Barskiy develops zero- to ultralow-field NMR/MRI with parahydrogen (SABRE) hyperpolarization and spin chemistry, building magnet-free analytical platforms read out by OPM and diamond magnetometers. This vapour-phase approach reaches femto-to-picotesla sensitivities complementary to NV-center diamond ensemble quantum sensors (DEER, nano-NMR, T1 relaxometry) that operate near the pT/sqrt(Hz) regime.
