About me

Me Center for Galaxy Evolution Fellow, University of California, Irvine

My research focuses on galaxy formation theory and its interface with cosmology. One of my primary interests is testing the standard ΛCDM model on galactic and sub-galactic scales, both with statistical samples of galaxies and halos, and in detail in the Milky Way. I use a combination of numerical simulations, analytic models, and observations in my work. See my publications for more of my interests.

While at the Max Planck Institute for Astrophysics, I led the Millennium-II Simulation project
(follow links for movies, images, scientific papers, and data access).
