Research interests

My research is on novel optical components for controlling light. Currently, I work mostly on pixellated optical components that allow light rays to be refracted in novel ways that appear (but aren't actually) "forbidden" by wave optics, thus opening up new possibilities.

Specifically, I am developing spectacles designed to treat a range of eye conditions that affect a huge number of people worldwide, often with very severe consequences. The hope is that our work can help the people suffering from these conditions, and as the number of affected people is so huge my work has the potential to significantly improve many people's lives.

My novel optical components are also an opportunity to do "fun" things (well, fun for those who like this sort of thing) such as designing invisibility cloaks and optical wormholes using my novel optical components. This work is largely theoretical in nature.

Previously I have invented a device for sorting individual photons according to their orbital angular momentum; pioneered algorithms for shaping a light beam's 3D intensity distribution (which is relevant to a number of fields, for example optical trapping); and dabbled with optical resonators, most notably resonators with fractal eigenmodes (which are, sort of, analogous to video feedback; my mugshot shows a young me "doing" video feedback.)

Since 2017, I am a Fellow of the Optical Society (OSA) (now Optica).

In May 2012, I appeared as some form of expert on the BBC programme Coast (Series 7, Episode 1), trying to explain an atmospheric phenomenon called the "green flash".
