Garreth joined Steward Observatory in the fall of 2019. His research lies at the interface between observational and theoretical astronomy, combining state-of-the-art hydrodynamical simulations, survey data and machine-learning techniques. He is interested in how the diversity of present-day galaxy populations arises during their assembly and how underlying processes like mergers, feedback and environmental processes drive these changes. His current work focusses on the formation mechanisms, evolution and morphology of low-surface-brightness galaxy populations that have gone almost unnoticed in previous wide-area surveys and represent an important additional axis for constraining our understanding of galaxy evolution.
