Stalnaker runs an atomic-vapour magnetometry and direct frequency-comb spectroscopy lab and is a node of the GNOME network searching for exotic-field and dark-matter transients. 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.
