I do not currently have any faculty-funded PhD positions open. However, feel free to email me to discuss self-funded opportunities or alternative sources of funding. See here for any other current PhD opportunities in physics.

I am a theoretical and computational physicist in the areas of ultracold atoms and quantum optics. My research interests center on quantum fluids, in particular topological objects and phenomena in Bose-Einstein condensates, and the interaction of light and matter on atomic scales. Recent projects focus realisation of vortices in superfluids with internal polytope symmetries, together with experimental collaborators, a theoretical description of spin-Alice rings resulting from monopole with parallels in quantum-field theory, theoretical prediction of "superatom" behaviour in cooperative light scattering in atomic arrays, and a prediction that signatures of phonon dynamics in molecules in "noisy" environments could be detected in their photon response.

I completed my PhD at Lund University, Sweden. I subsequently held a Swedish Research Council postdoctoral stipend at University of Cambridge and there after a Leverhulme Early Career Fellowship and an EPSRC Postdoctoral Fellowship at the University of Southampton, before joining the University of East Anglia as a Research Fellow in 2016, becoming Lecturer in Physics in 2017. I was promoted to Associate Professor with effect from 2022.
