Otte's group pioneered electron-spin-resonance scanning tunneling microscopy (ESR-STM), positioning individual atoms one-by-one with a low-temperature STM tip and using all-electrical RF driving to coherently control and single-shot read out individual electron and nuclear spins (e.g., single 49Ti nuclei) with sub-neV energy resolution and atomic spatial resolution. Where NV-ensemble sensing reaches pT/sqrt(Hz) at the nanoscale, Otte's ESR-STM instead reaches the ultimate single-atom limit of magnetic sensing and quantum control, and the lab is developing a next-generation 15 T / 20 mK STM to push coherence times and energy resolution further.

Renaud develops nonlinear and single-sided ultrasound methods to characterize bone and vascular tissue in vivo — quantifying cortical bone porosity, blood-flow, and microbubble/microcrack acoustic signatures — and collaborates closely with David Maresca's functional-ultrasound group on transcranial aberration-corrected Doppler imaging of the brain. This acoustic biosensing work extends the lab's push toward higher-sensitivity, non-invasive acoustic biomarkers analogous in spirit to other quantum-adjacent biosensing modalities.

Toeno van der Sar's group uses NV-centre diamond magnetometry to study correlated spin dynamics and electric currents in magnetic and 2D materials. Research directions: (1) scanning NV magnetometry of topological magnets, 2D magnetic materials (CrI3, Fe3GeTe2), and superconductors; (2) spin-wave (magnon) spectroscopy in magnetic thin films using NV sensors; (3) widefield NV imaging of biological samples and materials. The group develops both NV scanning probes and widefield NV ensembles for nanoscale spatial mapping of magnetic phenomena.

Varnavides leads the Curious Beams Lab, using scanning transmission electron microscopy, 4D-STEM/electron ptychography, and computational phase-retrieval to obtain atomic-resolution, three-dimensional maps of electrostatic and magnetic order (e.g., antiferromagnetic textures, charge/heat/spin transport) in quantum materials — a solid-state, electron-beam analogue to optical quantum-material imaging that similarly pushes spatial resolution past conventional limits. He joined TU Delft ImPhys as Assistant Professor in 2025 after a Miller Fellowship at UC Berkeley and is building out instrumentation for functional imaging of both materials and biological systems.

Weingärtner's Magnetic Resonance Systems (Mars) Lab develops new MRI signal models and pulse sequences to non-invasively resolve the brain and heart microvasculature down to the capillary scale, using hydrogen nuclei as 'microscopic spies' on their surrounding tissue microstructure; the work is validated with in-vivo human studies (e.g., microvascular disease, cardiac imaging) and supported by an ERC Starting Grant. The lab is actively recruiting PhD students/postdocs to push quantitative MRI biomarkers into new disease areas.
