Biography

Originally from Ceredigion in West Wales, I moved to Durham in 2008 where I studied for a four year integrated masters in theoretical physics, followed by a PhD in the Atomic and Molecular group here. Having finished my PhD in May 2016, I am now doing a postdoc with Professors Simon Gardiner, Charles Adams and Ifan Hughes.

Research interests

I am interested in the interaction of light with dense atomic ensembles. In particular, my work has focussed on the modification of this atom-light interaction due to strong dipole-dipole interactions between the atoms. This cooperative behaviour can, for example, manifest as a modified decay rate (superradiance and subradiance), shifted energy levels, Fano resonances, and modified scattering properties. I have been particularly interested in the cooperative behaviour of periodic atomic arrays.
