My research is mostly theoretical and related to controlling light beams. I have, for example, pioneered an algorithm for shaping a light beam's 3D intensity distribution. This sort of work is relevant to a number of fields, for example optical trapping, which other people in the group do in the lab. Currently, I working on something I call METATOYs, which stands for metamaterials for rays. These are structured surfaces that allow light rays to be refracted in novel ways that appear (but aren't actually) "forbidden" by wave optics.

I spend a fair bit of time being the Green Champion for the College of Science & Engineering. As part of this role, I sit on the University's Carbon Management Committee.

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".
