Wendy Freedman
Wendy Freedman is the John and Marion Sullivan University Professor in Astronomy and Astrophysics at the University of Chicago. Her research is in observational cosmology (measures of the expansion rate of the universe using JWST, the Hubble Space Telescope, Spitzer Space Telescope and the ground-based Magellan telescope) and her current projects involve measurements of the Hubble constant — the current expansion rate, as well as the past expansion rate, providing constraints on the acceleration of the universe and dark energy. Her other field of interest is the stellar populations of galaxies, the evolution of galaxies, and the initial mass function. In 2023 she was elected as a Fellow of the Royal Society.
