Research interests

In addition to doing research, I have an interest in promoting research to a wide audience through...

  • ...interactive web pages: I have written the Java applets on the group's web pages;
  • ...films: I have introduced into the Glasgow curriculum a film project in which undergraduate students produce a short film, aimed at students entering University, that explains an aspect of the department's research;
  • ...computer visualization: surely, the core of optics is about visual things, and photorealistic ray-tracing simulations form an integral part of my work on METATOYs.
