Alem develops ruggedised zero-field OPM sensors and turnkey OPM-MEG systems at FieldLine, building on his earlier work developing OPM-MEG at NIST and in Nottingham. His research addresses the robustness, manufacturability and system integration needed to deploy OPM-MEG outside specialised laboratories. He spans sensor development and complete imaging-system design.

Baumgarten develops magnetorelaxometry imaging of magnetic nanoparticles using OPMs, together with biomagnetic source-analysis methods for biomedical sensing. His work focuses on the inverse problems of reconstructing nanoparticle distributions and bioelectromagnetic sources from magnetometer data. He combines instrumentation, modelling and clinical application across sites in Austria and Germany.

Borna builds SERF-OPM based whole-head MEG systems and the associated array electronics at Sandia, and characterises their performance against established SQUID-MEG. His work spans sensor readout, array design and the validation studies that quantify how faithfully OPM systems recover neuromagnetic sources. He focuses on turning OPM sensors into complete, reliable imaging systems.

Bowtell directs the Sir Peter Mansfield Imaging Centre and leads hardware development across biomedical imaging, from ultra-high-field MRI to the magnetic environment that makes wearable OPM-MEG possible. He designs the bi-planar coil systems, matrix gradient and shim sets, and active field-nulling that cancel background fields over the volume in which a subject can move, keeping the residual field low enough for SERF OPMs to operate. His work bridges MRI physics and optically pumped magnetometry, providing much of the field-control engineering underpinning the Nottingham OPM-MEG programme.

Donley develops compact atomic clocks, atom interferometers and vapour-cell atomic sensors at NIST, including microfabricated magnetometers and NMR-on-a-chip. Her work focuses on the atomic physics and engineering needed to make precision instruments small and robust without sacrificing stability or sensitivity. She leads efforts spanning timekeeping, inertial sensing and magnetometry.

Fromhold leads theory and device design for quantum-technology sensors, including cold-atom and atom-chip systems, light-pulse atom interferometry, and models of transport and coherence in trapped atomic gases. His theoretical work supports Nottingham's quantum-enabled magnetometry and gravimetry programmes and informs the design of practical field and inertial sensors. He collaborates closely with the experimental OPM-MEG and cold-atom groups on sensor concepts and system modelling.

Glover works on magnetic-resonance hardware, including RF probe and coil design, field homogeneity, and the assessment of magnetic-field exposure and safety. His coil-design and field-control expertise feeds into the shielding and nulling systems used for OPM-MEG, where precise control of the static and low-frequency field is essential. His research sits at the interface of MRI engineering and the magnetic environment needed for optically pumped magnetometry.

Griffin holds the Rosenberg Chair in Quantum Sensing and leads Strathclyde work on chip-scale and MEMS optically pumped magnetometers designed for unshielded operation. His applications range from magnetocardiography and magnetomyography to magnetic-anomaly detection and space quantum technologies, emphasising sensors that are compact, manufacturable and field-deployable. His group combines device fabrication with real-world sensing demonstrations and is actively recruiting.

Holmes develops the magnetic-shielding, active field-nulling and sensor-calibration technology that allows subjects to move freely during OPM-MEG. He designs bi-planar and matrix coil systems that null the remnant field and its gradients in real time, keeping SERF sensors within their narrow operating range even as the head moves. He is Chief Scientist and a co-founder of Cerca Magnetics, the Nottingham spin-out that commercialises turnkey OPM-MEG systems.

Iivanainen develops OPM-MEG instrumentation and analysis, including sensor-array design, on-scalp spatial sampling and source-modelling methods, work he began at Aalto and continues at Sandia. His research quantifies how many sensors and what geometry are needed to capture the neuromagnetic field, and how to reconstruct sources from dense on-scalp data. He bridges hardware development and the signal-processing that extracts brain activity from it.
