Current tension between local distance measurements of the Hubble constant, and those from the CMB, might point towards new physics beyond our current best cosmological models. Gravitationally lensed quasars offer an independent measure of the Hubble constant through time delay cosmography, however these systems are incredibly rare. My PhD focusses on developing techniques to identify lensed quasars in new imaging surveys, including the Dark Energy Survey, Pan-STARRS, and Gaia.
