Lotz received her PhD in astrophysics from Johns Hopkins University in 2003 and specializes in galaxy evolution and morphology, the high-redshift Universe and gravitational lensing. She most recently held a tenured associate astronomer position at STScI and a joint appointment as a research scientist at Johns Hopkins University. She is a leading expert in the field of galaxy mergers, and makes use of both ground-based and space telescopes to track the growth of galaxies over cosmic time. She led the Hubble Frontier Fields program, one of the largest programs undertaken with Hubble to detect the faintest distant galaxies yet seen.
