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.

Cotter leads the Quantum Navigation research stream at Imperial's Centre for Cold Matter. He develops compact, fieldable cold-atom inertial sensors for GPS-denied navigation. Milestones: first demonstration of a cold-atom accelerometer on the London Underground (measuring acceleration/vibration in a real transit environment); successful field trials of quantum inertial sensors aboard the Royal Navy research ship XV Patrick Blackett (2023); Arctic field trials with Royal Navy (2025). His sensors use magnetically launched cold-atom Rb clouds and simultaneous multi-axis interferometry. He also contributes to AION-related atom interferometry work and the Quantum Technology Hub in Sensors and Timing. Department of Materials cross-appointment.

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.

French is Professor and former Head of the Photonics Group (2001–2013). His group at Imperial (with Dunsby and Neil) develops multidimensional fluorescence imaging technology for life sciences and clinical applications. Research portfolio: (1) FLIM — wide-field time-gated FLIM using gated optical intensifiers and TCSPC for single-cell FRET-based biosensing of protein-protein interactions, cell signalling (kinase activity), and drug-target engagement in multi-well plates; (2) Super-resolved microscopy — STED, easySTORM (lower-cost STORM), and SIM+FLIM for mapping molecular function to biological nanostructure below the diffraction limit; (3) FLIM endoscopy — flexible wide-field FLIM endoscopes for label-free cancer diagnostics (autofluorescence lifetime) and osteoarthritis cartilage; (4) Open-source imaging — automated multiwell plate FLIM reader for high-content drug screening.

Lim is an Advanced Research Fellow jointly responsible for the ultracold eEDM experiment at Imperial. He contributed to demonstrating sub-Doppler laser cooling of YbF to 100 μK (PRL 2018), the first demonstration of laser cooling of a heavy polar molecule to ultracold temperatures. He now leads development of the lattice eEDM experiment, developing techniques for loading laser-cooled YbF into a 3D optical lattice for precision eEDM measurements with coherence times far exceeding those of the beam experiment.

Sauer co-leads both YbF eEDM experiments at the Centre for Cold Matter together with Tarbutt and Lim. Key contributions: magnetometry for EDM measurement (design and characterisation of precision magnetic field systems for the ultracold eEDM experiment), precision spectroscopy of heavy polar molecules (YbF, lattice eEDM), and development of spin polarisation/analysis schemes. Co-PI on STFC grants for eEDM and magnetometry. Together the group aims to probe the eEDM at the 10^−30 e·cm level — several orders of magnitude improvement over existing measurements from ACME (Harvard/Yale).

Tarbutt co-leads the Imperial eEDM experiment using YbF molecules and runs an independent molecular array quantum computing/sensing programme. Two parallel eEDM experiments: (1) Ultracold YbF beam — 2D transverse laser cooling producing 200 μK, 2×10^5 molecules/shot, eEDM sensitivity of 1.8×10^−28 e·cm/day (near shot-noise limit); (2) YbF 3D optical lattice — aiming for 10^−30 e·cm/year, requires laser cooling to μK and loading into 3D optical lattice, using novel all-optical spin polarisation and analysis. Also leads UKRI project on testing fundamental physics using arrays of ultracold molecules (CaF in optical tweezers for two-qubit molecular gates). These experiments probe CP-violation and BSM physics at PeV energy scales through precision molecular spectroscopy.

Thompson leads the Ion Trapping Group at Imperial using RF (Paul) traps with laser-cooled Ca-40 ions and Penning traps. Research foci: (1) High-fidelity quantum logic gates — optimal control techniques for single-ion state manipulation and two-qubit gates; demonstrated >1 s coherence times via Ramsey interferometry in a Penning trap; (2) Precision spectroscopy — ytterbium ion optical clock uncertainty characterisation at 2.2×10^−18 fractional uncertainty (NPL collaboration); proposed precision laser spectrometer for highly charged ions (HCI) in cylindrical Penning traps for QED tests; (3) Axion sensing — collaborating with Devlin on the Penning-trap single-electron photon counter for axion searches; (4) Coulomb crystals — ultrahigh resolution spectroscopy of ion crystals. Past work includes SPECTRAP project at GSI Darmstadt for HCI spectroscopy.

Truppe is an Associate Professor at the Centre for Cold Matter, specialising in laser cooling of atoms and diatomic molecules using deep-UV lasers. His current focus is aluminium monofluoride (AlF) and magnesium fluoride (MgF): AlF can be produced in a bright cryogenic buffer-gas beam and rapidly optically cycled on the A¹Π↔X¹Σ⁺ transition, making it a candidate for high-density laser trapping; MgF is characterised for its A²Π↔X²Σ⁺ hyperfine structure, relevant to laser cooling. These molecules open routes to ultracold chemistry studies, precision spectroscopy, and quantum simulation. Truppe returned to Imperial as faculty after a period at the Fritz Haber Institute (ERC Starting Grant, 'CoMoFun', cold molecules for fundamental physics).
