Graeme Addison received his PhD in Astrophysics from the University of Oxford in 2012. He worked at the University of British Columbia as a CITA National Fellow until 2015 when he joined Johns Hopkins as a Research Assistant working with Charles Bennett.

Addison is a data-driven cosmologist whose main interests are the cosmic microwave background (CMB) and large-scale structure. As a graduate student he developed models for astrophysical signals that contribute to current high-resolution CMB experiments, in particular the cosmic infrared background and the thermal Sunyaev Zel’dovich effect. He has also spent time looking at the interpretation of baryon acoustic oscillation measurements in galaxy surveys. More generally he is interested in how we combine different cosmological data sets and assess their consistency as measurements become ever-more precise. Addison is a member of the Atacama Cosmology Telescope collaboration and has worked with data from a range of other telescopes including BLAST, Herschel, Spitzer, the South Pole Telescope, WMAP and Planck.
