She received a Ph.D. in Physics from the Hebrew University of Jerusalem, Israel. She held research positions at Fermi National Accelerator Laboratory, the University of Chicago and the University of Arizona, before joining CWRU in 2006. Her research interests include cosmology and the large-scale structure of the universe, galaxy formation and evolution, and cosmic flows. She is an astrophysicist working at the interface of theory and observations, performing studies using large surveys of galaxies as well as numerical simulations. In particular, she has been focused on measuring and interpreting galaxy clustering in the Sloan Digital Sky Survey, an ambitious survey mapping a quarter of the sky.
