I am Professor of Theoretical Physics,  in the Theoretical Physics Group within the School of Physics and Astronomy at the University of Birmingham, UK, since February 2018.

Previously I was Professor of Theoretical Physics in the School of Physics, University of Bristol, UK.  While there I was Head of the Theory Group.  I still have research group in Bristol, involved in the research activities in Wave Geometry & Optical Field Theory and Knots in Physics & Applied Topology.  My research team, Scientific Properties of Complex Knots (part of a collaboration with colleagues in Durham University) has a Twitter feed, @SPOCKBristol.

My research interests are currently in singular optics and structured light (optical vortices, polarization singularities, optical angular momentum), and applied topology in physics (especially applications of knot theory in optics, quantum mechanics, and molecular biology).

In the last year, my teaching and administration responsibilities have included being Head of Theoretical Physics MSci, and Teaching and Learning Advisor for Physics,  teaching 4th yr (senior) Relativistic Field Theory, and 3rd yr (junior) Analytical Mechanics.
