David received a PhD in physics (on diffraction theory) from Queensland University of Technology in 2003 (under principal adviser Dr Dmitri Gramotnev and associate advisor Prof. Gerard Milburn). He was then was a JSPS postdoctoral research fellow in the University of Tokushima under Prof. Masuo Fukui (discoverer of long-range plasmons in Prof. Stegeman's group). From 2006 David spent two years as associate researcher and plasmonics group leader in Prof Xiang Zhang’s group at UC Berkeley.

Research experience and interests includes theoretical analysis and experimental investigation of condensed matter physics, acoustic & optic wave propagation including plasmon-polaritons, slow and fast light, novel waveguides, and physics of periodic and layered media. Research highlights include: prediction and experimental confirmation of the plasmonic nanofocusing effect in tapered gap plasmon waveguides; discovery of channel-plasmons in sharp V-grooves (which have been identified by several groups as being the “ideal” nano-optical waveguide - see follow-up works of Prof. Bozhevolnyi); method for 100% transmission through sharp 90 degree bends in plasmon waveguides; prediction and experimental demonstration of two-dimensionally localised gap-plasmons; first nano-scale Fabry-Perot cavity; finite-difference methods for solution of electromagnetic problems and proposal of the compact 2D-FDTD approach; negative group velocity of plasmons (with Prof. Yongmin Liu, Northeastern); development of the low-loss nano-scale optical waveguide (subsequently used in the first plasmon nanolaser) and proper methods for assessing nano-scale waveguide mode confinement (with Prof. Rupert Oulton, Imperial); unidirectional nano-antennae and extreme control of electromagnetic radiation in complex media (with Dr Geoffroy Lerosey, CNRS).

Since November 2008, David has been an editor at Nature Photonics.
