Research Description

Professor Vieira is an observational cosmologist who works across the electromagnetic spectrum. His scientific interests include: galaxy evolution and structure formation at high redshift; the star formation history of the Universe; the epoch of reionization; the cosmic microwave background. He builds experiments, conducts cosmological surveys, and performs followup observations of distant galaxies. He works with data from the South Pole Telescope, Herschel, Hubble, Spitzer, and ALMA. He is currently helping to build future mm and sub-millimeter facilities and pondering the cosmic evolution of dust and ionized carbon.
