Overview
Background
Professor Tamara Davis is an astrophysicist who studies the elusive “dark energy” that’s accelerating the universe. She completed her PhD in 2004 at the University of New South Wales on theoretical cosmology and event horizons, then worked on supernova cosmology in two postdoctoral fellowships, the first at the Australian National University (collaborating with Lawrence Berkeley Laboratory) and the second at the University of Copenhagen. In 2008 she moved to Queensland and began mapping the galaxies in the Universe. She led the Dark Theme within the Australian Research Council Centre of Excellence for All-sky Astrophysics, and the Australian Dark Energy Survey - partnering with the international Dark Energy Survey. As of 2024 she is Deputy Director of the Australian Research Council Centre of Excellence for Gravitational Wave Discovery.
Her accolades include the Astronomical Society of Australia's Louise Webster Medal for early career research impact, the L'Oréal Women in Science Fellowship (Australia), the Australian Institute of Physics Women in Physics Lectureship, the Australian Academy of Science’s Nancy Millis Medal for outstanding female leadership in science, an Australian Research Council Laureate Fellowship, the Astronomical Society of Australia's Ellery Lectureship. She is a Fellow of the Australian Academy of Science (FAA) and a Member of the Order of Australia (AM).
