ARC Centre of Excellence for All Sky Astrophysics in 3 Dimensions (STEM Blitz February 2017)

Ryan-Weber leads the intergalactic medium research group at Swinburne. Her science focuses on detecting elements heavier than Helium in absorption at very high redshifts (12 billion years ago). To achieve this we use near-infrared spectroscopy towards high redshift quasars on the world's largest telescopes including Keck (Hawaii) and the VLT (Chile). She received her PhD from the University of Melbourne in 2004, spent 5 years at the University of Cambridge and commenced her position at Swinburne in 2009. Ryan-Weber is one of three Swinburne CIs for the CAASTRO-3D Centre of Excellence. Recorded on 10 February 2017.
