Professor Freese works on a wide range of topics in theoretical cosmology and astroparticle physics. She has been working to identify the dark matter and dark energy that permeate the Universe as well as to build a successful model for the early universe immediately after the Big Bang. She is author of a book, The Cosmic Cocktail: Three Parts Dark Matter, published in June 2014 by Princeton University Press.
Professor Freese has been awarded an Honorary Doctorate (honoris cause) from the University of Stockholm in September 2012. She is a Fellow of the American Physical Society. She was awarded a Simons Foundation Fellowship in Theoretical Physics in 2012.
