Prof. Hlozek studies a variety of problems in theoretical and observational cosmology through observations of the Cosmic Microwave Background, Type Ia supernovae and Baryon Acoustic Oscillations.
Using data from the Atacama Cosmology Telescope, her research focuses on constraining cosmological models, as well as determining the structure and amount of dark energy in the Universe.
She uses Baryon Acoustic Oscillations to constrain and test models of the Universe, and is interested in methods of extracting the signal from both spectroscopic and photometric galaxy surveys.
Hlozek also developed BEAMS, Bayesian Estimation Applied to Multiple Species, a statistical method for performing parameter estimation in the presence of contaminated cosmological data, which she applies to datasets such as the SDSS-II SN survey.
Hlozek studied at the University of Pretoria and the University of Cape Town. She received her DPhil from the University of Oxford in 2011, where she was a Rhodes Scholar. Before coming to the Dunlap, she was a Lyman Spitzer Jr. Postdoctoral Research Fellow in the Department of Astrophysics at Princeton University and the Spitzer-Cotsen Fellow in the Princeton Society of Fellows. She is also a Senior TED Fellow.
