Idit Zehavi is a professor in Physics and a member of the Center for Education and Research in Cosmology and Astrophysics at Case Western Reserve University. She received a PhD in Physics from the Hebrew University of Jerusalem and held research positions at Fermilab, University of Chicago and the University of Arizona, before coming to CWRU in 2006. She is also a visiting professor in the Physics Department at Durham University in the UK.

Zehavi is a cosmologist studying the large-scale structure of the universe and the galaxy-halo connection. She works at the interface of theory and observations, exploring the universe using both large surveys of galaxies and state-of-the-art numerical simulations of structure and galaxy formation. She is focused on studying the clustering properties of galaxies and the complex relation between galaxies and dark matter halos.
