McCamey is, for a candidate coming from NV ensemble sensing, the single most methodologically adjacent PI at UNSW. His laboratory does optically and electrically detected magnetic resonance on spins that are not defects in diamond: photogenerated spin-correlated radical pairs, triplet excitons in organic semiconductors, singlet-fission intermediates, and molecular spin systems. The instrumentation is the same toolkit — pulsed EPR, ODMR, dynamical decoupling, relaxometry — applied to systems where the spin is created by light and reports on chemistry. He directs the UNSW node of ARC Exciton Science. Positioned against the established body of NV-ensemble quantum sensing work — DEER, nanoscale NMR and T1 relaxometry protocols operating at pT/sqrt(Hz) field sensitivity — his group runs precisely those pulse sequences (Hahn echo, DEER, relaxometry) on a different spin species, and radical-pair spin chemistry is one of the few plausible mechanisms by which biology could be genuinely quantum — which makes this a strong landing spot for someone wanting to keep the NV skill set but change the physical system. Preferred attributes present: sensitivity-limited spin measurement, quantum-biology relevance.

Tesi leads an independent group at Stuttgart's Institute of Physical Chemistry working on optically addressable molecular spin systems -- the effort to reproduce the NV centre's defining trick (optical initialization and readout of a spin) in a designed molecule, where chemistry rather than crystal growth sets the properties. Work spans photogenerated spin-correlated radical pairs, ODMR on molecular chromophore-radical systems, spin-phonon coupling and coherence engineering, and embedding of molecular spins in films and matrices. Relative to the established NV-ensemble quantum-sensing playbook (DEER, nanoscale NMR, T1 relaxometry at pT/sqrt(Hz) ensemble sensitivity), this is arguably the most direct molecular analogue in the search: the target sensitivity and readout protocols are borrowed straight from NV ensembles, but the emitter is synthetic. Newer, smaller group; good fit for a postdoc who wants to own a direction rather than inherit one.
