My work 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. I am currently working on something I call METATOYs, which stands for metamaterials for rays. These are structured surfaces that allow light rays to be refracted in ways arguably "forbidden" by wave optics.
