I\'m an astronomer and astrobiologist based at the University of Southern Queensland, in Toowoomba, Queensland. I first became interested in astronomy as a 5 year-old, as a result of viewing an accidentally recorded episode of the Sky at Night. I\'ve always been particularly interested in our own Solar system, especially the small objects therein - the comets, asteroids and meteors. In recent years, I\'ve been expanding my research to include astrobiology and the search for, and study of, exoplanets.
