I am an astronomer at the Australian National University. I do research on comets, quasars, high redshift galaxies, and novel interactive teaching techniques.

I grew up in London, studied in Cambridge and have worked with Steward Observatory in Tucson, Arizona, with the University of Melbourne, and have been based at the ANU since 1997.
