Staff profile

I am originally from Hamilton, New Zealand. I initially studied Biology and Chemistry at the University of Waikato, before changing to Mathematics and Theoretical Physics,subsequently carrying out my doctoral studies in theoretical physics at the Leopold-Franzens University of Innsbruck, Austria. I then did postdoctoral work in Potsdam, Hannover, Oxford, and JILA (Colorado), before, in 2005, taking up a lectureship in the Durham University Department of Physics.

Research interests

Theoretical atomic physics, cold-atom physics, quantum nonlinear dynamics. At present, specifically, bright matter-wave solitons in attractively interacting Bose-Einstein condensates, and quantum resonance phenomena in periodically laser-pulsed clouds of cold atoms.
