Professor (Astrophysics), University of Southern Queensland

Jonti is an astronomer and astrobiologist based at the University of Southern Queensland, in Toowoomba, Queensland.

They first became interested in astronomy as a five-year-old, as a result of viewing an accidentally recorded episode of the Sky at Night.

Jonti has always been particularly interested in the Solar system, especially the small objects therein - the comets, asteroids and meteors.

In recent years, they've been expanding their research to include astrobiology and the search for, and study of, exoplanets.
