Phase structure of a chaotic 2+1-dimensional Bose-Einstein condensate, showing presence of multiple topological defects. The spatial and temporal evolution of this wavefunction is governed by a non-linear generalisation of the Schrodinger equation, known as the Gross-Pitaevskii equation. Source: Y.-R.Tan, D.M.

David is a theoretical physicist who enjoys working in a variety of research areas, from classical and quantum optics through to wavepacket dynamics and superconductivity.

Current research interests include:

• Phase retrieval and aberration balancing in imperfect coherent imaging systems
• Topological defects in radiation and matter wave-fields
• Non-integral Maslov indices and their application to wavepacket evolution
• Foundations of coherence theory of stochastic fields
• Phase retrieval in dissipative non-linear quantum systems
• Phase-contrast tomography
• X-ray lithography
• Holographic microscopy
• Hybrid hardware-software optical imaging systems (“omni optics”)
• Convergent-beam X-ray diffraction

David also enjoys teaching, and will be taking the following subjects in 2007:

• Quantum mechanics (third year and fourth year)
• Advanced quantum mechanics (fourth year)
• Relativistic particles and fields (third year)
• Particle physics (third year)
• Classical wave optics (third year)

He recently published a book, details of which can be found here.
