Emma Veronica Ryan-Weber (born c. 1976) is an Australian astronomer, a professor in the Department of Physics and Astronomy at the Swinburne University of Technology in Melbourne, and director of the multi-institution Australian Research Council Centre of Excellence for All Sky Astrophysics in 3 Dimensions (ASTRO 3D).[1]
Research
Ryan-Weber's research concerns the composition of the intergalactic medium, determined by the absorption patterns of light from far-distant galaxies, and what the changes in this composition over time can tell us about how the universe has evolved.[2][3] For instance, her work on measuring the carbon in the early universe found less of it than expected, suggesting that some energy source other than carbon-rich massive stars was needed to reionize the hydrogen in the early universe, making it transparent.[4]
She obtained a five-year postdoctoral research position at the Institute of Astronomy, Cambridge,[2] from 2004 through 2008,[3] through which she gained access to several large optical telescopes. She returned to Australia to her present position at the Swinburne University of Technology,[2] initially as an Australian Research Council Queen Elizabeth II Fellow.[3]
At Swinburne, and as director of ASTRO 3D, Ryan-Weber has been a strong advocate for women in science, and over five years has brought the center up from having 30% women among its researchers to 50%.[2][6]
