Summary:

Duellmann heads nuclear chemistry at JGU (TRIGA reactor site) with joint appointments at GSI and the Helmholtz Institute Mainz, working on the production, chemical separation and characterization of the heaviest elements. For this search the relevant thread is 229Th: his group supplies and prepares the isomeric thorium samples and molecular thorium ions that Wendt's laser spectroscopy and Schmidt-Kaler's ion traps interrogate en route to a nuclear clock, and he is part of the broader radioactive-molecule programme aimed at symmetry-violation searches. Relative to the established NV-ensemble quantum-sensing playbook (DEER, nanoscale NMR, T1 relaxometry at pT/sqrt(Hz) ensemble sensitivity), the pivot is toward the next frontier of frequency metrology, where the 'sensor' is a nucleus rather than an electron shell -- an unusually good chemistry/physics interface for a postdoc.

Summary:

NON-PREFERRED (borderline precision-measurement pivot, kept for review). Garcia Ruiz develops precision laser spectroscopy of atoms and molecules built from short-lived radioactive nuclei (at CERN-ISOLDE and the new FRIB facility) to measure nuclear charge radii, moments, and to search for symmetry-violating effects (parity/time-reversal violation) analogous to eEDM searches; it is fundamental precision measurement rather than a deployable quantum sensor, but shares techniques and motivation with the eEDM/precision-AMO quantum-sensing cluster.
