Akerib is a leader of the LZ (LUX-ZEPLIN) dark matter experiment, a dual-phase liquid-xenon time-projection chamber that uses single-photon and single-electron-sensitive detection to search for weakly interacting massive particles.
Araujo is a long-standing leader of the LZ (LUX-ZEPLIN) liquid-xenon dark matter experiment at SURF, working on detector design, calibration and background rejection for direct-detection WIMP searches, and previously ZEPLIN. His group also contributes to future noble-liquid detector R&D.
Buchmueller is the lead PI of the AION consortium (~£10M funded by UKRI/STFC), leading Imperial's ultracold strontium lab developing single-photon large-momentum-transfer atom interferometry on the Sr clock transition. Key achievements: prototype Sr differential atom interferometer operating at the Standard Quantum Limit with laser noise rejection demonstrated (arXiv 2504.09158, Apr 2025); AION-10 technical design report published (Aug 2025). Buchmueller also leads the AEDGE space mission concept for the European Space Agency, seeking to deploy a km-scale Sr atom interferometer in space for dark matter and mid-frequency gravitational wave detection. Deeply involved in MAGIS-100 partnership (Fermilab) and Cold Atoms in Space community building with 130+ proponents. Active in CMS Collaboration at CERN.
Chaudhuri leads the Princeton Axion Search (PXS) and is a core contributor to the DMRadio program, using solenoidal lumped-element LC resonators, DC-SQUID and near-quantum-limited (traveling-wave parametric amplifier) readout to search for QCD axion dark matter from roughly neV to ueV masses; his group explicitly frames this as electromagnetic quantum sensing beyond the Standard Quantum Limit. He is actively developing superconducting resonators and RF quantum upconverters that push readout sensitivity toward and below the SQL.

Devlin is a Royal Society URF at the Centre for Cold Matter building a new experiment to detect axion and dark matter particles. His prior work at CERN's BASE collaboration (Penning trap antiproton experiment) used the ultra-sensitive superconducting detection circuit of a cryogenic Penning trap to set new constraints on axion-like particle couplings to photons (~2.79 neV/c² range; PRL 2021). At Imperial he is developing a Penning trap single-photon counter concept using a single trapped electron to detect 30–60 GHz photons from axion-photon conversion in a strong magnetic field (arXiv 2601.05472, March 2026), targeting axion masses of 124–248 μeV. This approach could overcome the standard quantum noise limit that hampers conventional haloscope searches at high mass. Active PDRA posting open May 2025.
Prof. Figueroa-Feliciano leads Northwestern's experimental program in quantum sensing for particle physics. Key directions: (1) SuperCDMS SNOLAB — Northwestern's NU's role in the Super Cryogenic Dark Matter Search at SNOLAB (2 km underground in Canada), using ultra-pure Si and Ge crystals with superconducting TES sensors to detect low-mass dark matter (particles below the proton mass); in March 2026 the experiment reached operating temperature (<10 mK), transitioning to detector calibration for the first ever dark matter search at the site; (2) NEXUS facility at Fermilab: Northwestern-built test facility led by Figueroa-Feliciano for SuperCDMS detector calibration and for measuring how ionizing radiation affects superconducting qubits (published fall 2025); (3) Qubit-based quantum sensing: developing HVeV R&D devices with <1 eV resolution and qubit parity-detection techniques for eV-scale and sub-eV dark matter detection. Associate Vice President for Research at Northwestern; INQUIRE Executive Committee. Joint appointment at Fermilab.
Flambaum is one of the most cited atomic theorists alive and the intellectual source of a large fraction of the modern precision-AMO new-physics programme. His group computes the atomic and molecular structure factors that convert an experimental frequency shift into a bound on new physics: enhancement factors for electron and nuclear EDMs, atomic parity violation, the sensitivity of clock transitions to variation of the fine-structure constant, and — most relevant to quantum sensing — the response of atomic clocks, magnetometers and comagnetometers to ultralight/axion-like dark matter fields. He proposed much of the theory behind using networks of quantum sensors as dark matter detectors. 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 — his theory is what tells an experimentalist what a pT/sqrt(Hz) magnetometer or a 10^-18 clock actually constrains: without it, a spin-precession measurement is just a number. Theory group; a sensing postdoc would collaborate rather than join.
Fruth is an experimentalist on LZ, the world-leading liquid-xenon dark matter experiment, and works on the detector-physics end: electron and single-photon backgrounds, calibration, and the characterisation of the anomalous low-energy events that currently limit sensitivity at the bottom of the energy spectrum. The programme is a pure exercise in pushing a detector's noise floor down until it is limited by irreducible physics (the neutrino fog). 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 — dark matter detection and NV-ensemble magnetometry are the same problem in different clothing — an exquisitely quiet detector, a signal below the background, and a systematics budget that determines everything — and the quantum-sensing community is increasingly supplying the readout technology (quantum-limited amplifiers, single-photon counters) that these experiments now need. Early-career PI.
