Professor Tamara Davis is an astrophysicist who studies the elusive "dark energy" that's accelerating the universe. She's measured time-dilation in distant supernovae, helped make one of the largest maps of the distribution of galaxies in the universe, and is now measuring how supermassive black holes have grown over the last 12 billion years. She did her PhD at the University of New South Wales on theoretical cosmology and black holes, 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, before moving to Queensland to join the WiggleZ Dark Energy Survey team working on mapping the galaxies in the universe. She led the Dark Theme within the Australian Research Council Centre of Excellence for All-sky Astrophysics, is helping manage the OzDES survey - working with the international Dark Energy Survey, and is now working with the Dark Energy Spectroscopic Instrument project.

The Astronomical Society of Australia awarded her their Louise Webster Medal prize for the young researcher with the highest international impact in 2009, and she has since received the L'Oréal Women in Science Fellowship, the Australian Institute of Physics Women in Physics Lectureship, the Australian Academy of Science's Nancy Millis Medal for outstanding female leadership in science, and an Australian Research Council Laureate Fellowship.
