Overview

Professor Bean's work centers on extracting information about cosmological theories using observations of the cosmic microwave background (CMB) and large scale structure (galaxies and clusters of galaxies), in particular working to understand the nature of dark energy, the properties of gravity on cosmic scales and the fundamental origins of primordial inflation.

She is involved in a number of astronomical experiments: the LSST Dark Energy Science Collaboration (and led the collaboration from 2015-17), the Dark Energy Spectroscopic Instrument (DESI) science team, the NASA Euclid science team and the NASA WFIRST High Latitude Survey Science Investigation Team. She is also involved in preparations for the Simons Observatory and a Cornell-led facility, CCAT-prime.
