Gureyev is one of the originators of propagation-based X-ray phase-contrast imaging and the transport-of-intensity phase-retrieval methods that made it practical; his current work concerns the information-theoretic limits of imaging โ how signal-to-noise, spatial resolution and radiation dose trade against one another โ and the application of those limits to phase-contrast tomography, ptychography and electron microscopy, including biomedical imaging at clinically tolerable dose. Positioned against the established body of NV-ensemble quantum sensing work โ DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity โ the shared intellectual core is the noise-resolution-dose triangle: the same estimation-theory framework that sets the pT/sqrt(Hz) floor of an NV ensemble governs how many photons a phase-contrast image needs. Borderline inclusion (X-ray rather than quantum sensing), kept because the technique is explicitly about pushing resolution past conventional limits.
Ham's group builds CMOS integrated-circuit platforms spanning scalable, chip-based NMR spectrometers (including impedance-tuned microwave loops for controlling dense NV-diamond spin ensembles, developed with Ronald Walsworth) and CMOS intracellular microelectrode arrays that record from thousands of neurons in parallel โ a dual quantum-sensing/bioelectronic-sensing program built around scaling sensitive spin- and electrode-based sensors onto integrated circuits.
Develops microfluidics and imaging-based spatial-omics technologies for high-resolution, high-throughput assays and modeling of complex biological systems, including bottom-up construction of synthetic cells.

Hinde is a fluorescence-fluctuation physicist embedded in cell biology: she uses pair-correlation function analysis, number-and-brightness, phasor-FLIM and FRET to read out chromatin compaction, protein-chromatin binding dynamics and nucleocytoplasmic transport in living nuclei, at spatial and temporal scales that conventional imaging averages away. The programme is a technique-pushing one โ the emphasis is on extracting nanoscale structural information from photon statistics rather than on brute-force localisation โ and it is now being coupled to quantum sensing through her QUBIC investigatorship, where the goal is to combine fluorescence readouts with NV-based magnetic and spin-noise contrast in the same cell. Positioned against the established body of NV-ensemble quantum sensing work โ DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity โ her role in QUBIC is to supply the cell-biological questions and the correlative optical readouts that make pT/sqrt(Hz)-class ensemble sensing biologically interpretable. Preferred attribute present: lifetime- and orientation-resolved methods pushing past the usual resolution limits.

Hutchison works on molecular polaritonics: what happens to chemistry when molecular electronic or vibrational transitions are strongly coupled to a confined optical mode in a Fabry-Perot or plasmonic nanocavity. He was among the first to show that vibrational strong coupling modifies ground-state chemical reactivity, and the group continues to probe polariton-modified energy transfer, photochemistry and transport, alongside single-molecule spectroscopy and 2D-material photonics. Positioned against the established body of NV-ensemble quantum sensing work โ DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity โ the connection to quantum sensing is the cavity: the same Purcell and collective-coupling physics that concentrates optical density of states around a molecule is what is used to improve photon collection and readout fidelity in NV ensembles operating at pT/sqrt(Hz). This is fundamental light-matter physics with a clear nonclassical-state angle.
