I am a Professor of Theoretical Physics in the Theoretical Physics Group of the Physics Department, University of Bristol, UK. My research focuses primarily in geometric and topological aspects of wave physics, and more generally in the physics of optical and quantum mechanical waves.

I am particularly interested in:

· Singular and topological optics (the study of singular loci of scalar, vector, and tensor wave fields), including optical vortices, wave dislocations and polarization singularities.

· Statistical geometry and topology of random functions, and applications in quantum chaos, statistical optics, and cosmology.

· Geometry and topology of knots, links, braids and ribbons, especially those in spatially-extended fields.

· Mathematical methods for optical physics, including special functions, superoscillation & superresolution, quantum-classical correspondence, and ray-based asymptotics.

My main coworkers in Bristol Physics are James Ring and Sandy Taylor (PhD students), as well as Professors Michael Berry, John Hannay and John Nye. I also frequently work with Professor Miles Padgett and the Glasgow Optics Group.

In academic year 2013-14, I am lecturing 4th year Relativistic Field Theory, am teaching part of 3rd year Methods of Theoretical Physics, and am co-teaching the 4th year current topics strand Foundations of Modern Physics. I am also responsible, with Professor James Ladyman, for the Joint School of Physics and Philosophy.

I am currently Head of the Theoretical Physics Group in Bristol.

In academic year 2015-16, I am teaching

• 1st year Core Physics I: Mechanics & Matter (PHYS10006): Mechanics lectures

• 4th year Relativistic Field Theory (PHYSM3417)

• 4th year Foundations of Modern Physics (PHYSM0023)

• one lecture in 1st year Big Ideas in Science ("Symmetry" module CHEM10001)

Other teaching-related responsibilities:

• Teaching & Learning advisor for Physics;

• Head of Theoretical Physics Degree;

• Physics contact for Joint Mathematics-Physics Degree;

• Head of Theoretical Physics Group (including Group Project Officer)
