiometric sensors for biomedical imaging. The long-lifetime emission enables time-gating strategies analogous to quantum sensing protocols.

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.

Treussart uses fluorescent nanodiamonds (NV centres) as photostable bio-probes: intracellular single-particle tracking, nanoscale thermometry/magnetometry, and multimodal biosensing in cells and organisms, alongside super-resolution imaging - a direct NV-ensemble-to-biology bridge. In the broader landscape of NV-centre ensemble quantum sensing (DEER, nano-NMR, T1 relaxometry) operating near pT/sqrt(Hz) sensitivity, this work is applied here to living cells via nanodiamond probes.
