Andrew P Hearin, CASE Associate

Hearin is a member of the research staff in the Cosmological Physics and Advanced Computing group at Argonne. Hearin's research interests span a range of problems in cosmology and galaxy formation physics. He studies cosmological structure growth in the nonlinear regime using forward-modeling techniques and large-volume simulations. He is the lead developer of Halotools, an open-source python package for modeling the galaxy-halo connection. Hearin is an active member of numerous ongoing and near-future galaxy surveys such as the Dark Energy Science Collaboration in the Large Synoptic Survey Telescope (LSST-DESC), and the Dark Energy Spectroscopic Instrument (DESI). Much of Hearin’s research focuses on utilizing high-precision measurements from these surveys to understand the physics that shapes galaxy formation, and to uncover the physical nature of dark matter and dark energy.
