I was co-Investigator on a number of HST proposals to observe strong gravitational lenses detected in SDSS-III (SLACS) and SDSS-IV (BELLS), which led to a number of publications. There are significant challenges remaining in the data analysis in order to dissect these galaxies in luminous and dark components, and there are new candidates from SDSS-IV (SILO) that are ideal for followup HST imaging.
