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.
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.
Gigan leads the Optical Imaging group at LKB, pioneering wavefront shaping and computational imaging through scattering media. Research directions: (1) Wavefront shaping / transmission matrix — measuring the ~10^5 optical modes of a scattering sample's transmission matrix to focus and image through highly scattering biological tissues; roadmap on deep tissue imaging (J. Phys. Photonics 2022, lead author); (2) Multimode quantum optics through complex media — spatially multimode squeezed states transmitted through scattering media for quantum-enhanced imaging; (3) Optical computing / AI — using multiple scattering as a physical neural network for reservoir computing and nonlinear machine learning (LightOn spin-off, 2016); (4) Neurophotonics applications — focusing through the skull for deep brain imaging. Two ERC grants (2011, 2017). Optica Fellow. IUF member (2016–2021).
Sylvain Gigan's PICO (Photonics, Information, and Complexity) group focuses on imaging through and with complex and scattering media. Research: (1) wavefront shaping through scattering media — adaptive optics and transmission matrix approaches for deep-tissue fluorescence imaging; (2) multimode quantum optics through complex media — pushing quantum light through scattering and multi-mode fibres; (3) analogue computing with random optical scattering media.

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 — the emphasis is on extracting nanoscale structural information from photon statistics rather than on brute-force localisation — 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 — DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity — 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.

Imaging technique innovations: (1) Oblique plane illumination (OPI / scanned oblique plane illumination, SOPi) microscopy — a single-objective light-sheet technique achieving tilt-invariant volumetric imaging for rapid 3D capture of fluorescently labeled neural structures without mechanical tilting; (2) Two-photon fluorescence imaging and two-photon glutamate/neuromodulator photorelease for single-synapse resolution in live tissue; (3) Near-infrared genetically-encoded calcium indicators (with Verkhusha group) for in vivo multi-color neural recording with reduced photobleaching. The lab's technical contributions are centered on extending the spatial and volumetric resolution of live-tissue fluorescence imaging. Irving M.
