Simon Murphy

Welcome! I am an astronomer in the School of Science at the University of New South Wales Canberra.

My research interests are focused on identifying and characterising some of the youngest stars in the Solar neighbourhood. These young, nearby star systems are ideal laboratories for understanding early stellar evolution and probing the diverse conditions under which stars and, importantly, planets form.

To accomplish this I use observations from a variety of telescopes and satellites, including the latest all-sky surveys here in Australia. I am also interested in the international Virtual Observatory effort, which is developing standards for the discovery, exchange and analysis of astronomical data by computers and astronomers alike.

From 2016 to 2020 I was a Vice Chancellor's Postdoctoral Fellow at UNSW Canberra, following a two year Gliese Fellowship at the University of Heidelberg, Germany. I completed my Ph.D. at the Australian National University's Mount Stromlo Observatory in 2012.
