Summary:

Ardavan leads the Quantum Spin Dynamics group, studying quantum coherent phenomena in condensed matter. Central to the lab's quantum sensing relevance: (1) molecular spin qubits — using pulsed EPR/DEER to characterise and control multi-spin registers ({Cr7Ni} molecular rings, nitroxide radical chains) assembled into qubit networks, measuring coherence times, inter-qubit couplings, and demonstrating spin-electric coupling in molecular magnets; (2) DNA-assembled molecular quantum devices — using DNA nanostructures to precisely position molecular spin qubits for multi-qubit sensing and quantum information applications; (3) surface atom spin resonance — STM-based coherent spin control of individual atoms on surfaces at nanosecond timescales. Uses X-band through W-band pulsed EPR at Centre for Advanced Electron Spin Resonance (CAESR), Oxford.

Summary:

PREFERRED. Bathe's lab programs DNA and RNA into custom 2D/3D nanoscale materials (DNA origami via the DAEDALUS algorithm) for applications spanning vaccines/therapeutics, massive molecular data storage, and — most relevant here — using DNA as a programmable scaffold to organize photonic and quantum-optical elements (mimicking quantum coherence effects seen in photosynthetic light-harvesting) and single-molecule optical biosensing.
