Katie Mack is currently a Discovery Early Career Researcher Award (DECRA) from the Australian Research Council on the topic: "Dark matter particle physics and the first sources of light in the universe." She is based at the University of Melbourne in the Astrophysics Group, part of the School of Physics.
Previously, she held a Postdoctoral Fellowship from the STFC at the University of Cambridge in the Kavli Institute for Cosmology / Institute of Astronomy. She received her Ph.D. in astrophysics at Princeton University and her undergraduate degree in physics at Caltech.
Her research has mainly been in particle physics, cosmology and theoretical astrophysics. Her Ph.D. thesis was on connections between early universe theory and astronomical observation with Professor Paul Steinhardt.
Her current interests include early universe physics, dark matter, the epoch of reionization, big bang relics, compact objects, and supermassive black holes. The unifying goal in all her work is to find ways to use observational cosmology to better understand the fundamental physical nature of the components and evolution of the universe.
