Mark Halpern is a cosmologist whose experimental cosmology research focuses on measurements of the cosmic microwave background (CMB), the thermal radiation from the hot plasma that filled the universe for its first few hundred thousand years.
His research group at UBC is also involved in a number of efforts to understand the history of galaxy and star formation in the early universe through the properties and distribution of galaxies at light redshift.
Halpern’s group is also involved in efforts to build two new instruments to facilitate measurement of the universe at high redshift: the Balloon-borne Large Aperture Submillimeter Telescope (BLAST), an instrument designed to search for wavelengths emitted by distant galaxies but currently blocked by our atmosphere; and SCUBA2, a revolutionary camera being built for the James Clerk Maxwell Telescope.
