How did the Universe form and evolve and what is it made of? Our group works on a range of topics in cosmology and astrophysics, with a focus on the formation of cosmological structure in the Universe, its impact on galaxy formation, and its use in determining the nature of dark matter and dark energy. We build and analyze numerical simulations and develop models of large scale structure and galaxy formation for comparison with large observational datasets, and develop new techniques to learn about the dark side of the Universe from these data. We are actively involved in the ongoing Dark Energy Survey (DES), the Dark Energy Spectroscopic Instrument (DESI) and the Large Synoptic Survey Telescope (LSST), and also work on finding, measuring, and modeling dwarf galaxies with the SAGA survey.
