About

Dr. Sarah Pearson is an Assistant Professor at the University of Copenhagen, Denmark. Her research primarily focuses on the study of stellar streams and the dynamics of galaxy halos, with recent publications investigating globular clusters and dwarf galaxies. She employs observational data from facilities such as APOGEE, Gaia, and MUSE to explore the formation and evolution of galactic structures.
