... Research . ... I aim to understand the variety of processes that have driven galaxy formation and mass assembly across cosmological history via the resolved (star-by-star) study of nearby systems - in particular the Milky Way and Andromeda (especially their stellar halos and globular cluster populations), the Magellanic Clouds, and the myriad of smaller dwarfs that inhabit the "Local Group".б  . ... Globular clusters are fascinating objects in their own right. ...
