Matt Dobbs is an Associate Professor in the Department of Physics and associate member of the Department of Electrical and Computer Engineering at McGill University (Canada). He holds a Canada Research Chair and is a Senior Fellow in the Canadian Institute for Advanced Research Cosmology and Gravity program. Prof. Dobbs earned a Ph.D. (2002) in experimental Particle Physics from the University of Victoria (Canada), was awarded an Owen Chamberlain Fellowship at the Lawrence Berkeley Laboratory (USA) in 2002, and earned a Sloan Fellowship in 2009. In 2014 he was awarded the inaugural Dunlap Award for Innovation in Astronomical Research Tools and the Canadian Association of Physicists Herzberg Medal.


The aim of Prof. Dobbs' research is to improve our understanding of the fundamental constituents of the universe – including its origin, history, and fate – providing new insight into the early universe, where the laws of particle physics and cosmology intersect. His research group at McGill specializes in the design, construction, and operation of novel instrumentation and experiments to explore the early universe. Prof. Dobbs has journeyed to the ends of the earth to deploy his instruments in the best observing conditions, including the geographic South Pole and aboard stratospheric balloons.

  • The CMB polarization is one of the few tools we know of to probe physics at inflationary energy scales, where grand unified theories may manifest themselves. At McGill, we heavily involved with the South Pole Telescope polarimeter, the NASA balloon-borne experiment EBEX, and POLARBEAR. These experiments may unveil the signature of inflationary gravity waves using the CMB polarization.
  • Another fundamental unknown is the nature of Dark Energy, which presently accounts for about 70% of the energy density in the universe. I am involved with two experiments, APEX-SZ and the South Pole Telescope, which will use a subtle distortion of the CMB from Galaxy Clusters called the Sunyaev-Zel'dovich effect to measure the expansion history of the universe and gain new information about Dark Energy.
  • The Canadian Hydrogen Intensity Mapping Experiment (CHIME) is an exciting new project for mapping the 21cm signature from z=1-2.5.
