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.

Wasielewski's group uses ultrafast photoinduced electron transfer within covalently linked organic donor-acceptor molecules to generate pairs of entangled electron spins (spin-correlated radical ion pairs) that behave as optically-initialized, microwave-addressable molecular qubits. Building on this platform, the group demonstrated explicit quantum sensing of electric fields via molecular-recognition-induced changes in a spin-correlated radical pair, alongside DNA-hairpin-hosted spin-qubit pairs and chirality-induced spin selectivity effects -- extending photosynthetic radical-pair chemistry into a designed quantum-sensing and quantum-information platform.
