Research interests

My research lies at the interface between applied physics and advanced engineering, as recognised by my recent award of a five-year Royal Academy of Engineering Research Fellowship. My primary focus is the identification and exploitation of technologically useful point defects in diamond: this is driven through a mixture of electron paramagnetic resonance and coherent optical experiments, with an emphasis on the understanding and control of defects with the potential to act as spin-photon interfaces.

I am part of the Centre for Doctoral Training in Diamond Science and Technology - please see the DST website for a list of current PhD projects. I also work closely with my previous colleagues in the Networked Quantum Information Technologies (NQIT) quantum hub. As part of WP4: "Solid state node engineering", we are developing quantum computing nodes based on optical-cavity-enhanced colour centres in diamond.
