Cullan Howlett

Cullan Howlett works in observational cosmology, using large galaxy surveys (such as DESI and SDSS) to study the large-scale structure of the universe, measure how fast the universe is expanding (the Hubble constant), and test how galaxies move and cluster over cosmic time. Much of the work involves statistical modelling of galaxy positions and velocities to constrain cosmological parameters, including cross-checks using gravitational-wave 'dark siren' events. Note that a few unrelated publications on cystic fibrosis appear in this record, likely due to author name overlap rather than this researcher's actual work.

Publication output has grown substantially over the last decade, rising sharply from single digits in the late 2010s to over 40-70 per year by 2024-2025, indicating an actively expanding research program.
