Tobias Marriage explores the character and evolution of the universe through measurements of the cosmic microwave background (CMB), the remnant light from the big bang. Tobias co-leads of the Cosmology Large Angular Scale Surveyor (CLASS) project. He also helped build the first receiver and analysis pipeline for the Atacama Cosmology Telescope (ACT).
