Research

Cosmology, large-scale structure of the Universe

Frieman's primary research is in cosmology, especially the formation of large-scale structure and the interplay between cosmology, particle physics, and astrophysics. Current research interests include the analysis of large-scale structure in galaxy surveys such as the Sloan Digital Sky Survey, the use of weak gravitational lensing observations to probe the distribution of mass on galaxy and cluster scales, searches for strongly lensed quasars to constrain halo dark matter profiles, and new probes of the dark energy. Frieman is a member of the Theoretical Astrophysics group at Fermilab, which has close connections with the cosmologists and theoretical astrophysicists at Chicago.
