My research interests are in stars, planets, habitability and the emergence of life. I’m interested in characterising the uniqueness of the Solar System, specifically how its chemistry and architecture compare to the broad demographics of star-planet systems found throughout the Milky Way. I’m currently part of the Galactic Archaeology, Stars, and Planets (GASP) group at the Research School of Astronomy and Astrophysics (RSAA). My work focuses on how we can best identify, model, and determine the properties of binary star systems.

 I have previously worked to determine if the chemical compositions of stars can be used as a method to infer the past formation of terrestrial exoplanets using data from HARPS. The broad goals of my current research are focused on examining the origins and distribution of over 30 elements in the Milky Way using the spectra of millions of stars observed by the GALAH survey. I am particularly focused on developing methods to determine the abundances of elements in binary systems.
