I’m interested in using stellar streams, dark matter substructure, and near-field cosmology to uncover the Milky Way’s assembly history. Below are the areas I’m currently working on.
I study the fossil record of the Milky Way: the stellar streams, disrupted globular clusters, and accreted dwarf galaxies that trace how our Galaxy came together. Using data from the DESI Milky Way Survey and galactic dynamics simulations, I look for tidal substructures in the halo and try to figure out where they came from.
