i am a cosmologist, a professor of physics at stanford university and the slac national accelerator laboratory, and the director of the kavli institute for particle astrophysics and cosmology.
my major research interests are focused on understanding the growth of structure in the universe, how structure formation drives galaxy formation, and how galaxies can be used to probe the the fundamental physics of the universe, including the nature of dark matter and dark energy. i use large computer simulations, physical and empirical models, and the deepest and largest galaxy surveys to determine how the universe formed and evolved. from 2014-2018 i was the co-spokesperson of the dark energy spectroscopic instrument (DESI), and am a founding member of the dark energy survey (DES) and the LSST dark energy science collaboration. i am the co-lead of SAGA (satellites around galactic analogs) survey, a study of the satellites of milky way analogs, and lead several large simulation programs including symphony and aemulus. |
