Sidney is a postdoctoral associate working with the Dark Energy Survey (DES) collaboration, the Rubin Observatory Legacy Survey of Space and Time Dark Energy Science Collaboration (LSST DESC), and the Roman Cosmology with High Latitude Imaging Survey Project Infrastructure Team (Roman HLIS PIT) for the Nancy Grace Roman Space Telescope. Sidney uses image simulations to help these experiments achieve the systematic precision necessary to measure weak lensing cosmic shear for cosmology.
