Background

My principal research interest is in the non-equilibrium dynamics of ultracold Bose gases. In particular I am interested in quantum vortex dynamics and quantum turbulence, non-equilibrium Bose-Einstein condensate dynamics and dynamical critical phenomena in the presence of finite temperatures and disorder, and bright solitary matter-waves and their application to interferometry. I am also interested in using ultracold-atom experiments as quantum simulators of physics in the early-universe. In addition to exploring fundamental theoretical questions in these areas, I have a strong interest in modelling current ultracold atom experiments, and working to propose new ones.


Areas of expertise: ultracold atomic physics; ultracold Bose gases; quantum vortex dynamics and turbulence, matter-wave solitons, matter-wave interferometry, quantum simulators.
