Welcome to the Brown University Observational Cosmology and Astrophysics group. Our research group is currently interested in both measuring the Universe at very large scales as well as in understanding exoplanets.  We specialize in developing new techniques to make these measurements. To carry out these projects we design and build ground-based, balloon-borne and space-based instruments and analyze the data from these experiments.
